Wikibooks (previously called Wikimedia Free Textbook Project and Wikimedia-Textbooks ) is a wiki -based Wikimedia project hosted by the Wikimedia Foundation for the creation of free content digital textbooks and annotated texts that anyone can edit.
135-574: Initially, the project was created solely in English in July 2003; a later expansion to include additional languages was started in July 2004. As of November 2024, there are Wikibooks sites active for 77 languages comprising a total of 383,831 articles and 1,752 recently active editors. The wikibooks.org domain was registered on July 19, 2003. It was launched to host and build free textbooks on subjects such as organic chemistry and physics , in response to
270-421: A bonobo named Kanzi learned to express itself using a set of symbolic lexigrams . Similarly, many species of birds and whales learn their songs by imitating other members of their species. However, while some animals may acquire large numbers of words and symbols, none have been able to learn as many different signs as are generally known by an average 4 year old human, nor have any acquired anything resembling
405-418: A semantic fact (i.e., the proposition that is represented by "The horse is red"). In other words, a propositional function is like an algorithm. The meaning of "red" in this case is whatever takes the entity "the horse" and turns it into the statement, "The horse is red." Linguists have developed at least two general methods of understanding the relationship between the parts of a linguistic string and how it
540-504: A 2017 study on Ardipithecus ramidus challenges this belief. Scholarly opinions vary as to the developments since the appearance of the genus Homo some 2.5 million years ago. Some scholars assume the development of primitive language-like systems (proto-language) as early as Homo habilis (2.3 million years ago) while others place the development of primitive symbolic communication only with Homo erectus (1.8 million years ago) or Homo heidelbergensis (0.6 million years ago), and
675-411: A clause can contain another clause (as in "[I see [the dog is running]]"). Human language is the only known natural communication system whose adaptability may be referred to as modality independent . This means that it can be used not only for communication through one channel or medium, but through several. For example, spoken language uses the auditive modality, whereas sign languages and writing use
810-493: A combination of segmental and suprasegmental elements. The segmental elements are those that follow each other in sequences, which are usually represented by distinct letters in alphabetic scripts, such as the Roman script. In free flowing speech, there are no clear boundaries between one segment and the next, nor usually are there any audible pauses between them. Segments therefore are distinguished by their distinct sounds which are
945-502: A complete list with totals, see Wikimedia Statistics. Meng-Fen et al suggested that while there isn't much social connection between contributors of wikibooks, the contributors had no major issues coordinating to write books. Language Language is a structured system of communication that consists of grammar and vocabulary . It is the primary means by which humans convey meaning, both in spoken and signed forms, and may also be conveyed through writing . Human language
1080-597: A convention exactly is, and how it is studied, and second regards the extent that conventions even matter in the study of language. David Kellogg Lewis proposed a worthy reply to the first question by expounding the view that a convention is a "rationally self-perpetuating regularity in behavior". However, this view seems to compete to some extent with the Gricean view of speaker's meaning, requiring either one (or both) to be weakened if both are to be taken as true. Some have questioned whether or not conventions are relevant to
1215-421: A different medium, include writing (including braille ), sign (in manually coded language ), whistling and drumming . Tertiary modes – such as semaphore , Morse code and spelling alphabets – convey the secondary mode of writing in a different medium. For some extinct languages that are maintained for ritual or liturgical purposes, writing may be the primary mode, with speech secondary. When described as
1350-606: A finite, usually very limited, number of possible ideas that can be expressed. In contrast, human language is open-ended and productive , meaning that it allows humans to produce a vast range of utterances from a finite set of elements, and to create new words and sentences. This is possible because human language is based on a dual code, in which a finite number of elements which are meaningless in themselves (e.g. sounds, letters or gestures) can be combined to form an infinite number of larger units of meaning (words and sentences). However, one study has demonstrated that an Australian bird,
1485-685: A natural-sounding rhythm and a relatively normal sentence structure . The second area is Broca's area , in the posterior inferior frontal gyrus of the dominant hemisphere. People with a lesion to this area develop expressive aphasia , meaning that they know what they want to say, they just cannot get it out. They are typically able to understand what is being said to them, but unable to speak fluently. Other symptoms that may be present in expressive aphasia include problems with word repetition . The condition affects both spoken and written language. Those with this aphasia also exhibit ungrammatical speech and show inability to use syntactic information to determine

#17327759569421620-419: A range of correctness. He also argued that primitive names had a natural correctness, because each phoneme represented basic ideas or sentiments. For example, for Plato the letter l and its sound represented the idea of softness. However, by the end of Cratylus , he had admitted that some social conventions were also involved, and that there were faults in the idea that phonemes had individual meanings. Plato
1755-407: A real commonality of form, he is more often considered a proponent of moderate realism . The Stoics made important contributions to the analysis of grammar, distinguishing five parts of speech: nouns, verbs, appellatives (names or epithets ), conjunctions and articles . They also developed a sophisticated doctrine of the lektón associated with each sign of a language, but distinct from both
1890-522: A referent. Such a "mediated reference" view has certain theoretical advantages over Mill's view. For example, co-referential names, such as Samuel Clemens and Mark Twain , cause problems for a directly referential view because it is possible for someone to hear "Mark Twain is Samuel Clemens" and be surprised – thus, their cognitive content seems different. Despite the differences between the views of Frege and Russell, they are generally lumped together as descriptivists about proper names. Such descriptivism
2025-698: A request by Misplaced Pages contributor Karl Wick. Two major sub-projects, Wikijunior and Wikiversity , were created within Wikibooks before its official policy was later changed so that future incubator-type projects are started according to the Wikimedia Foundation's new project policy. In August 2006, Wikiversity became an independent Wikimedia Foundation project. Since 2008, Wikibooks has been included in BASE . In June 2016, Compete.com estimated that Wikibooks had 1,478,812 unique visitors. Wikijunior
2160-416: A result of their different articulations, and can be either vowels or consonants. Suprasegmental phenomena encompass such elements as stress , phonation type, voice timbre , and prosody or intonation , all of which may have effects across multiple segments. Consonants and vowel segments combine to form syllables , which in turn combine to form utterances; these can be distinguished phonetically as
2295-411: A rich set of case suffixes that provide details about the instrument used to perform an action. Others lack such grammatical precision in the oral mode, but supplement it with gesture to convey that information in the sign mode. In Iwaidja , for example, 'he went out for fish using a torch' is spoken as simply "he-hunted fish torch", but the word for 'torch' is accompanied by a gesture indicating that it
2430-641: A science since the first grammatical descriptions of particular languages in India more than 2000 years ago, after the development of the Brahmi script . Modern linguistics is a science that concerns itself with all aspects of language, examining it from all of the theoretical viewpoints described above. The academic study of language is conducted within many different disciplinary areas and from different theoretical angles, all of which inform modern approaches to linguistics. For example, descriptive linguistics examines
2565-430: A series of images of imaginary aliens. Whether each alien was friendly or hostile was determined by certain subtle features but participants were not told what these were. They had to guess whether each alien was friendly or hostile, and after each response they were told if they were correct or not, helping them learn the subtle cues that distinguished friend from foe. A quarter of the participants were told in advance that
2700-536: A sign is encoded and transmitted by a sender through a channel to a receiver who decodes it. Some of the properties that define human language as opposed to other communication systems are: the arbitrariness of the linguistic sign, meaning that there is no predictable connection between a linguistic sign and its meaning; the duality of the linguistic system, meaning that linguistic structures are built by combining elements into larger structures that can be seen as layered, e.g. how sounds build words and words build phrases;
2835-426: A specific instance of a language system, and parole for the concrete use of speech in a particular language. When speaking of language as a general concept, definitions can be used which stress different aspects of the phenomenon. These definitions also entail different approaches and understandings of language, and they also inform different and often incompatible schools of linguistic theory . Debates about
SECTION 20
#17327759569422970-521: A system of symbolic communication , language is traditionally seen as consisting of three parts: signs , meanings , and a code connecting signs with their meanings. The study of the process of semiosis , how signs and meanings are combined, used, and interpreted is called semiotics . Signs can be composed of sounds, gestures, letters, or symbols, depending on whether the language is spoken, signed, or written, and they can be combined into complex signs, such as words and phrases. When used in communication,
3105-650: A system that is largely cultural, learned through social interaction. Continuity-based theories are held by a majority of scholars, but they vary in how they envision this development. Those who see language as being mostly innate, such as psychologist Steven Pinker , hold the precedents to be animal cognition , whereas those who see language as a socially learned tool of communication, such as psychologist Michael Tomasello , see it as having developed from animal communication in primates: either gestural or vocal communication to assist in cooperation. Other continuity-based models see language as having developed from music ,
3240-488: A theory is Noam Chomsky , the originator of the generative theory of grammar , who has defined language as the construction of sentences that can be generated using transformational grammars. Chomsky considers these rules to be an innate feature of the human mind and to constitute the rudiments of what language is. By way of contrast, such transformational grammars are also commonly used in formal logic , in formal linguistics , and in applied computational linguistics . In
3375-543: A view already espoused by Rousseau , Herder , Humboldt , and Charles Darwin . A prominent proponent of this view is archaeologist Steven Mithen . Stephen Anderson states that the age of spoken languages is estimated at 60,000 to 100,000 years and that: Researchers on the evolutionary origin of language generally find it plausible to suggest that language was invented only once, and that all modern spoken languages are thus in some way related, even if that relation can no longer be recovered ... because of limitations on
3510-516: A way predicted by grammatical gender . For example, when asked to describe a "key"—a word that is masculine in German and feminine in Spanish—the German speakers were more likely to use words like "hard", "heavy", "jagged", "metal", "serrated" and "useful" whereas Spanish speakers were more likely to say "golden", "intricate", "little", "lovely", "shiny" and "tiny". To describe a "bridge", which
3645-451: A whole was understood to be a matter of philosophy of language. In continental philosophy , the foundational work in the field was Ferdinand de Saussure 's Cours de linguistique générale , published posthumously in 1916. The topic that has received the most attention in the philosophy of language has been the nature of meaning, to explain what "meaning" is, and what we mean when we talk about meaning. Within this area, issues include:
3780-415: Is modality -independent, but written or signed language is the way to inscribe or encode the natural human speech or gestures. Depending on philosophical perspectives regarding the definition of language and meaning, when used as a general concept, "language" may refer to the cognitive ability to learn and use systems of complex communication, or to describe the set of rules that makes up these systems, or
3915-472: Is a longitudinal wave propagated through the air at a frequency capable of vibrating the ear drum . This ability depends on the physiology of the human speech organs. These organs consist of the lungs, the voice box ( larynx ), and the upper vocal tract – the throat, the mouth, and the nose. By controlling the different parts of the speech apparatus, the airstream can be manipulated to produce different speech sounds. The sound of speech can be analyzed into
4050-483: Is a subproject of Wikibooks that specializes in books for children. The project consists of both a magazine and a website, and is currently being developed in English, Danish, Finnish, French, German, Italian, Japanese, Spanish, Arabic and Bangla. It is funded by a grant from the Beck Foundation. While some books are original, others began as text copied over from other sources of free content textbooks found on
4185-480: Is a tradition called speculative grammar which existed from the 11th to the 13th century. Leading scholars included Martin of Dacia and Thomas of Erfurt (see Modistae ). Linguists of the Renaissance and Baroque periods such as Johannes Goropius Becanus , Athanasius Kircher and John Wilkins were infatuated with the idea of a philosophical language reversing the confusion of tongues , influenced by

4320-479: Is acquired through learning. Estimates of the number of human languages in the world vary between 5,000 and 7,000. Precise estimates depend on an arbitrary distinction (dichotomy) established between languages and dialects . Natural languages are spoken , signed, or both; however, any language can be encoded into secondary media using auditory, visual, or tactile stimuli – for example, writing, whistling, signing, or braille . In other words, human language
4455-588: Is called linguistics . Critical examinations of languages, such as philosophy of language, the relationships between language and thought , how words represent experience, etc., have been debated at least since Gorgias and Plato in ancient Greek civilization . Thinkers such as Jean-Jacques Rousseau (1712–1778) have argued that language originated from emotions, while others like Immanuel Kant (1724–1804) have argued that languages originated from rational and logical thought. Twentieth century philosophers such as Ludwig Wittgenstein (1889–1951) argued that philosophy
4590-563: Is called a language isolate . There are also many unclassified languages whose relationships have not been established, and spurious languages may have not existed at all. Academic consensus holds that between 50% and 90% of languages spoken at the beginning of the 21st century will probably have become extinct by the year 2100. The English word language derives ultimately from Proto-Indo-European * dn̥ǵʰwéh₂s "tongue, speech, language" through Latin lingua , "language; tongue", and Old French language . The word
4725-435: Is characterized by its cultural and historical diversity, with significant variations observed between cultures and across time. Human languages possess the properties of productivity and displacement , which enable the creation of an infinite number of sentences, and the ability to refer to objects, events, and ideas that are not immediately present in the discourse. The use of human language relies on social convention and
4860-534: Is common for oral language to be accompanied by gesture, and for sign language to be accompanied by mouthing . In addition, some language communities use both modes to convey lexical or grammatical meaning, each mode complementing the other. Such bimodal use of language is especially common in genres such as story-telling (with Plains Indian Sign Language and Australian Aboriginal sign languages used alongside oral language, for example), but also occurs in mundane conversation. For instance, many Australian languages have
4995-546: Is deeply counterintuitive. Hence, names are rigid designators , according to Kripke. That is, they refer to the same individual in every possible world in which that individual exists. In the same work, Kripke articulated several other arguments against " Frege–Russell " descriptivism (see also Kripke's causal theory of reference ). The whole philosophical enterprise of studying reference has been critiqued by linguist Noam Chomsky in various works. It has long been known that there are different parts of speech . One part of
5130-606: Is different from them, and perceptibles are apprehended each by the one kind of organ, speech by another. Hence, since the objects of sight cannot be presented to any other organ but sight, and the different sense-organs cannot give their information to one another, similarly speech cannot give any information about perceptibles. Therefore, if anything exists and is comprehended, it is incommunicable. There are studies that prove that languages shape how people understand causality. Some of them were performed by Lera Boroditsky . For example, English speakers tend to say things like "John broke
5265-474: Is feminine in German and masculine in Spanish, the German speakers said "beautiful", "elegant", "fragile", "peaceful", "pretty" and "slender", and the Spanish speakers said "big", "dangerous", "long", "strong", "sturdy" and "towering". This was the case even though all testing was done in English, a language without grammatical gender. In a series of studies conducted by Gary Lupyan, people were asked to look at
5400-534: Is not necessarily true that if Aristotle existed then Aristotle was any one, or all, of these descriptions. Aristotle may well have existed without doing any single one of the things for which he is known to posterity. He may have existed and not have become known to posterity at all or he may have died in infancy. Suppose that Aristotle is associated by Mary with the description "the last great philosopher of antiquity" and (the actual) Aristotle died in infancy. Then Mary's description would seem to refer to Plato. But this
5535-503: Is obstructed, commonly at the lips, teeth, alveolar ridge , palate , velum , uvula , or glottis . Each place of articulation produces a different set of consonant sounds, which are further distinguished by manner of articulation , or the kind of friction, whether full closure, in which case the consonant is called occlusive or stop , or different degrees of aperture creating fricatives and approximants . Consonants can also be either voiced or unvoiced , depending on whether

5670-477: Is often considered a proponent of extreme realism . Aristotle interested himself with issues of logic , categories, and the creation of meaning. He separated all things into categories of species and genus . He thought that the meaning of a predicate was established through an abstraction of the similarities between various individual things. This theory later came to be called nominalism . However, since Aristotle took these similarities to be constituted by
5805-478: Is partly something originally given, partly that which develops freely. And just as the individual can never reach the point at which he becomes absolutely independent ... so too with language. The phrase " linguistic turn " was used to describe the noteworthy emphasis that contemporary philosophers put upon language. Language began to play a central role in Western philosophy in the early 20th century. One of
5940-401: Is possible to use the concept of functions to describe more than just how lexical meanings work: they can also be used to describe the meaning of a sentence. In the sentence "The horse is red", "the horse" can be considered to be the product of a propositional function . A propositional function is an operation of language that takes an entity (in this case, the horse) as an input and outputs
6075-476: Is put together: syntactic and semantic trees. Syntactic trees draw upon the words of a sentence with the grammar of the sentence in mind; semantic trees focus upon the role of the meaning of the words and how those meanings combine to provide insight onto the genesis of semantic facts. Some of the major issues at the intersection of philosophy of language and philosophy of mind are also dealt with in modern psycholinguistics . Some important questions regard
6210-407: Is quite limited, though it has advanced considerably with the use of modern imaging techniques. The discipline of linguistics dedicated to studying the neurological aspects of language is called neurolinguistics . Early work in neurolinguistics involved the study of language in people with brain lesions, to see how lesions in specific areas affect language and speech. In this way, neuroscientists in
6345-454: Is really the study of language itself. Major figures in contemporary linguistics of these times include Ferdinand de Saussure and Noam Chomsky . Language is thought to have gradually diverged from earlier primate communication systems when early hominins acquired the ability to form a theory of mind and shared intentionality . This development is sometimes thought to have coincided with an increase in brain volume, and many linguists see
6480-415: Is sometimes used to refer to codes , ciphers , and other kinds of artificially constructed communication systems such as formally defined computer languages used for computer programming . Unlike conventional human languages, a formal language in this sense is a system of signs for encoding and decoding information . This article specifically concerns the properties of natural human language as it
6615-435: Is specific to the ability to use language, not to the physiology used for speech production. With technological advances in the late 20th century, neurolinguists have also incorporated non-invasive techniques such as functional magnetic resonance imaging (fMRI) and electrophysiology to study language processing in individuals without impairments. Spoken language relies on human physical ability to produce sound , which
6750-465: Is studied in the discipline of linguistics . As an object of linguistic study, "language" has two primary meanings: an abstract concept, and a specific linguistic system, e.g. " French ". The Swiss linguist Ferdinand de Saussure , who defined the modern discipline of linguistics, first explicitly formulated the distinction using the French word langage for language as a concept, langue as
6885-437: Is supported by the fact that all cognitively normal children raised in an environment where language is accessible will acquire language without formal instruction. Languages may even develop spontaneously in environments where people live or grow up together without a common language; for example, creole languages and spontaneously developed sign languages such as Nicaraguan Sign Language . This view, which can be traced back to

#17327759569427020-469: Is that language is such a unique human trait that it cannot be compared to anything found among non-humans and that it must therefore have appeared suddenly in the transition from pre-hominids to early man. These theories can be defined as discontinuity-based. Similarly, theories based on the generative view of language pioneered by Noam Chomsky see language mostly as an innate faculty that is largely genetically encoded, whereas functionalist theories see it as
7155-404: Is the default modality for language in all cultures. The production of spoken language depends on sophisticated capacities for controlling the lips, tongue and other components of the vocal apparatus, the ability to acoustically decode speech sounds, and the neurological apparatus required for acquiring and producing language. The study of the genetic bases for human language is at an early stage:
7290-497: Is to what extent language influences thought and vice versa. There have been a number of different perspectives on this issue, each offering a number of insights and suggestions. Linguists Sapir and Whorf suggested that language limited the extent to which members of a "linguistic community" can think about certain subjects (a hypothesis paralleled in George Orwell 's novel Nineteen Eighty-Four ). In other words, language
7425-439: Is used in metaphor , metonyms and other figures of speech). A proper suppositio , in turn, can be either formal or material accordingly when it refers to its usual non-linguistic referent (as in "Charles is a man"), or to itself as a linguistic entity (as in " Charles has seven letters"). Such a classification scheme is the precursor of modern distinctions between use and mention , and between language and metalanguage. There
7560-458: Is used socially. Specific interests include the topics of language learning , language creation, and speech acts . Secondly, the question of how language relates to the minds of both the speaker and the interpreter is investigated. Of specific interest is the grounds for successful translation of words and concepts into their equivalents in another language. An important problem which touches both philosophy of language and philosophy of mind
7695-488: The Enlightenment and its debates about human origins, it became fashionable to speculate about the origin of language. Thinkers such as Rousseau and Johann Gottfried Herder argued that language had originated in the instinctive expression of emotions, and that it was originally closer to music and poetry than to the logical expression of rational thought. Rationalist philosophers such as Kant and René Descartes held
7830-709: The Vienna Circle , logical positivists , and Willard Van Orman Quine . In the West, inquiry into language stretches back to the 5th century BC with Socrates , Plato , Aristotle , and the Stoics . Linguistic speculation predated systematic descriptions of grammar which emerged c. the 5th century BC in India and c. the 3rd century BC in Greece. In the dialogue Cratylus , Plato considered

Additionally, pied babblers have demonstrated the ability to generate two functionally distinct vocalisations composed of the same sound type, which can only be distinguished by the number of repeated elements. Several species of animals have proved to be able to acquire forms of communication through social learning: for instance
8100-425: The comparative method . The formal study of language is often considered to have started in India with Pāṇini , the 5th century BC grammarian who formulated 3,959 rules of Sanskrit morphology . However, Sumerian scribes already studied the differences between Sumerian and Akkadian grammar around 1900 BC. Subsequent grammatical traditions developed in all of the ancient cultures that adopted writing. In
8235-423: The mental faculty that allows humans to undertake linguistic behaviour: to learn languages and to produce and understand utterances. This definition stresses the universality of language to all humans, and it emphasizes the biological basis for the human capacity for language as a unique development of the human brain . Proponents of the view that the drive to language acquisition is innate in humans argue that this

#17327759569428370-524: The principle of compositionality to explain the relationship between meaningful parts and whole sentences. The principle of compositionality asserts that a sentence can be understood on the basis of the meaning of the parts of the sentence (i.e., words, morphemes) along with an understanding of its structure (i.e., syntax, logic). Further, syntactic propositions are arranged into discourse or narrative structures, which also encode meanings through pragmatics like temporal relations and pronominals. It
8505-503: The 17th century AD, the French Port-Royal Grammarians developed the idea that the grammars of all languages were a reflection of the universal basics of thought, and therefore that grammar was universal. In the 18th century, the first use of the comparative method by British philologist and expert on ancient India William Jones sparked the rise of comparative linguistics . The scientific study of language
8640-418: The 19th century discovered that two areas in the brain are crucially implicated in language processing. The first area is Wernicke's area , which is in the posterior section of the superior temporal gyrus in the dominant cerebral hemisphere. People with a lesion in this area of the brain develop receptive aphasia , a condition in which there is a major impairment of language comprehension, while speech retains

Russian speakers, who make an extra distinction between light and dark blue in their language, are better able to visually discriminate shades of blue. The Piraha , a tribe in Brazil , whose language has only terms like few and many instead of numerals, are not able to keep track of exact quantities. In one study German and Spanish speakers were asked to describe objects having opposite gender assignment in those two languages. The descriptions they gave differed in
9045-437: The amount of innate language, if language acquisition is a special faculty in the mind, and what the connection is between thought and language. There are three general perspectives on the issue of language learning. The first is the behaviorist perspective, which dictates that not only is the solid bulk of language learned, but it is learned via conditioning. The second is the hypothesis testing perspective , which understands
9180-435: The brain when it comes to language. Connectionist models emphasize the idea that a person's lexicon and their thoughts operate in a kind of distributed, associative network. Nativist models assert that there are specialized devices in the brain that are dedicated to language acquisition. Computation models emphasize the notion of a representational language of thought and the logic-like, computational processing that
9315-447: The brain, implanting a language organ in an otherwise primate brain." Though cautioning against taking this story literally, Chomsky insists that "it may be closer to reality than many other fairy tales that are told about evolutionary processes, including language." In March 2024, researchers reported that the beginnings of human language began about 1.6 million years ago. The study of language, linguistics , has been developing into
9450-400: The central figures involved in this development was the German philosopher Gottlob Frege , whose work on philosophical logic and the philosophy of language in the late 19th century influenced the work of 20th-century analytic philosophers Bertrand Russell and Ludwig Wittgenstein . The philosophy of language became so pervasive that for a time, in analytic philosophy circles, philosophy as
9585-401: The child's learning of syntactic rules and meanings to involve the postulation and testing of hypotheses, through the use of the general faculty of intelligence. The final candidate for explanation is the innatist perspective, which states that at least some of the syntactic settings are innate and hardwired, based on certain modules of the mind. There are varying notions of the structure of
9720-433: The common sentence is the lexical word , which is composed of nouns , verbs, and adjectives. A major question in the field – perhaps the single most important question for formalist and structuralist thinkers – is how the meaning of a sentence emerges from its parts. Many aspects of the problem of the composition of sentences are addressed in the field of linguistics of syntax . Philosophical semantics tends to focus on
9855-608: The communication of bees that can communicate the location of sources of nectar that are out of sight), the degree to which it is used in human language is also considered unique. Theories about the origin of language differ in regard to their basic assumptions about what language is. Some theories are based on the idea that language is so complex that one cannot imagine it simply appearing from nothing in its final form, but that it must have evolved from earlier pre-linguistic systems among our pre-human ancestors. These theories can be called continuity-based theories. The opposite viewpoint
9990-410: The complex grammar of human language. Human languages differ from animal communication systems in that they employ grammatical and semantic categories , such as noun and verb, present and past, which may be used to express exceedingly complex meanings. It is distinguished by the property of recursivity : for example, a noun phrase can contain another noun phrase (as in "[[the chimpanzee]'s lips]") or
10125-461: The degree of lip aperture and the placement of the tongue within the oral cavity. Vowels are called close when the lips are relatively closed, as in the pronunciation of the vowel [i] (English "ee"), or open when the lips are relatively open, as in the vowel [a] (English "ah"). If the tongue is located towards the back of the mouth, the quality changes, creating vowels such as [u] (English "oo"). The quality also changes depending on whether
10260-541: The development of language proper with anatomically modern Homo sapiens with the Upper Paleolithic revolution less than 100,000 years ago. Chomsky is one prominent proponent of a discontinuity-based theory of human language origins. He suggests that for scholars interested in the nature of language, "talk about the evolution of the language capacity is beside the point." Chomsky proposes that perhaps "some random mutation took place [...] and it reorganized
10395-487: The discreteness of the elements of language, meaning that the elements out of which linguistic signs are constructed are discrete units, e.g. sounds and words, that can be distinguished from each other and rearranged in different patterns; and the productivity of the linguistic system, meaning that the finite number of linguistic elements can be combined into a theoretically infinite number of combinations. Philosophy of language Philosophy of language investigates
10530-495: The distinctions between syntagm and paradigm , and the Langue-parole distinction , distinguishing language as an abstract system ( langue ), from language as a concrete manifestation of this system ( parole ). In the 1960s, Noam Chomsky formulated the generative theory of language . According to this theory, the most basic form of language is a set of syntactic rules that is universal for all humans and which underlies
10665-628: The early 19th century, the Danish philosopher Søren Kierkegaard insisted that language ought to play a larger role in Western philosophy . He argued that philosophy has not sufficiently focused on the role language plays in cognition and that future philosophy ought to proceed with a conscious focus on language: If the claim of philosophers to be unbiased were all it pretends to be, it would also have to take account of language and its whole significance in relation to speculative philosophy ... Language
10800-400: The effects of gendered language. It can also be used to study linguistic transparency (or speaking in an accessible manner), as well as performative utterances and the various tasks that language can perform (called "speech acts"). It also has applications to the study and interpretation of law, and helps give insight to the logical concept of the domain of discourse . Literary theory is
10935-413: The fact that humans use it to express themselves and to manipulate objects in their environment. Functional theories of grammar explain grammatical structures by their communicative functions, and understand the grammatical structures of language to be the result of an adaptive process by which grammar was "tailored" to serve the communicative needs of its users. This view of language is associated with
11070-613: The first serious proposals for codifying a mental language. The scholastics of the high medieval period, such as Ockham and John Duns Scotus , considered logic to be a scientia sermocinalis (science of language). The result of their studies was the elaboration of linguistic-philosophical notions whose complexity and subtlety has only recently come to be appreciated. Many of the most interesting problems of modern philosophy of language were anticipated by medieval thinkers. The phenomena of vagueness and ambiguity were analyzed intensely, and this led to an increasing interest in problems related to
11205-422: The formal theories of the generative school, functional theories of language propose that since language is fundamentally a tool, its structures are best analyzed and understood by reference to their functions. Formal theories of grammar seek to define the different elements of language and describe the way they relate to each other as systems of formal rules or operations, while functional theories seek to define
11340-409: The friendly aliens were called "leebish" and the hostile ones "grecious", while another quarter were told the opposite. For the rest, the aliens remained nameless. It was found that participants who were given names for the aliens learned to categorize the aliens far more quickly, reaching 80 per cent accuracy in less than half the time taken by those not told the names. By the end of the test, those told
11475-408: The functions performed by language and then relate them to the linguistic elements that carry them out. The framework of cognitive linguistics interprets language in terms of the concepts (which are sometimes universal, and sometimes specific to a particular language) which underlie its forms. Cognitive linguistics is primarily concerned with how the mind creates meaning through language. Speaking
11610-497: The gradual discovery of Chinese characters and Egyptian hieroglyphs ( Hieroglyphica ). This thought parallels the idea that there might be a universal language of music. European scholarship began to absorb the Indian linguistic tradition only from the mid-18th century, pioneered by Jean François Pons and Henry Thomas Colebrooke (the editio princeps of Varadarāja , a 17th-century Sanskrit grammarian, dating to 1849). In
11745-413: The grammar of single languages, theoretical linguistics develops theories on how best to conceptualize and define the nature of language based on data from the various extant human languages, sociolinguistics studies how languages are used for social purposes informing in turn the study of the social functions of language and grammatical description, neurolinguistics studies how language is processed in
11880-420: The grammars of all human languages. This set of rules is called Universal Grammar ; for Chomsky, describing it is the primary objective of the discipline of linguistics. Thus, he considered that the grammars of individual languages are only of importance to linguistics insofar as they allow us to deduce the universal underlying rules from which the observable linguistic variability is generated. In opposition to
12015-420: The history of their evolution can be reconstructed by comparing modern languages to determine which traits their ancestral languages must have had in order for the later developmental stages to occur. A group of languages that descend from a common ancestor is known as a language family ; in contrast, a language that has been demonstrated not to have any living or non-living relationship with another language
12150-445: The human brain and allows the experimental testing of theories, computational linguistics builds on theoretical and descriptive linguistics to construct computational models of language often aimed at processing natural language or at testing linguistic hypotheses, and historical linguistics relies on grammatical and lexical descriptions of languages to trace their individual histories and reconstruct trees of language families by using
12285-408: The lips are rounded as opposed to unrounded, creating distinctions such as that between [i] (unrounded front vowel such as English "ee") and [y] ( rounded front vowel such as German "ü"). Consonants are those sounds that have audible friction or closure at some point within the upper vocal tract. Consonant sounds vary by place of articulation, i.e. the place in the vocal tract where the airflow
12420-403: The meaning of sentences. Both expressive and receptive aphasia also affect the use of sign language, in analogous ways to how they affect speech, with expressive aphasia causing signers to sign slowly and with incorrect grammar, whereas a signer with receptive aphasia will sign fluently, but make little sense to others and have difficulties comprehending others' signs. This shows that the impairment
12555-462: The meanings of mental contents and states directly. Another tradition of philosophers has attempted to show that language and thought are coextensive – that there is no way of explaining one without the other. Donald Davidson, in his essay "Thought and Talk", argued that the notion of belief could only arise as a product of public linguistic interaction. Daniel Dennett holds a similar interpretationist view of propositional attitudes . To an extent,
12690-595: The methods available for reconstruction. Because language emerged in the early prehistory of man, before the existence of any written records, its early development has left no historical traces, and it is believed that no comparable processes can be observed today. Theories that stress continuity often look at animals to see if, for example, primates display any traits that can be seen as analogous to what pre-human language must have been like. Early human fossils can be inspected for traces of physical adaptation to language use or pre-linguistic forms of symbolic behaviour. Among
12825-424: The mind performs over them. Emergentist models focus on the notion that natural faculties are a complex system that emerge from simpler biological parts. Reductionist models attempt to explain higher-level mental processes in terms of the basic low-level neurophysiological activity. Firstly, this field of study seeks to better understand what speakers and listeners do with language in communication , and how it
12960-619: The mind. The main argument in favor of such a view is that the structure of thoughts and the structure of language seem to share a compositional, systematic character. Another argument is that it is difficult to explain how signs and symbols on paper can represent anything meaningful unless some sort of meaning is infused into them by the contents of the mind. One of the main arguments against is that such levels of language can lead to an infinite regress. In any case, many philosophers of mind and language, such as Ruth Millikan , Fred Dretske and Fodor, have recently turned their attention to explaining
13095-572: The mouth such as the l-sounds (called laterals , because the air flows along both sides of the tongue), and the r-sounds (called rhotics ). By using these speech organs, humans can produce hundreds of distinct sounds: some appear very often in the world's languages, whereas others are much more common in certain language families, language areas, or even specific to a single language. Human languages display considerable plasticity in their deployment of two fundamental modes: oral (speech and mouthing ) and manual (sign and gesture). For example, it
13230-401: The names could correctly categorize 88 per cent of aliens, compared to just 80 per cent for the rest. It was concluded that naming objects helps us categorize and memorize them. In another series of experiments, a group of people was asked to view furniture from an IKEA catalog. Half the time they were asked to label the object – whether it was a chair or lamp, for example – while the rest of
13365-488: The nature and origin of language go back to the ancient world. Greek philosophers such as Gorgias and Plato debated the relation between words, concepts and reality. Gorgias argued that language could represent neither the objective experience nor human experience, and that communication and truth were therefore impossible. Plato maintained that communication is possible because language represents ideas and concepts that exist independently of, and prior to, language. During
13500-455: The nature of language and the relations between language, language users, and the world. Investigations may include inquiry into the nature of meaning , intentionality , reference , the constitution of sentences, concepts, learning , and thought . Gottlob Frege and Bertrand Russell were pivotal figures in analytic philosophy's " linguistic turn ". These writers were followed by Ludwig Wittgenstein ( Tractatus Logico-Philosophicus ),
13635-479: The nature of synonymy , the origins of meaning itself, our apprehension of meaning, and the nature of composition (the question of how meaningful units of language are composed of smaller meaningful parts, and how the meaning of the whole is derived from the meaning of its parts). There have been several distinctive explanations of what a linguistic "meaning" is. Each has been associated with its own body of literature. Investigations into how language interacts with
13770-655: The only directly referential expressions are what he called "logically proper names". Logically proper names are such terms as I , now , here and other indexicals . He viewed proper names of the sort described above as "abbreviated definite descriptions " (see Theory of descriptions ). Hence Joseph R. Biden may be an abbreviation for "the current President of the United States and husband of Jill Biden". Definite descriptions are denoting phrases (see " On Denoting ") which are analyzed by Russell into existentially quantified logical constructions. Such phrases denote in
13905-414: The only gene that has definitely been implicated in language production is FOXP2 , which may cause a kind of congenital language disorder if affected by mutations . The brain is the coordinating center of all linguistic activity; it controls both the production of linguistic cognition and of meaning and the mechanics of speech production. Nonetheless, our knowledge of the neurological bases for language
14040-452: The opposite view. Around the turn of the 20th century, thinkers began to wonder about the role of language in shaping our experiences of the world – asking whether language simply reflects the objective structure of the world, or whether it creates concepts that in turn impose structure on our experience of the objective world. This led to the question of whether philosophical problems are really firstly linguistic problems. The resurgence of
14175-519: The original text of Shakespearean plays , while Wikibooks is dedicated either to original works, significantly altered versions of existing works, or annotations to original works. As of November 2024, there are Wikibooks sites for 121 languages of which 77 are active and 44 are closed. The active sites have 383,831 articles and the closed sites have 671 articles. There are 4,736,239 registered users of which 1,752 are recently active. The top ten Wikibooks language projects by mainspace article count: For
14310-400: The particular words that people use to achieve the proper emotional and rational effect in the listener, be it to persuade, provoke, endear, or teach. Some relevant applications of the field include the examination of propaganda and didacticism , the examination of the purposes of swearing and pejoratives (especially how it influences the behaviors of others, and defines relationships), or
14445-407: The philosopher of language. For instance, one of the major fields of sociology, symbolic interactionism , is based on the insight that human social organization is based almost entirely on the use of meanings. In consequence, any explanation of a social structure (like an institution ) would need to account for the shared meanings which create and sustain the structure. Rhetoric is the study of
14580-735: The philosophers Kant and Descartes, understands language to be largely innate , for example, in Chomsky 's theory of universal grammar , or American philosopher Jerry Fodor 's extreme innatist theory. These kinds of definitions are often applied in studies of language within a cognitive science framework and in neurolinguistics . Another definition sees language as a formal system of signs governed by grammatical rules of combination to communicate meaning. This definition stresses that human languages can be described as closed structural systems consisting of rules that relate particular signs to particular meanings. This structuralist view of language
14715-426: The philosophy of language, the view of linguistic meaning as residing in the logical relations between propositions and reality was developed by philosophers such as Alfred Tarski , Bertrand Russell , and other formal logicians . Yet another definition sees language as a system of communication that enables humans to exchange verbal or symbolic utterances. This definition stresses the social functions of language and
14850-540: The philosophy of language, the view of pragmatics as being central to language and meaning is often associated with Wittgenstein's later works and with ordinary language philosophers such as J. L. Austin , Paul Grice , John Searle , and W.O. Quine . A number of features, many of which were described by Charles Hockett and called design features set human language apart from communication used by non-human animals . Communication systems used by other animals such as bees or apes are closed systems that consist of
14985-423: The question of whether the names of things were determined by convention or by nature. He criticized conventionalism because it led to the bizarre consequence that anything can be conventionally denominated by any name. Hence, it cannot account for the correct or incorrect application of a name. He claimed that there was a natural correctness to names. To do this, he pointed out that compound words and phrases have
15120-404: The sense that there is an object that satisfies the description. However, such objects are not to be considered meaningful on their own, but have meaning only in the proposition expressed by the sentences of which they are a part. Hence, they are not directly referential in the same way as logically proper names, for Russell. On Frege's account, any referring expression has a sense as well as
15255-444: The set of utterances that can be produced from those rules. All languages rely on the process of semiosis to relate signs to particular meanings . Oral, manual and tactile languages contain a phonological system that governs how symbols are used to form sequences known as words or morphemes , and a syntactic system that governs how words and morphemes are combined to form phrases and utterances. The scientific study of language
15390-504: The sign itself and the thing to which it refers. This lektón was the meaning or sense of every term. The complete lektón of a sentence is what we would now call its proposition . Only propositions were considered truth-bearing —meaning they could be considered true or false—while sentences were simply their vehicles of expression. Different lektá could also express things besides propositions, such as commands, questions and exclamations. Medieval philosophers were greatly interested in
15525-413: The signs in human fossils that may suggest linguistic abilities are: the size of the brain relative to body mass, the presence of a larynx capable of advanced sound production and the nature of tools and other manufactured artifacts. It was mostly undisputed that pre-human australopithecines did not have communication systems significantly different from those found in great apes in general. However,
15660-519: The social conditions that give rise to, or are associated with, meanings and languages. Etymology (the study of the origins of words) and stylistics (philosophical argumentation over what makes "good grammar", relative to a particular language) are two other examples of fields that are taken to be metasemantic. Many separate (but related) fields have investigated the topic of linguistic convention within their own research paradigms. The presumptions that prop up each theoretical view are of interest to
15795-442: The space between two inhalations. Acoustically , these different segments are characterized by different formant structures, that are visible in a spectrogram of the recorded sound wave. Formants are the amplitude peaks in the frequency spectrum of a specific sound. Vowels are those sounds that have no audible friction caused by the narrowing or obstruction of some part of the upper vocal tract. They vary in quality according to
15930-710: The structures of language as having evolved to serve specific communicative and social functions. Language is processed in many different locations in the human brain , but especially in Broca's and Wernicke's areas . Humans acquire language through social interaction in early childhood, and children generally speak fluently by approximately three years old. Language and culture are codependent. Therefore, in addition to its strictly communicative uses, language has social uses such as signifying group identity , social stratification , as well as use for social grooming and entertainment . Languages evolve and diversify over time, and
16065-550: The study of language in pragmatic , cognitive , and interactive frameworks, as well as in sociolinguistics and linguistic anthropology . Functionalist theories tend to study grammar as dynamic phenomena, as structures that are always in the process of changing as they are employed by their speakers. This view places importance on the study of linguistic typology , or the classification of languages according to structural features, as processes of grammaticalization tend to follow trajectories that are partly dependent on typology. In
16200-584: The study of meaning at all. Noam Chomsky proposed that the study of language could be done in terms of the I-Language, or internal language of persons. If this is so, then it undermines the pursuit of explanations in terms of conventions, and relegates such explanations to the domain of metasemantics . Metasemantics is a term used by philosopher of language Robert Stainton to describe all those fields that attempt to explain how semantic facts arise. One fruitful source of research involves investigation into
16335-428: The subtleties of language and its usage. For many scholastics , this interest was provoked by the necessity of translating Greek texts into Latin . There were several noteworthy philosophers of language in the medieval period. According to Peter J. King, (although this has been disputed), Peter Abelard anticipated the modern theories of reference . Also, William of Ockham 's Summa Logicae brought forward one of
16470-493: The theoretical underpinnings to cognitive semantics (including the notion of semantic framing ) suggest the influence of language upon thought. However, the same tradition views meaning and grammar as a function of conceptualization, making it difficult to assess in any straightforward way. Some thinkers, like the ancient sophist Gorgias , have questioned whether or not language was capable of capturing thought at all. ...speech can never exactly represent perceptibles, since it
16605-571: The thought that its embedding sentence expresses. Senses determine reference and are also the modes of presentation of the objects to which expressions refer. Referents are the objects in the world that words pick out. The senses of sentences are thoughts, while their referents are truth values (true or false). The referents of sentences embedded in propositional attitude ascriptions and other opaque contexts are their usual senses. Bertrand Russell , in his later writings and for reasons related to his theory of acquaintance in epistemology , held that
16740-507: The time they had to say whether or not they liked it. It was found that when asked to label items, people were later less likely to recall the specific details of products, such as whether a chair had arms or not. It was concluded that labeling objects helps our minds build a prototype of the typical object in the group at the expense of individual features. A common claim is that language is governed by social conventions. Questions inevitably arise on surrounding topics. One question regards what
16875-418: The use of syncategorematic words such as and , or , not , if , and every . The study of categorematic words (or terms ) and their properties was also developed greatly. One of the major developments of the scholastics in this area was the doctrine of the suppositio . The suppositio of a term is the interpretation that is given of it in a specific context. It can be proper or improper (as when it
17010-516: The vase" even for accidents. However, Spanish or Japanese speakers would be more likely to say "the vase broke itself". In studies conducted by Caitlin Fausey at Stanford University speakers of English, Spanish and Japanese watched videos of two people popping balloons, breaking eggs and spilling drinks either intentionally or accidentally. Later everyone was asked whether they could remember who did what. Spanish and Japanese speakers did not remember
17145-452: The view that language plays a significant role in the creation and circulation of concepts, and that the study of philosophy is essentially the study of language, is associated with what has been called the linguistic turn and philosophers such as Wittgenstein in 20th-century philosophy. These debates about language in relation to meaning and reference, cognition and consciousness remain active today. One definition sees language primarily as
17280-449: The visual modality, and braille writing uses the tactile modality. Human language is unusual in being able to refer to abstract concepts and to imagined or hypothetical events as well as events that took place in the past or may happen in the future. This ability to refer to events that are not at the same time or place as the speech event is called displacement , and while some animal communication systems can use displacement (such as
17415-418: The vocal cords are set in vibration by airflow during the production of the sound. Voicing is what separates English [s] in bus ( unvoiced sibilant ) from [z] in buzz ( voiced sibilant ). Some speech sounds, both vowels and consonants, involve release of air flow through the nasal cavity, and these are called nasals or nasalized sounds. Other sounds are defined by the way the tongue moves within
17550-418: The world are called theories of reference . Gottlob Frege was an advocate of a mediated reference theory . Frege divided the semantic content of every expression, including sentences, into two components: sense and reference . The sense of a sentence is the thought that it expresses. Such a thought is abstract, universal and objective. The sense of any sub-sentential expression consists in its contribution to
17685-636: Was analytically prior to thought. Philosopher Michael Dummett is also a proponent of the "language-first" viewpoint. The stark opposite to the Sapir–Whorf position is the notion that thought (or, more broadly, mental content) has priority over language. The "knowledge-first" position can be found, for instance, in the work of Paul Grice . Further, this view is closely associated with Jerry Fodor and his language of thought hypothesis. According to his argument, spoken and written language derive their intentionality and meaning from an internal language encoded in
17820-561: Was broadened from Indo-European to language in general by Wilhelm von Humboldt . Early in the 20th century, Ferdinand de Saussure introduced the idea of language as a static system of interconnected units, defined through the oppositions between them. By introducing a distinction between diachronic and synchronic analyses of language, he laid the foundation of the modern discipline of linguistics. Saussure also introduced several basic dimensions of linguistic analysis that are still fundamental in many contemporary linguistic theories, such as
17955-475: Was criticized in Saul Kripke 's Naming and Necessity . Kripke put forth what has come to be known as "the modal argument" (or "argument from rigidity"). Consider the name Aristotle and the descriptions "the greatest student of Plato", "the founder of logic" and "the teacher of Alexander". Aristotle obviously satisfies all of the descriptions (and many of the others we commonly associate with him), but it
18090-433: Was first introduced by Ferdinand de Saussure , and his structuralism remains foundational for many approaches to language. Some proponents of Saussure's view of language have advocated a formal approach which studies language structure by identifying its basic elements and then by presenting a formal account of the rules according to which the elements combine in order to form words and sentences. The main proponent of such
18225-403: Was held. In another example, the ritual language Damin had a heavily reduced oral vocabulary of only a few hundred words, each of which was very general in meaning, but which were supplemented by gesture for greater precision (e.g., the single word for fish, l*i , was accompanied by a gesture to indicate the kind of fish). Secondary modes of language, by which a fundamental mode is conveyed in
