106-485: These phrases are similar, but may be used for different degrees of indeterminacy: Other similar phrases sometimes used to convey the same meaning, and using the same abbreviations , include "to be ascertained", "to be arranged", "to be adjudicated", and "to be done". Use of the abbreviation "TBA" is formally reported in a reference work at least as early as 1955, and "TBD" is similarly reported as early as 1967. These various placeholder terms are often used to indicate to

212-493: A different context. For example, the reference of the word here depends on the location in which it is used. A closely related approach is possible world semantics, which allows expressions to refer not only to entities in the actual world but also to entities in other possible worlds. According to this view, expressions like the first man to run a four-minute mile refer to different persons in different worlds. This view can also be used to analyze sentences that talk about what

318-440: A different sense have the same referent. For instance, the sentence "the morning star is the evening star" is informative and people can learn something from it. The sentence "the morning star is the morning star", by contrast, is an uninformative tautology since the expressions are identical not only on the level of reference but also on the level of sense. Compositionality is a key aspect of how languages construct meaning. It

424-443: A few examples, there is Aldi , from Theo Albrecht , the name of its founder, followed by discount ; Haribo , from Hans Riegel , the name of its founder, followed by Bonn , the town of its head office; and Adidas , from Adolf "Adi" Dassler , the nickname of its founder followed by his surname. Semantic Semantics is the study of linguistic meaning . It examines what meaning is, how words get their meaning, and how

530-413: A more complex meaning structure. In the expression "Beethoven likes Schubert", the verb like connects a liker to the object of their liking. Other sentence parts modify meaning rather than form new connections. For instance, the adjective red modifies the color of another entity in the expression red car . A further compositional device is variable binding, which is used to determine the reference of

636-414: A particular language. Some semanticists also include the study of lexical units other than words in the field of lexical semantics. Compound expressions like being under the weather have a non-literal meaning that acts as a unit and is not a direct function of its parts. Another topic concerns the meaning of morphemes that make up words, for instance, how negative prefixes like in- and dis- affect

742-413: A particular language. The same symbol may refer to one object in one language, to another object in a different language, and to no object in another language. Many other concepts are used to describe semantic phenomena. The semantic role of an expression is the function it fulfills in a sentence. In the sentence "the boy kicked the ball", the boy has the role of the agent who performs an action. The ball

848-402: A pending pool of as-yet unspecified mortgages, which will be specified at a given delivery date. This usage has existed at least since the 1980s. Abbreviation An abbreviation (from Latin brevis , meaning "short" ) is a shortened form of a word or phrase, by any method including shortening, contraction , initialism (which includes acronym) or crasis . An abbreviation may be

954-480: A person's name, such as Migjeni —an abbreviation from his original name ( Millosh Gjergj Nikolla ) a famous Albanian poet and writer—or ASDRENI ( Aleksander Stavre Drenova ), another famous Albanian poet. Other such names which are used commonly in recent decades are GETOAR, composed from Gegeria + Tosks (representing the two main dialects of the Albanian language, Gegë and Toskë), and Arbanon —which

1060-555: A plural of an initialization without an apostrophe can also be used for a number, or a letter. Examples: For units of measure, the same form is used for both singular and plural. Examples: When an abbreviation contains more than one period, Hart's Rules recommends putting the s after the final one. Examples: However, the same plurals may be rendered less formally as: According to Hart's Rules , an apostrophe may be used in rare cases where clarity calls for it, for example when letters or symbols are referred to as objects. However,

1166-427: A shortened form of a word with a trailing period. For example: etcetera is usually abbreviated etc. and abbreviation is sometimes abbreviated abbr. , abbrv. , or abbrev. . But sometimes the trailing period is not used for such shortened forms. A contraction is an abbreviation formed by replacing letters with an apostrophe. Examples include I'm for I am and li'l for little . An initialism or acronym

1272-557: A single letter and was originally spelled with lower case letters then there is no need for capitalization. However, when abbreviating a phrase where only the first letter of each word is taken, then all letters should be capitalized, as in YTD for year-to-date , PCB for printed circuit board and FYI for for your information . However, see the following section regarding abbreviations that have become common vocabulary: these are no longer written with capital letters. A period (a.k.a. full stop)

1378-445: A speaker remains silent on a certain topic. A closely related distinction by the semiotician Charles W. Morris holds that semantics studies the relation between words and the world, pragmatics examines the relation between words and users, and syntax focuses on the relation between different words. Semantics is related to etymology , which studies how words and their meanings changed in the course of history. Another connected field

1484-438: A strict distinction between meaning and syntax and by relying on various formal devices to explore the relation between meaning and cognition. Computational semantics examines how the meaning of natural language expressions can be represented and processed on computers. It often relies on the insights of formal semantics and applies them to problems that can be computationally solved. Some of its key problems include computing

1590-459: A strong sense, the principle of compositionality states that the meaning of a complex expression is not just affected by its parts and how they are combined but fully determined this way. It is controversial whether this claim is correct or whether additional aspects influence meaning. For example, context may affect the meaning of expressions; idioms like " kick the bucket " carry figurative or non-literal meanings that are not directly reducible to

1696-517: A symbol such as "km" for " kilometre ". In the International System of Units (SI) manual the word "symbol" is used consistently to define the shorthand used to represent the various SI units of measure. The manual also defines the way in which units should be written , the principal rules being: A syllabic abbreviation is usually formed from the initial syllables of several words, such as Interpol = International + police . It

1802-508: A term. For example, the last part of the expression "the woman who likes Beethoven" specifies which woman is meant. Parse trees can be used to show the underlying hierarchy employed to combine the different parts. Various grammatical devices, like the gerund form, also contribute to meaning and are studied by grammatical semantics. Formal semantics uses formal tools from logic and mathematics to analyze meaning in natural languages. It aims to develop precise logical formalisms to clarify

1908-407: A text that come before and after it. Context affects the meaning of various expressions, like the deictic expression here and the anaphoric expression she . A syntactic environment is extensional or transparent if it is always possible to exchange expressions with the same reference without affecting the truth value of the sentence. For example, the environment of the sentence "the number 8

2014-457: A uniform signifying rank , and the presence of vultures indicating a nearby animal carcass. Semantics further contrasts with pragmatics , which is interested in how people use language in communication. An expression like "That's what I'm talking about" can mean many things depending on who says it and in what situation. Semantics is interested in the possible meanings of expressions: what they can and cannot mean in general. In this regard, it

2120-427: A word means by looking at its letters and one needs to consult a dictionary instead. Compositionality is often used to explain how people can formulate and understand an almost infinite number of meanings even though the amount of words and cognitive resources is finite. Many sentences that people read are sentences that they have never seen before and they are nonetheless able to understand them. When interpreted in

2226-484: Is hermeneutics , which is the art or science of interpretation and is concerned with the right methodology of interpreting text in general and scripture in particular. Metasemantics examines the metaphysical foundations of meaning and aims to explain where it comes from or how it arises. The word semantics originated from the Ancient Greek adjective semantikos , meaning 'relating to signs', which

2332-400: Is 8. Semanticists commonly distinguish the language they study, called object language, from the language they use to express their findings, called metalanguage . When a professor uses Japanese to teach their student how to interpret the language of first-order logic then the language of first-order logic is the object language and Japanese is the metalanguage. The same language may occupy

2438-529: Is a derivative of sēmeion , the noun for ' sign '. It was initially used for medical symptoms and only later acquired its wider meaning regarding any type of sign, including linguistic signs. The word semantics entered the English language from the French term semantique , which the linguist Michel Bréal first introduced at the end of the 19th century. Semantics studies meaning in language, which

2544-568: Is a syllabic abbreviation of Commonwealth and (Thomas) Edison . Sections of California are also often colloquially syllabically abbreviated, as in NorCal (Northern California), CenCal (Central California), and SoCal (Southern California). Additionally, in the context of Los Angeles, the syllabic abbreviation SoHo (Southern Hollywood) refers to the southern portion of the Hollywood neighborhood. Partially syllabic abbreviations are preferred by

2650-478: Is a variant of the acronym. Syllabic abbreviations are usually written using lower case , sometimes starting with a capital letter , and are always pronounced as words rather than letter by letter. Syllabic abbreviations should be distinguished from portmanteaus , which combine two words without necessarily taking whole syllables from each. Syllabic abbreviations are not widely used in English. Some UK government agencies such as Ofcom (Office of Communications) and

2756-526: Is an abbreviation consisting of the initial letter of a sequence of words without other punctuation. For example, FBI ( /ˌɛf.biːˈaɪ/ ), USA ( /ˌjuː.ɛsˈeɪ/ ), IBM ( /ˌaɪ.biːˈɛm/ ), BBC ( /ˌbiː.biːˈsiː/ ). When initialism is used as the preferred term, acronym refers more specifically to when the abbreviation is pronounced as a word rather than as separate letters; examples include SWAT and NASA . Initialisms, contractions and crasis share some semantic and phonetic functions, and are connected by

2862-777: Is an alternative way used to describe all Albanian lands. Syllabic abbreviations were and are common in German ; much like acronyms in English, they have a distinctly modern connotation, although contrary to popular belief, many date back to before 1933 , if not the end of the Great War . Kriminalpolizei , literally criminal police but idiomatically the Criminal Investigation Department of any German police force, begat KriPo (variously capitalised), and likewise Schutzpolizei ( protection police or uniform department ) begat SchuPo . Along

2968-577: Is and how it arises. It investigates how expressions are built up from different layers of constituents, like morphemes , words , clauses , sentences , and texts , and how the meanings of the constituents affect one another. Semantics can focus on a specific language, like English, but in its widest sense, it investigates meaning structures relevant to all languages. As a descriptive discipline, it aims to determine how meaning works without prescribing what meaning people should associate with particular expressions. Some of its key questions are "How do

3074-418: Is controversy as to which should be used. One generally accepted rule is to be consistent in a body of work. To this end, publishers may express their preferences in a style guide . Some controversies that arise are described below. If the original word was capitalized then the first letter of its abbreviation should retain the capital, for example Lev. for Leviticus . When a word is abbreviated to more than

3180-426: Is created through the combination of expressions belonging to different syntactic categories. Dynamic semantics is a subfield of formal semantics that focuses on how information grows over time. According to it, "meaning is context change potential": the meaning of a sentence is not given by the information it contains but by the information change it brings about relative to a context. Cognitive semantics studies

3286-445: Is described but an experience takes place, like when a girl sees a bird. In this case, the girl has the role of the experiencer. Other common semantic roles are location, source, goal, beneficiary, and stimulus. Lexical relations describe how words stand to one another. Two words are synonyms if they share the same or a very similar meaning, like car and automobile or buy and purchase . Antonyms have opposite meanings, such as

3392-408: Is even" is extensional because replacing the expression the number 8 with the number of planets in the solar system does not change its truth value. For intensional or opaque contexts , this type of substitution is not always possible. For instance, the embedded clause in "Paco believes that the number 8 is even" is intensional since Paco may not know that the number of planets in the solar system

3498-514: Is interested in how meanings evolve and change because of cultural phenomena associated with politics , religion, and customs . For example, address practices encode cultural values and social hierarchies, as in the difference of politeness of expressions like tu and usted in Spanish or du and Sie in German in contrast to English, which lacks these distinctions and uses

3604-454: Is limited to the meaning of linguistic expressions. It concerns how signs are interpreted and what information they contain. An example is the meaning of words provided in dictionary definitions by giving synonymous expressions or paraphrases, like defining the meaning of the term ram as adult male sheep . There are many forms of non-linguistic meaning that are not examined by semantics. Actions and policies can have meaning in relation to

3710-446: Is possible or what is necessary: possibility is what is true in some possible worlds while necessity is what is true in all possible worlds. Ideational theories, also called mentalist theories, are not primarily interested in the reference of expressions and instead explain meaning in terms of the mental states of language users. One historically influential approach articulated by John Locke holds that expressions stand for ideas in

3816-430: Is sometimes defined as the study of context-independent meaning. Pragmatics examines which of these possible meanings is relevant in a particular case. In contrast to semantics, it is interested in actual performance rather than in the general linguistic competence underlying this performance. This includes the topic of additional meaning that can be inferred even though it is not literally expressed, like what it means if

3922-444: Is sometimes divided into two complementary approaches: semasiology and onomasiology . Semasiology starts from words and examines what their meaning is. It is interested in whether words have one or several meanings and how those meanings are related to one another. Instead of going from word to meaning, onomasiology goes from meaning to word. It starts with a concept and examines what names this concept has or how it can be expressed in

4028-504: Is sometimes understood as a mental phenomenon that helps people identify the objects to which an expression refers. Some semanticists focus primarily on sense or primarily on reference in their analysis of meaning. To grasp the full meaning of an expression, it is usually necessary to understand both to what entities in the world it refers and how it describes them. The distinction between sense and reference can explain identity statements , which can be used to show how two expressions with

4134-695: Is sometimes used to signify abbreviation, but opinion is divided as to when and if this convention is best practice. According to Hart's Rules , a word shortened by dropping letters from the end terminates with a period, whereas a word shorted by dropping letters from the middle does not. Fowler's Modern English Usage says a period is used for both of these shortened forms, but recommends against this practice: advising it only for end-shortened words and lower-case initialisms; not for middle-shortened words and upper-case initialisms. Some British style guides, such as for The Guardian and The Economist , disallow periods for all abbreviations. In American English ,

4240-413: Is the branch of semantics that studies word meaning . It examines whether words have one or several meanings and in what lexical relations they stand to one another. Phrasal semantics studies the meaning of sentences by exploring the phenomenon of compositionality or how new meanings can be created by arranging words. Formal semantics relies on logic and mathematics to provide precise frameworks of

4346-416: Is the idea that the meaning of a complex expression is a function of the meanings of its parts. It is possible to understand the meaning of the sentence "Zuzana owns a dog" by understanding what the words Zuzana , owns , a and dog mean and how they are combined. In this regard, the meaning of complex expressions like sentences is different from word meaning since it is normally not possible to deduce what

4452-419: Is the object to which the expression points. The sense of an expression is the way in which it refers to that object or how the object is interpreted. For example, the expressions morning star and evening star refer to the same planet, just like the expressions 2 + 2 and 3 + 1 refer to the same number. The meanings of these expressions differ not on the level of reference but on the level of sense. Sense

4558-404: Is the theme or patient of this action as something that does not act itself but is involved in or affected by the action. The same entity can be both agent and patient, like when someone cuts themselves. An entity has the semantic role of an instrument if it is used to perform the action, for instance, when cutting something with a knife then the knife is the instrument. For some sentences, no action

4664-404: Is true. Many related disciplines investigate language and meaning. Semantics contrasts with other subfields of linguistics focused on distinct aspects of language. Phonology studies the different types of sounds used in languages and how sounds are connected to form words while syntax examines the rules that dictate how to arrange words to create sentences. These divisions are reflected in

4770-584: Is typically US . There are multiple ways to pluralize an abbreviation. Sometimes this accomplished by adding an apostrophe and an s ( 's ), as in "two PC's have broken screens". But, some find this confusing since the notation can indicate possessive case . And, this style is deprecated by many style guides. For instance, Kate Turabian , writing about style in academic writings, allows for an apostrophe to form plural acronyms "only when an abbreviation contains internal periods or both capital and lowercase letters". For example, "DVDs" and "URLs" and "Ph.D.'s", while

4876-450: Is used if the different meanings are closely related to one another, like the meanings of the word head , which can refer to the topmost part of the human body or the top-ranking person in an organization. The meaning of words can often be subdivided into meaning components called semantic features . The word horse has the semantic feature animate but lacks the semantic feature human . It may not always be possible to fully reconstruct

4982-518: The British Board of Film Classification (BBFC) requires the use of "tbc" (meaning "to be classified") for products that have been submitted to the BBFC and are awaiting final rating. "TBA" (meaning "to be announced") is also used to describe a specific type of simple mortgage investment, the forward mortgage-backed security . This is used to indicate that the investor is acquiring some portion of

5088-576: The Modern Language Association explicitly says, "do not use an apostrophe to form the plural of an abbreviation". Also, the American Psychological Association specifically says, "without an apostrophe". However, the 1999 style guide for The New York Times states that the addition of an apostrophe is necessary when pluralizing all abbreviations, preferring "PC's, TV's and VCR's". Forming

5194-690: The Old English poem Beowulf used many abbreviations, for example the Tironian et ( ⁊ ) or & for and , and y for since , so that "not much space is wasted". The standardisation of English in the 15th through 17th centuries included a growth in the use of such abbreviations. At first, abbreviations were sometimes represented with various suspension signs, not only periods. For example, sequences like ⟨er⟩ were replaced with ⟨ɔ⟩ , as in mastɔ for master and exacɔbate for exacerbate . While this may seem trivial, it

5300-399: The use theory , and inferentialist semantics . The study of semantic phenomena began during antiquity but was not recognized as an independent field of inquiry until the 19th century. Semantics is relevant to the fields of formal logic, computer science , and psychology . Semantics is the study of meaning in languages . It is a systematic inquiry that examines what linguistic meaning

5406-598: The vocabulary as a whole. This includes the study of lexical relations between words, such as whether two terms are synonyms or antonyms. Lexical semantics categorizes words based on semantic features they share and groups them into semantic fields unified by a common subject. This information is used to create taxonomies to organize lexical knowledge, for example, by distinguishing between physical and abstract entities and subdividing physical entities into stuff and individuated entities . Further topics of interest are polysemy, ambiguity, and vagueness . Lexical semantics

5512-459: The 1990s led to a marked rise in colloquial abbreviation. This was due largely to increasing popularity of textual communication services such as instant and text messaging. The original SMS supported message lengths of 160 characters at most (using the GSM 03.38 character set), for instance. This brevity gave rise to an informal abbreviation scheme sometimes called Textese , with which 10% or more of

5618-661: The 20th century. The contractions in Newspeak are supposed to have a political function by virtue of their abbreviated structure itself: nice sounding and easily pronounceable, their purpose is to mask all ideological content from the speaker. A more recent syllabic abbreviation has emerged with the disease COVID-19 (Corona Virus Disease 2019) caused by the Severe acute respiratory syndrome coronavirus 2 (itself frequently abbreviated to SARS-CoV-2 , partly an initialism). In Albanian, syllabic acronyms are sometimes used for composing

5724-768: The US Navy, as they increase readability amidst the large number of initialisms that would otherwise have to fit into the same acronyms. Hence DESRON 6 is used (in the full capital form) to mean "Destroyer Squadron 6", while COMNAVAIRLANT would be "Commander, Naval Air Force (in the) Atlantic". Syllabic abbreviations are a prominent feature of Newspeak , the fictional language of George Orwell 's dystopian novel Nineteen Eighty-Four . The political contractions of Newspeak— Ingsoc (English Socialism), Minitrue (Ministry of Truth), Miniplenty ( Ministry of Plenty )—are described by Orwell as similar to real examples of German ( see below ) and Russian ( see below ) contractions in

5830-460: The apostrophe can be dispensed with if the items are set in italics or quotes: In Latin, and continuing to the derivative forms in European languages as well as English, single-letter abbreviations had the plural being a doubling of the letter for note-taking. Most of these deal with writing and publishing. A few longer abbreviations use this as well. Publications based in the U.S. tend to follow

5936-420: The cognitive conceptual structures of humans are universal or relative to their linguistic background. Another research topic concerns the psychological processes involved in the application of grammar. Other investigated phenomena include categorization, which is understood as a cognitive heuristic to avoid information overload by regarding different entities in the same way, and embodiment , which concerns how

6042-454: The conditions under which it would be true. This can happen even if one does not know whether the conditions are fulfilled. The semiotic triangle , also called the triangle of meaning, is a model used to explain the relation between language, language users, and the world, represented in the model as Symbol , Thought or Reference , and Referent . The symbol is a linguistic signifier , either in its spoken or written form. The central idea of

6148-408: The context, like the deictic terms here and I . To avoid these problems, referential theories often introduce additional devices. Some identify meaning not directly with objects but with functions that point to objects. This additional level has the advantage of taking the context of an expression into account since the same expression may point to one object in one context and to another object in

6254-478: The contrast between alive and dead or fast and slow . One term is a hyponym of another term if the meaning of the first term is included in the meaning of the second term. For example, ant is a hyponym of insect . A prototype is a hyponym that has characteristic features of the type it belongs to. A robin is a prototype of a bird but a penguin is not. Two words with the same pronunciation are homophones like flour and flower , while two words with

6360-399: The corresponding physical object. The relation is only established indirectly through the mind of the language user. When they see the symbol, it evokes a mental image or a concept, which establishes the connection to the physical object. This process is only possible if the language user learned the meaning of the symbol before. The meaning of a specific symbol is governed by the conventions of

6466-541: The fact that it is possible to master some aspects of a language while lacking others, like when a person knows how to pronounce a word without knowing its meaning. As a subfield of semiotics, semantics has a more narrow focus on meaning in language while semiotics studies both linguistic and non-linguistic signs. Semiotics investigates additional topics like the meaning of non-verbal communication , conventional symbols , and natural signs independent of human interaction. Examples include nodding to signal agreement, stripes on

For example, the profile of the word hypotenuse is a straight line while the base is a right-angled triangle of which the hypotenuse forms a part. Cognitive semantics further compares the conceptual patterns and linguistic typologies across languages and considers to what extent

New York City has various neighborhoods named by syllabic abbreviation, such as Tribeca (Triangle below Canal Street) and SoHo (South of Houston Street).

6784-456: The globally popular term OK generally credited as a remnant of its influence. Over the years, however, the lack of convention in some style guides has made it difficult to determine which two-word abbreviations should be abbreviated with periods and which should not. This question is considered below. Widespread use of electronic communication through mobile phones and the Internet during

6890-408: The goal they serve. Fields like religion and spirituality are interested in the meaning of life , which is about finding a purpose in life or the significance of existence in general. Linguistic meaning can be analyzed on different levels. Word meaning is studied by lexical semantics and investigates the denotation of individual words. It is often related to concepts of entities, like how

6996-453: The language user's bodily experience affects the meaning of expressions. Frame semantics is an important subfield of cognitive semantics. Its central idea is that the meaning of terms cannot be understood in isolation from each other but needs to be analyzed on the background of the conceptual structures they depend on. These structures are made explicit in terms of semantic frames. For example, words like bride, groom, and honeymoon evoke in

7102-400: The locked-in team. In government and business, the terms may be used to indicate that a vacant organizational position is expected to be filled, or conversely that a particular individual will be employed in an as-yet-uncreated position. In program guide listings, both paper and electronic, the term indicates that the program to be aired by a television station or channel will be announced in

7208-487: The meaning of a complex expression depends on its parts. Part of this process involves the distinction between sense and reference . Sense is given by the ideas and concepts associated with an expression while reference is the object to which an expression points. Semantics contrasts with syntax , which studies the rules that dictate how to create grammatically correct sentences, and pragmatics , which investigates how people use language in communication. Lexical semantics

7314-457: The meaning of a word by identifying all its semantic features. A semantic or lexical field is a group of words that are all related to the same activity or subject. For instance, the semantic field of cooking includes words like bake , boil , spice , and pan . The context of an expression refers to the situation or circumstances in which it is used and includes time, location, speaker, and audience. It also encompasses other passages in

7420-446: The meaning of an expression is the part of reality to which it points. Ideational theories identify meaning with mental states like the ideas that an expression evokes in the minds of language users. According to causal theories, meaning is determined by causes and effects, which behaviorist semantics analyzes in terms of stimulus and response. Further theories of meaning include truth-conditional semantics , verificationist theories,

7526-492: The meaning of complex expressions by analyzing their parts, handling ambiguity, vagueness, and context-dependence, and using the extracted information in automatic reasoning . It forms part of computational linguistics , artificial intelligence , and cognitive science . Its applications include machine learning and machine translation . Cultural semantics studies the relation between linguistic meaning and culture. It compares conceptual structures in different languages and

7632-407: The meaning of particular expressions, like the semantics of the word fairy . As a field of inquiry, semantics has both an internal and an external side. The internal side is interested in the connection between words and the mental phenomena they evoke, like ideas and conceptual representations. The external side examines how words refer to objects in the world and under what conditions a sentence

7738-655: The meaning of the name George Washington is the person with this name. General terms refer not to a single entity but to the set of objects to which this term applies. In this regard, the meaning of the term cat is the set of all cats. Similarly, verbs usually refer to classes of actions or events and adjectives refer to properties of individuals and events. Simple referential theories face problems for meaningful expressions that have no clear referent. Names like Pegasus and Santa Claus have meaning even though they do not point to existing entities. Other difficulties concern cases in which different expressions are about

7844-421: The meaning of the words they are part of, as in inanimate and dishonest . Phrasal semantics studies the meaning of sentences. It relies on the principle of compositionality to explore how the meaning of complex expressions arises from the combination of their parts. The different parts can be analyzed as subject , predicate , or argument . The subject of a sentence usually refers to a specific entity while

7950-413: The meanings of their parts. Truth is a property of statements that accurately present the world and true statements are in accord with reality . Whether a statement is true usually depends on the relation between the statement and the rest of the world. The truth conditions of a statement are the way the world needs to be for the statement to be true. For example, it belongs to the truth conditions of

8056-492: The meanings of words combine to create the meanings of sentences?", "How do meanings relate to the minds of language users, and to the things words refer to?", and "What is the connection between what a word means, and the contexts in which it is used?". The main disciplines engaged in semantics are linguistics , semiotics , and philosophy . Besides its meaning as a field of inquiry, semantics can also refer to theories within this field, like truth-conditional semantics , and to

8162-467: The mind the frame of marriage. Conceptual semantics shares with cognitive semantics the idea of studying linguistic meaning from a psychological perspective by examining how humans conceptualize and experience the world. It holds that meaning is not about the objects to which expressions refer but about the cognitive structure of human concepts that connect thought, perception, and action. Conceptual semantics differs from cognitive semantics by introducing

8268-448: The model is that there is no direct relation between a linguistic expression and what it refers to, as was assumed by earlier dyadic models. This is expressed in the diagram by the dotted line between symbol and referent. The model holds instead that the relation between the two is mediated through a third component. For example, the term apple stands for a type of fruit but there is no direct connection between this string of letters and

8374-403: The near future, a last-second decision to remove a program or film where the content to be aired in its place cannot be updated on short notice by the listings provider, or that a program's airing (or delay to another time) depends on the continuation of a sports playoff series, which usually applies between the fifth and seventh matches or games of a best-of-seven series. The age rating system of

8480-487: The period is usually included regardless of whether or not it is a contraction, e.g. Dr. or Mrs. . In some cases, periods are optional, as in either US or U.S. for United States , EU or E.U. for European Union , and UN or U.N. for United Nations . There are some house styles, however—American ones included—that remove the periods from almost all abbreviations. For example: Acronyms that were originally capitalized (with or without periods) but have since entered

8586-564: The predicate describes a feature of the subject or an event in which the subject participates. Arguments provide additional information to complete the predicate. For example, in the sentence "Mary hit the ball", Mary is the subject, hit is the predicate, and the ball is an argument. A more fine-grained categorization distinguishes between different semantic roles of words, such as agent, patient, theme, location, source, and goal. Verbs usually function as predicates and often help to establish connections between different expressions to form

8692-401: The problem of meaning from a psychological perspective or how the mind of the language user affects meaning. As a subdiscipline of cognitive linguistics , it sees language as a wide cognitive ability that is closely related to the conceptual structures used to understand and represent the world. Cognitive semanticists do not draw a sharp distinction between linguistic knowledge and knowledge of

8798-448: The project may also be designated as " untitled " pending that determination. The terms are also used in sports schedules, particularly where one team has locked in a position in a playoff schedule , but its opponent cannot yet be determined because several teams may qualify for the spot depending on their remaining wins or losses for the season, or because other teams have not yet competed in playoff games that will determine who will face

8904-601: The pronoun you in either case. Closely related fields are intercultural semantics, cross-cultural semantics, and comparative semantics. Pragmatic semantics studies how the meaning of an expression is shaped by the situation in which it is used. It is based on the idea that communicative meaning is usually context-sensitive and depends on who participates in the exchange, what information they share, and what their intentions and background assumptions are. It focuses on communicative actions, of which linguistic expressions only form one part. Some theorists include these topics within

9010-497: The public meaning that expressions have, like the meaning found in general dictionary definitions. Speaker meaning, by contrast, is the private or subjective meaning that individuals associate with expressions. It can diverge from the literal meaning, like when a person associates the word needle with pain or drugs. Meaning is often analyzed in terms of sense and reference , also referred to as intension and extension or connotation and denotation . The referent of an expression

9116-400: The public that a vacant position in a lineup of speakers , musicians , or other performers remains to be filled. The terms also frequently indicate that a creative work, such as an album or film, is forthcoming but that the date of release is not yet known. If the forthcoming project is not yet named, these placeholders may be used to indicate that the name has not yet been selected, although

9222-450: The relation between expressions and their denotation. One of its key tasks is to provide frameworks of how language represents the world, for example, using ontological models to show how linguistic expressions map to the entities of that model. A common idea is that words refer to individual objects or groups of objects while sentences relate to events and states. Sentences are mapped to a truth value based on whether their description of

9328-489: The relation between language and meaning. Cognitive semantics examines meaning from a psychological perspective and assumes a close relation between language ability and the conceptual structures used to understand the world. Other branches of semantics include conceptual semantics , computational semantics , and cultural semantics. Theories of meaning are general explanations of the nature of meaning and how expressions are endowed with it. According to referential theories ,

9434-403: The role of object language and metalanguage at the same time. This is the case in monolingual English dictionaries , in which both the entry term belonging to the object language and the definition text belonging to the metalanguage are taken from the English language. Lexical semantics is the sub-field of semantics that studies word meaning. It examines semantic aspects of individual words and

9540-402: The same entity. For instance, the expressions Roger Bannister and the first man to run a four-minute mile refer to the same person but do not mean exactly the same thing. This is particularly relevant when talking about beliefs since a person may understand both expressions without knowing that they point to the same entity. A further problem is given by expressions whose meaning depends on

9646-835: The same lines, the Swiss Federal Railways' Transit Police—the Transportpolizei —are abbreviated as the TraPo . With the National Socialist German Workers' Party gaining power came a frenzy of government reorganisation, and with it a series of entirely new syllabic abbreviations. The single national police force amalgamated from the Schutzpolizeien of the various states became the OrPo ( Ordnungspolizei , "order police");

9752-412: The same proposition, like the English sentence "the tree is green" and the German sentence "der Baum ist grün" . Utterance meaning is studied by pragmatics and is about the meaning of an expression on a particular occasion. Sentence meaning and utterance meaning come apart in cases where expressions are used in a non-literal way, as is often the case with irony . Semantics is primarily interested in

9858-427: The same spelling are homonyms , like a bank of a river in contrast to a bank as a financial institution. Hyponymy is closely related to meronymy , which describes the relation between part and whole. For instance, wheel is a meronym of car . An expression is ambiguous if it has more than one possible meaning. In some cases, it is possible to disambiguate them to discern the intended meaning. The term polysemy

9964-440: The scope of semantics while others consider them part of the distinct discipline of pragmatics. Theories of meaning explain what meaning is, what meaning an expression has, and how the relation between expression and meaning is established. Referential theories state that the meaning of an expression is the entity to which it points. The meaning of singular terms like names is the individual to which they refer. For example,

10070-401: The secret police) and VoPo for Volkspolizei . The phrase politisches Büro , which may be rendered literally as "office of politics" or idiomatically as "political party steering committee", became Politbüro . Syllabic abbreviations are not only used in politics, however. Many business names, trademarks, and service marks from across Germany are created on the same pattern: for

10176-410: The sentence "it is raining outside" that raindrops are falling from the sky. The sentence is true if it is used in a situation in which the truth conditions are fulfilled, i.e., if there is actually rain outside. Truth conditions play a central role in semantics and some theories rely exclusively on truth conditions to analyze meaning. To understand a statement usually implies that one has an idea about

10282-556: The state KriPos together formed the "SiPo" ( Sicherheitspolizei , "security police"); and there was also the Gestapo ( Geheime Staatspolizei , "secret state police"). The new order of the German Democratic Republic in the east brought about a conscious denazification , but also a repudiation of earlier turns of phrase in favour of neologisms such as Stasi for Staatssicherheit ("state security",

10388-546: The style guides of The Chicago Manual of Style and the Associated Press . The U.S. government follows a style guide published by the U.S. Government Printing Office . The National Institute of Standards and Technology sets the style for abbreviations of units. Many British publications follow some of these guidelines in abbreviation: Writers often use shorthand to denote units of measure. Such shorthand can be an abbreviation, such as "in" for " inch " or can be

10494-971: The term abbreviation in loose parlance. In early times, abbreviations may have been common due to the effort involved in writing (many inscriptions were carved in stone) or to provide secrecy via obfuscation . Reduction of a word to a single letter was common in both Greek and Roman writing. In Roman inscriptions, "Words were commonly abbreviated by using the initial letter or letters of words, and most inscriptions have at least one abbreviation". However, "some could have more than one meaning, depending on their context. (For example, ⟨A⟩ can be an abbreviation for many words, such as ager , amicus , annus , as , Aulus , Aurelius , aurum , and avus .)" Many frequent abbreviations consisted of more than one letter: for example COS for consul and COSS for its nominative etc. plural consules . Abbreviations were frequently used in early English . Manuscripts of copies of

10600-516: The vocabulary as generic words are no longer written with capital letters nor with any periods. Examples are sonar , radar , lidar , laser , snafu , and scuba . When an abbreviation appears at the end of a sentence, only one period is used: The capital of the United States is Washington, D.C. In the past, some initialisms were styled with a period after each letter and a space between each pair. For example, U. S. , but today this

10706-407: The word dog is associated with the concept of the four-legged domestic animal. Sentence meaning falls into the field of phrasal semantics and concerns the denotation of full sentences. It usually expresses a concept applying to a type of situation, as in the sentence "the dog has ruined my blue skirt". The meaning of a sentence is often referred to as a proposition . Different sentences can express

10812-464: The words in a typical SMS message are abbreviated. More recently Twitter, a popular social networking service , began driving abbreviation use with 140 character message limits. In HTML , abbreviations can be annotated using < abbr title = "Meaning of the abbreviation." > abbreviation </ abbr > to reveal its meaning by hovering the cursor . In modern English, there are multiple conventions for abbreviation, and there

10918-432: The world and see them instead as interrelated phenomena. They study how the interaction between language and human cognition affects the conceptual organization in very general domains like space, time, causation, and action. The contrast between profile and base is sometimes used to articulate the underlying knowledge structure. The profile of a linguistic expression is the aspect of the knowledge structure that it brings to

11024-542: The world is in correspondence with its ontological model. Formal semantics further examines how to use formal mechanisms to represent linguistic phenomena such as quantification , intensionality , noun phrases , plurals , mass terms, tense , and modality . Montague semantics is an early and influential theory in formal semantics that provides a detailed analysis of how the English language can be represented using mathematical logic. It relies on higher-order logic , lambda calculus , and type theory to show how meaning

And wherɔ y wrot to you the last wyke that y trouyde itt good to differrɔ thelectionɔ ovɔ to quīdenaɔ tinitatis y have be thougħt me synɔ that itt woll be thenɔ a bowte mydsomɔ. In the Early Modern English period, between the 15th and 17th centuries, the thorn Þ

11236-451: Was used for th , as in Þ ('the'). In modern times, ⟨Þ⟩ was often used (in the form ⟨y⟩ ) for promotional reasons, as in Y Olde Tea Shoppe . During the growth of philological linguistic theory in academic Britain, abbreviating became very fashionable. Likewise, a century earlier in Boston , a fad of abbreviation started that swept the United States, with
