68-582: The Kxʼa ( / ˈ k ɑː / KAH ) languages, also called Ju–ǂHoan ( / ˌ dʒ uː ˈ h oʊ æ n / joo- HOH -an ), is a language family established in 2010 linking the ǂʼAmkoe (ǂHoan) language with the ǃKung (Juu) dialect cluster, a relationship that had been suspected for a decade. Along with the Tuu languages and Khoe languages , they are one of three language families indigenous to southern Africa, which are typologically similar due to areal effects. ǂʼAmkoe had previously been lumped in with
136-474: A Japonic language family rather than dialects of Japanese, the Japanese language itself was considered a language isolate and therefore the only language in its family. Most of the world's languages are known to be related to others. Those that have no known relatives (or for which family relationships are only tentatively proposed) are called language isolates , essentially language families consisting of
204-546: A French Jesuit who spent most of his life in India, had specifically demonstrated the analogy between Sanskrit and European languages. According to current academic consensus, Jones's famous work of 1786 was less accurate than his predecessors', as he erroneously included Egyptian , Japanese and Chinese in the Indo-European languages, while omitting Hindi . In 1818, Danish linguist Rasmus Christian Rask elaborated
272-677: A PIE homeland, the Kurgan and Anatolian hypotheses are the ones most widely accepted, and also the ones most debated against each other. Following the publication of several studies on ancient DNA in 2015, Colin Renfrew, the original author and proponent of the Anatolian hypothesis, has accepted the reality of migrations of populations speaking one or several Indo-European languages from the Pontic steppe towards Northwestern Europe. The table lists
340-549: A conventional mark of reconstructed words, such as * wódr̥ , * ḱwn̥tós , or * tréyes ; these forms are the reconstructed ancestors of the modern English words water , hound , and three , respectively. No direct evidence of PIE exists; scholars have reconstructed PIE from its present-day descendants using the comparative method . For example, compare the pairs of words in Italian and English: piede and foot , padre and father , pesce and fish . Since there
408-453: A detailed, though conservative, overview of the lexical knowledge accumulated by 1959. Jerzy Kuryłowicz's 1956 Apophonie gave a better understanding of Indo-European ablaut . From the 1960s, knowledge of Anatolian became robust enough to establish its relationship to PIE. Scholars have proposed multiple hypotheses about when, where, and by whom PIE was spoken. The Kurgan hypothesis , first put forward in 1956 by Marija Gimbutas , has become
476-627: A language. From the 1870s, the Neogrammarians proposed that sound laws have no exceptions, as illustrated by Verner's law , published in 1876, which resolved apparent exceptions to Grimm's law by exploring the role of accent (stress) in language change. August Schleicher 's A Compendium of the Comparative Grammar of the Indo-European, Sanskrit, Greek and Latin Languages (1874–77) represented an early attempt to reconstruct
544-509: A linguistic area). In a similar vein, there are many similar unique innovations in Germanic , Baltic and Slavic that are far more likely to be areal features than traceable to a common proto-language. But legitimate uncertainty about whether shared innovations are areal features, coincidence, or inheritance from a common ancestor, leads to disagreement over the proper subdivisions of any large language family. The concept of language families
612-426: A number of sign languages have developed in isolation and appear to have no relatives at all. Nonetheless, such cases are relatively rare and most well-attested languages can be unambiguously classified as belonging to one language family or another, even if this family's relation to other families is not known. Language contact can lead to the development of new languages from the mixture of two or more languages for
680-537: A proto-language into daughter languages typically occurs through geographical separation, with different regional dialects of the proto-language undergoing different language changes and thus becoming distinct languages over time. One well-known example of a language family is the Romance languages , including Spanish , French , Italian , Portuguese , Romanian , Catalan , and many others, all of which are descended from Vulgar Latin . The Romance family itself
748-495: A secondary development in ǂʼAmkoe. He cites the ǂʼAmkoe words for 'one' and 'two', /ŋ͡ʘũ/ and /ʘoa/ , where no other Khoisan language has a labial consonant of any kind in its words for these numerals. Sands (2014) notes that ǂʼAmkoe bilabial clicks correspond to all clicks places in ǃKung except for palatal. She postulates that these reflect labialized clicks in Proto-Kxʼa: *ǀʷ *ǃʷ *‼ʷ *ǁʷ . These became bilabial in ǂʼAmkoe, while

#1732772117726816-427: A single language and have no single ancestor. Isolates are languages that cannot be proven to be genealogically related to any other modern language. As a corollary, every language isolate also forms its own language family — a genetic family which happens to consist of just one language. One often cited example is Basque , which forms a language family on its own; but there are many other examples outside Europe. On
884-512: A single language. A speech variety may also be considered either a language or a dialect depending on social or political considerations. Thus, different sources, especially over time, can give wildly different numbers of languages within a certain family. Classifications of the Japonic family , for example, range from one language (a language isolate with dialects) to nearly twenty—until the classification of Ryukyuan as separate languages within
952-462: A single language. There are an estimated 129 language isolates known today. An example is Basque . In general, it is assumed that language isolates have relatives or had relatives at some point in their history but at a time depth too great for linguistic comparison to recover them. A language isolate is classified based on the fact that enough is known about the isolate to compare it genetically to other languages but no common ancestry or relationship
1020-613: A thousand years. According to the prevailing Kurgan hypothesis , the original homeland of the Proto-Indo-Europeans may have been in the Pontic–Caspian steppe of eastern Europe. The linguistic reconstruction of PIE has provided insight into the pastoral culture and patriarchal religion of its speakers. As speakers of Proto-Indo-European became isolated from each other through the Indo-European migrations ,
1088-422: Is a consistent correspondence of the initial consonants ( p and f ) that emerges far too frequently to be coincidental, one can infer that these languages stem from a common parent language . Detailed analysis suggests a system of sound laws to describe the phonetic and phonological changes from the hypothetical ancestral words to the modern ones. These laws have become so detailed and reliable as to support
1156-487: Is a geographic area having several languages that feature common linguistic structures. The similarities between those languages are caused by language contact, not by chance or common origin, and are not recognized as criteria that define a language family. An example of a sprachbund would be the Indian subcontinent . Shared innovations, acquired by borrowing or other means, are not considered genetic and have no bearing with
1224-450: Is a group of languages related through descent from a common ancestor, called the proto-language of that family. The term family is a metaphor borrowed from biology, with the tree model used in historical linguistics analogous to a family tree , or to phylogenetic trees of taxa used in evolutionary taxonomy . Linguists thus describe the daughter languages within a language family as being genetically related . The divergence of
1292-483: Is also a sister language to that fourth branch, then the two sister languages are more closely related to each other than to that common ancestral proto-language. The term macrofamily or superfamily is sometimes applied to proposed groupings of language families whose status as phylogenetic units is generally considered to be unsubstantiated by accepted historical linguistic methods. Some close-knit language families, and many branches within larger families, take
1360-452: Is an absolute isolate: it has not been shown to be related to any other modern language despite numerous attempts. A language may be said to be an isolate currently but not historically if related but now extinct relatives are attested. The Aquitanian language , spoken in Roman times, may have been an ancestor of Basque, but it could also have been a sister language to the ancestor of Basque. In
1428-543: Is based on the historical observation that languages develop dialects , which over time may diverge into distinct languages. However, linguistic ancestry is less clear-cut than familiar biological ancestry, in which species do not crossbreed. It is more like the evolution of microbes, with extensive lateral gene transfer . Quite distantly related languages may affect each other through language contact , which in extreme cases may lead to languages with no single ancestor, whether they be creoles or mixed languages . In addition,

PIE nominals and pronouns had a complex system of declension , and verbs similarly had a complex system of conjugation . The PIE phonology , particles , numerals , and copula are also well-reconstructed. Asterisks are used by linguists as
1564-470: Is found with any other known language. A language isolated in its own branch within a family, such as Albanian and Armenian within Indo-European, is often also called an isolate, but the meaning of the word "isolate" in such cases is usually clarified with a modifier . For instance, Albanian and Armenian may be referred to as an "Indo-European isolate". By contrast, so far as is known, the Basque language
1632-460: Is no upper bound to the number of languages a family can contain. Some families, such as the Austronesian languages , contain over 1000. Language families can be identified from shared characteristics amongst languages. Sound changes are one of the strongest pieces of evidence that can be used to identify a genetic relationship because of their predictable and consistent nature, and through

Linguistic interference can occur between languages that are genetically closely related, between languages that are distantly related (like English and French, which are distantly related Indo-European languages ) and between languages that have no genetic relationship. Some exceptions to the simple genetic relationship model of languages include language isolates and mixed , pidgin and creole languages . Mixed languages, pidgins and creole languages constitute special genetic types of languages. They do not descend linearly or directly from
1768-451: Is not attested by written records and so is conjectured to have been spoken before the invention of writing. A common visual representation of a language family is given by a genetic language tree. The tree model is sometimes termed a dendrogram or phylogeny . The family tree shows the relationship of the languages within a family, much as a family tree of an individual shows their relationship with their relatives. There are criticisms to
1836-446: Is part of the larger Indo-European family, which includes many other languages native to Europe and South Asia , all believed to have descended from a common ancestor known as Proto-Indo-European . A language family is usually said to contain at least two languages, although language isolates — languages that are not related to any other language — are occasionally referred to as families that contain one language. Inversely, there
1904-422: Is possible to recover many features of a proto-language by applying the comparative method , a reconstructive procedure worked out by 19th century linguist August Schleicher . This can demonstrate the validity of many of the proposed families in the list of language families . For example, the reconstructible common ancestor of the Indo-European language family is called Proto-Indo-European . Proto-Indo-European
1972-472: Is shared by the two branches of the family, though also by neighboring languages such as Kwadi . Honken & Heine (2010) reconstruct six places of click articulation for Proto-Kxʼa: the five coronal places that occur in Central ǃKung, plus the bilabial clicks of ǂʼAmkoe. They postulate that the ancestral bilabial clicks became dental in ǃKung. However, Starostin (2003) argues that the bilabial clicks are
2040-424: Is the reconstructed common ancestor of the Indo-European language family . No direct record of Proto-Indo-European exists; its proposed features have been derived by linguistic reconstruction from documented Indo-European languages. Far more work has gone into reconstructing PIE than any other proto-language , and it is the best understood of all proto-languages of its age. The majority of linguistic work during
2108-506: The Indian subcontinent became aware of similarities between Indo-Iranian languages and European languages, and as early as 1653, Marcus Zuerius van Boxhorn had published a proposal for a proto-language ("Scythian") for the following language families: Germanic , Romance , Greek , Baltic , Slavic , Celtic , and Iranian . In a memoir sent to the Académie des Inscriptions et Belles-Lettres in 1767, Gaston-Laurent Coeurdoux ,

2176-591: The Neogrammarian hypothesis : the Indo-European sound laws apply without exception. William Jones , an Anglo-Welsh philologist and puisne judge in Bengal , caused an academic sensation when in 1786 he postulated the common ancestry of Sanskrit , Greek , Latin , Gothic , the Celtic languages , and Old Persian , but he was not the first to state such a hypothesis. In the 16th century, European visitors to
2244-465: The North Germanic language family, including Danish , Swedish , Norwegian and Icelandic , which have shared descent from Ancient Norse . Latin and ancient Norse are both attested in written records, as are many intermediate stages between those ancestral languages and their modern descendants. In other cases, genetic relationships between languages are not directly attested. For instance,
2312-674: The comparative method can be used to reconstruct proto-languages. However, languages can also change through language contact which can falsely suggest genetic relationships. For example, the Mongolic , Tungusic , and Turkic languages share a great deal of similarities that lead several scholars to believe they were related . These supposed relationships were later discovered to be derived through language contact and thus they are not truly related. Eventually though, high amounts of language contact and inconsistent changes will render it essentially impossible to derive any more relationships; even
2380-489: The comparative method of linguistic analysis. In order to test the hypothesis that two languages are related, the comparative method begins with the collection of pairs of words that are hypothesized to be cognates : i.e., words in related languages that are derived from the same word in the shared ancestral language. Pairs of words that have similar pronunciations and meanings in the two languages are often good candidates for hypothetical cognates. The researcher must rule out
2448-478: The 19th century was devoted to the reconstruction of PIE and its daughter languages , and many of the modern techniques of linguistic reconstruction (such as the comparative method ) were developed as a result. PIE is hypothesized to have been spoken as a single language from approximately 4500 BCE to 2500 BCE during the Late Neolithic to Early Bronze Age , though estimates vary by more than
2516-569: The North Adriatic region are sometimes classified as Italic. Albanian and Greek are the only surviving Indo-European descendants of a Paleo-Balkan language area, named for their occurrence in or in the vicinity of the Balkan peninsula . Most of the other languages of this area—including Illyrian , Thracian , and Dacian —do not appear to be members of any other subfamilies of PIE, but are so poorly attested that proper classification of them

Other theories include the Anatolian hypothesis , which posits that PIE spread out from Anatolia with agriculture beginning c. 7500–6000 BCE, the Armenian hypothesis , the Paleolithic continuity paradigm , and the indigenous Aryans theory. The last two of these theories are not regarded as credible within academia. Out of all the theories for

The Lusitanian language was a marginally attested language spoken in areas near the border between present-day Portugal and Spain . The Venetic and Liburnian languages known from
2720-568: The Romance languages and the North Germanic languages are also related to each other, being subfamilies of the Indo-European language family , since both Latin and Old Norse are believed to be descended from an even more ancient language, Proto-Indo-European ; however, no direct evidence of Proto-Indo-European or its divergence into its descendant languages survives. In cases such as these, genetic relationships are established through use of
2788-505: The Tuu languages, perhaps over confusion with the dialect name ǂHȍȁn, but the only thing they have in common are typological features such as their bilabial clicks . Honken & Heine (2010) coined the term Kxʼa for the family as a replacement for the rather inaccessible compound Ju–ǂHoan (easily confused with the Juǀʼhoan language), after the word [kxʼà] 'earth, ground', which

2856-496: The common ancestor of the Germanic subfamily, was itself a descendant of Proto-Indo-European , the common ancestor of the Indo-European family. Within a large family, subfamilies can be identified through "shared innovations": members of a subfamily will share features that represent retentions from their more recent common ancestor, but were not present in the overall proto-language of the larger family. Some taxonomists restrict
2924-546: The common origin of Sanskrit, Persian, Greek, Latin, and German. In 1833, he began publishing the Comparative Grammar of Sanskrit, Zend , Greek, Latin, Lithuanian, Old Slavic, Gothic, and German . In 1822, Jacob Grimm formulated what became known as Grimm's law as a general rule in his Deutsche Grammatik . Grimm showed correlations between the Germanic and other Indo-European languages and demonstrated that sound change systematically transforms all words of
2992-582: The effects of hypothetical sounds which no longer exist in all languages documented prior to the excavation of cuneiform tablets in Anatolian. This theory was first proposed by Ferdinand de Saussure in 1879 on the basis of internal reconstruction only, and progressively won general acceptance after Jerzy Kuryłowicz 's discovery of consonantal reflexes of these reconstructed sounds in Hittite. Julius Pokorny 's Indogermanisches etymologisches Wörterbuch ('Indo-European Etymological Dictionary', 1959) gave
3060-563: The family tree model. Critics focus mainly on the claim that the internal structure of the trees is subject to variation based on the criteria of classification. Even among those who support the family tree model, there are debates over which languages should be included in a language family. For example, within the dubious Altaic language family , there are debates over whether the Japonic and Koreanic languages should be included or not. The wave model has been proposed as an alternative to
3128-415: The family. The largest five language families in terms of number of speakers (Indo-European, Sino-Tibetan, Afro-Asiatic, Niger-Congo and Austronesian) make up five-sixths (almost 83.3%) of the world’s population. Two languages have a genetic relationship , and belong to the same language family, if both are descended from a common ancestor through the process of language change , or one is descended from
3196-415: The family. Thus, the term family is analogous to the biological term clade . Language families can be divided into smaller phylogenetic units, sometimes referred to as "branches" or "subfamilies" of the family; for instance, the Germanic languages are a subfamily of the Indo-European family. Subfamilies share a more recent common ancestor than the common ancestor of the larger family; Proto-Germanic ,
3264-495: The following families that contain at least 1% of the 7,164 known languages in the world: Glottolog 5.0 (2024) lists the following as the largest families, of 7,788 languages (other than sign languages , pidgins , and unclassifiable languages ): Language counts can vary significantly depending on what is considered a dialect; for example Lyle Campbell counts only 27 Otomanguean languages, although he, Ethnologue and Glottolog also disagree as to which languages belong in
3332-468: The form of dialect continua in which there are no clear-cut borders that make it possible to unequivocally identify, define, or count individual languages within the family. However, when the differences between the speech of different regions at the extremes of the continuum are so great that there is no mutual intelligibility between them, as occurs in Arabic , the continuum cannot meaningfully be seen as
3400-503: The global scale, the site Glottolog counts a total of 423 language families in the world, including 184 isolates. One controversial theory concerning the genetic relationships among languages is monogenesis , the idea that all known languages, with the exceptions of creoles , pidgins and sign languages , are descendant from a single ancestral language. If that is true, it would mean all languages (other than pidgins, creoles, and sign languages) are genetically related, but in many cases,
3468-542: The language family concept. It has been asserted, for example, that many of the more striking features shared by Italic languages ( Latin , Oscan , Umbrian , etc.) might well be " areal features ". However, very similar-looking alterations in the systems of long vowels in the West Germanic languages greatly postdate any possible notion of a proto-language innovation (and cannot readily be regarded as "areal", either, since English and continental West Germanic were not

#17327721177263536-444: The latter case, Basque and Aquitanian would form a small family together. Ancestors are not considered to be distinct members of a family. A proto-language can be thought of as a mother language (not to be confused with a mother tongue ) being the root from which all languages in the family stem. The common ancestor of a language family is seldom known directly since most languages have a relatively short recorded history. However, it

Slavic: Russian , Ukrainian , Belarusian , Polish , Czech , Slovak , Sorbian , Serbo-Croatian , Bulgarian , Slovenian , Macedonian , Kashubian , Rusyn Iranic: Persian , Pashto , Balochi , Kurdish , Zaza , Ossetian , Luri , Talyshi , Tati , Gilaki , Mazandarani , Semnani , Yaghnobi ; Nuristani Commonly proposed subgroups of Indo-European languages include Italo-Celtic , Graeco-Aryan , Graeco-Armenian , Graeco-Phrygian , Daco-Thracian , and Thraco-Illyrian . There are numerous lexical similarities between
3672-534: The most popular. It proposes that the original speakers of PIE were the Yamnaya culture associated with the kurgans (burial mounds) on the Pontic–Caspian steppe north of the Black Sea. According to the theory, they were nomadic pastoralists who domesticated the horse , which allowed them to migrate across Europe and Asia in wagons and chariots. By the early 3rd millennium BCE, they had expanded throughout
3740-423: The oldest demonstrable language family, Afroasiatic , is far younger than language itself. Estimates of the number of language families in the world may vary widely. According to Ethnologue there are 7,151 living human languages distributed in 142 different language families. Lyle Campbell (2019) identifies a total of 406 independent language families, including isolates. Ethnologue 27 (2024) lists
3808-594: The only traces of the labialization in ǃKung are diphthongs. An example, from Proto-Kxʼa *‼ʷ, is 'tail' in ǂHoan /ʘχúì/ , Juǀʼhoan /ǃxúi/ and Ekoka /ǁxóe/ (from Proto-Ju *‼xoe: retroflex clicks merged with alveolars in Southern ǃKung, with laterals in Northern ǃKung, and only remained retroflex in Central ǃKung.) The lack of **ǂʷ is not surprising, given the relative rarity of labiovelarized palatals crosslinguistically. Language family A language family

3944-454: The other. The term and the process of language evolution are independent of, and not reliant on, the terminology, understanding, and theories related to genetics in the biological sense, so, to avoid confusion, some linguists prefer the term genealogical relationship . There is a remarkably similar pattern shown by the linguistic tree and the genetic tree of human ancestry that was verified statistically. Languages interpreted in terms of
4012-470: The possibility that the two words are similar merely due to chance, or due to one having borrowed the words from the other (or from a language related to the other). Chance resemblance is ruled out by the existence of large collections of pairs of words between the two languages showing similar patterns of phonetic similarity. Once coincidental similarity and borrowing have been eliminated as possible explanations for similarities in sound and meaning of words,
4080-426: The proto-Indo-European language. By the early 1900s, Indo-Europeanists had developed well-defined descriptions of PIE which scholars still accept today. Later, the discovery of the Anatolian and Tocharian languages added to the corpus of descendant languages. A subtle new principle won wide acceptance: the laryngeal theory , which explained irregularities in the reconstruction of Proto-Indo-European phonology as
4148-653: The purposes of interactions between two groups who speak different languages. Languages that arise in order for two groups to communicate with each other to engage in commercial trade or that appeared as a result of colonialism are called pidgin . Pidgins are an example of linguistic and cultural expansion caused by language contact. However, language contact can also lead to cultural divisions. In some cases, two different language speaking groups can feel territorial towards their language and do not want any changes to be made to it. This causes language boundaries and groups in contact are not willing to make any compromises to accommodate
SECTION 60
#17327721177264216-536: The putative phylogenetic tree of human languages are transmitted to a great extent vertically (by ancestry) as opposed to horizontally (by spatial diffusion). In some cases, the shared derivation of a group of related languages from a common ancestor is directly attested in the historical record. For example, this is the case for the Romance language family , wherein Spanish , Italian , Portuguese , Romanian , and French are all descended from Latin, as well as for
4284-428: The regional dialects of Proto-Indo-European spoken by the various groups diverged, as each dialect underwent shifts in pronunciation (the Indo-European sound laws ), morphology, and vocabulary. Over many centuries, these dialects transformed into the known ancient Indo-European languages. From there, further linguistic divergence led to the evolution of their current descendants, the modern Indo-European languages. PIE
4352-413: The relationships may be too remote to be detectable. Alternative explanations for some basic observed commonalities between languages include developmental theories, related to the biological development of the capacity for language as the child grows from newborn. A language family is a monophyletic unit; all its members derive from a common ancestor, and all descendants of that ancestor are included in
4420-570: The remaining explanation is common origin: it is inferred that the similarities occurred due to descent from a common ancestor, and the words are actually cognates, implying the languages must be related. When languages are in contact with one another , either of them may influence the other through linguistic interference such as borrowing. For example, French has influenced English , Arabic has influenced Persian , Sanskrit has influenced Tamil , and Chinese has influenced Japanese in this way. However, such influence does not constitute (and
4488-730: The set of correspondences in his prize essay Undersøgelse om det gamle Nordiske eller Islandske Sprogs Oprindelse ('Investigation of the Origin of the Old Norse or Icelandic Language'), where he argued that Old Norse was related to the Germanic languages, and had even suggested a relation to the Baltic, Slavic, Greek, Latin and Romance languages. In 1816, Franz Bopp published On the System of Conjugation in Sanskrit , in which he investigated
4556-426: The term family to a certain level, but there is little consensus on how to do so. Those who affix such labels also subdivide branches into groups , and groups into complexes . A top-level (i.e., the largest) family is often called a phylum or stock . The closer the branches are to each other, the more closely the languages will be related. This means if a branch of a proto-language is four branches down and there
4624-502: The tree model. The wave model uses isoglosses to group language varieties; unlike in the tree model, these groups can overlap. While the tree model implies a lack of contact between languages after derivation from an ancestral form, the wave model emphasizes the relationship between languages that remain in contact, which is more realistic. Historical glottometry is an application of the wave model, meant to identify and evaluate genetic relations in linguistic linkages . A sprachbund
