Alanguage familyis a group oflanguagesrelated through descent from a common ancestor, called theproto-languageof that family. The termfamilyis a metaphor borrowed from biology, with thetree modelused inhistorical linguisticsanalogous to afamily tree,or tophylogenetic treesof taxa used in evolutionarytaxonomy.Linguists thus describe thedaughter languageswithin a language family as beinggenetically related.[1]The divergence of a proto-language into daughter languages typically occurs through geographical separation, with differentregional dialectsof the proto-language undergoing differentlanguage changesand thus becoming distinct languages over time.[2]
One well-known example of a language family is theRomance languages,includingCatalan,Spanish,French,Italian,Portuguese,Romanian,and many others, all of which are descended fromVulgar Latin.[note 1][3]The Romance family itself is part of the largerIndo-Europeanfamily, which includes many other languages native to Europe and South Asia, all believed to have descended from a common ancestor known asProto-Indo-European.
A language family is usually said to contain at least two languages, althoughlanguage isolates— languages that are not related to any other language — are occasionally referred to as families that contain one language. Inversely, there is no upper bound to the number of languages a family can contain. Some families, such as theAustronesian languages,contain over 1000.[4]
Language families can be identified from shared characteristics amongst languages.Sound changesare 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 thecomparative methodcan be used to reconstruct proto-languages. However, languages can also change throughlanguage contactwhich can falsely suggest genetic relationships. For example, theMongolic,Tungusic,andTurkic languagesshare a great deal of similarities that lead several scholars to believethey were related.These supposed relationships were later discovered to be derived through language contact and thus they are not truly related.[5]Eventually though, high amounts of language contact and inconsistent changes will render it essentially impossible to derive any more relationships; even the oldest language family,Afroasiatic,is far younger than language itself.[6]
Major language families
[edit]Estimates of the number of language families in the world may vary widely. According toEthnologuethere are 7,151living human languagesdistributed in 142 different language families.[7][8]Lyle Campbell(2019) identifies a total of 406 independent language families, including isolates.[9]
Ethnologue27 (2024) lists the following families that contain at least 1% of the 7,164 known languages in the world:[10]
- Niger–Congo(1,552 languages)
- Austronesian(1,256 languages)
- Trans–New Guinea(481 languages)
- Sino-Tibetan(458 languages)
- Indo-European(454 languages)
- Australian(384 languages)
- Afroasiatic(382 languages)
- Nilo-Saharan(210 languages)
- Otomanguean(179 languages)
- Austroasiatic(167 languages)
- Kra-Dai(91 languages)
- Dravidian(85 languages)
Glottolog5.0 (2024) lists the following as the largest families, of 7,788 languages (other than sign languages, pidgins, and unclassifiable languages):[11]
- Atlantic–Congo(1,410 languages)
- Austronesian(1,274 languages)
- Indo-European(586 languages)
- Sino-Tibetan(514 languages)
- Afroasiatic(381 languages)
- NuclearTrans–New Guinea(316 languages)
- Pama–Nyungan(250 languages)
- Otomanguean(181 languages)
- Austroasiatic(158 languages)
- Tai–Kadai(95 languages)
- Dravidian(82 languages)
- Arawakan(77 languages)
Language counts can vary significantly depending on what is considered a dialect; for exampleLyle Campbellcounts only 27 Otomanguean languages, although he,EthnologueandGlottologalso disagree as to which languages belong in the family.
Genetic relationship
[edit]Two languages have agenetic relationship,and belong to the same language family, if both are descended from a common ancestor through the process oflanguage change,or one is descended from the other. The term and the process of language evolution are independent of, and not reliant on, the terminology, understanding, and theories related togeneticsin the biological sense, so, to avoid confusion, some linguists prefer the termgenealogical relationship.[12][13]: 184
There is a remarkably similar pattern shown by the linguistic tree and the genetic tree of human ancestry[14] that was verified statistically.[15]Languages interpreted in terms of the putative phylogenetic tree of human languages are transmitted to a great extent vertically (by ancestry) as opposed to horizontally (by spatial diffusion).[16]
Establishment
[edit]In some cases, the shared derivation of a group of related languages from a common ancestor is directlyattestedin the historical record. For example, this is the case for theRomance language family,whereinSpanish,Italian,Portuguese,Romanian,andFrenchare all descended from Latin, as well as for theNorth Germaniclanguage family, includingDanish,Swedish,NorwegianandIcelandic,which have shared descent fromAncient 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, the Romance languages and the North Germanic languages are also related to each other, being subfamilies of theIndo-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 thecomparative methodof 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 becognates: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 the possibility that the two words are similar merely due to chance, or due to one havingborrowedthe 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 andborrowinghave been eliminated as possible explanations for similarities in sound and meaning of words, 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.[17]
Linguistic interference and borrowing
[edit]When languages are incontact with one another,either of them may influence the other throughlinguistic interferencesuch as borrowing. For example,Frenchhas influencedEnglish,Arabichas influencedPersian,Sanskrithas influencedTamil,andChinesehas influencedJapanesein this way. However, such influence does not constitute (and is not a measure of) a genetic relationship between the languages concerned. Linguistic interference can occur between languages that are genetically closely related, between languages that are distantly related (like English and French, which are distantly relatedIndo-European languages) and between languages that have no genetic relationship.
Complications
[edit]Some exceptions to the simple genetic relationship model of languages includelanguage isolatesandmixed,pidginandcreole languages.
Mixed languages, pidgins and creole languages constitute special genetic types of languages. They do not descend linearly or directly from a single language and have no single ancestor.
Isolatesare 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 isBasque,which forms a language family on its own; but there are many other examples outside Europe. On the global scale, the siteGlottologcounts a total of 423 language families in the world, including 184 isolates.[18]
Monogenesis
[edit]One controversial theory concerning the genetic relationships among languages ismonogenesis,the idea that all known languages, with the exceptions ofcreoles,pidgins andsign languages,are descendant from a single ancestral language.[19]If that is true, it would mean all languages (other than pidgins, creoles, and sign languages) are genetically related, but in many cases, 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.[citation needed]
Structure of a family
[edit]This sectionneeds additional citations forverification.(May 2022) |
A language family is amonophyleticunit; all its members derive from a common ancestor, and all descendants of that ancestor are included in the family. Thus, the termfamilyis analogous to the biological termclade.Language families can be divided into smaller phylogenetic units, sometimes referred to as "branches" or "subfamilies" of the family; for instance, theGermanic languagesare a subfamily of theIndo-Europeanfamily. Subfamilies share a more recent common ancestor than the common ancestor of the larger family;Proto-Germanic,the common ancestor of the Germanic subfamily, was itself a descendant ofProto-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.
Sometaxonomistsrestrict the termfamilyto a certain level, but there is little consensus on how to do so. Those who affix such labels also subdivide branches intogroups,and groups intocomplexes.A top-level (i.e., the largest) family is often called aphylumorstock.The closer the branches are to each other, the more closely the languages will be related. This means if a branch of aproto-languageis four branches down and there is also asister languageto that fourth branch, then the two sister languages are more closely related to each other than to that common ancestral proto-language.
The termmacrofamilyorsuperfamilyis sometimes applied to proposed groupings of language families whose status as phylogenetic units is generally considered to be unsubstantiated by acceptedhistorical linguisticmethods.
Dialect continua
[edit]Some close-knit language families, and many branches within larger families, take the form ofdialect continuain 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 nomutual intelligibilitybetween them, as occurs inArabic,the continuum cannot meaningfully be seen as 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 ofRyukyuanas separate languages within aJaponic language familyrather than dialects of Japanese, theJapanese languageitself was considered alanguage isolateand therefore the only language in its family.
Isolates
[edit]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 calledlanguage isolates,essentially language families consisting of a single language. There are an estimated 129 language isolates known today.[20]An example isBasque.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 is found with any other known language.[20]
A language isolated in its own branch within a family, such asAlbanianandArmenianwithin Indo-European, is often also called an isolate, but the meaning of the word "isolate" in such cases is usually clarified with amodifier.For instance, Albanian and Armenian may be referred to as an "Indo-European isolate". By contrast, so far as is known, theBasque languageis 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. TheAquitanian 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 the latter case, Basque and Aquitanian would form a small family together. Ancestors are not considered to be distinct members of a family.[citation needed]
Proto-languages
[edit]A proto-language can be thought of as a mother language (not to be confused with amother tongue[21]) 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 is possible to recover many features of a proto-language by applying thecomparative method,a reconstructive procedure worked out by 19th century linguistAugust Schleicher.This can demonstrate the validity of many of the proposed families in thelist of language families.For example, the reconstructible common ancestor of the Indo-European language family is calledProto-Indo-European.Proto-Indo-European is not attested by written records and so is conjectured to have been spoken before the invention of writing.
Visual representation
[edit]![](https://upload.wikimedia.org/wikipedia/commons/thumb/b/bd/20150714040758%21Mayan_languages_tree_gl.svg/300px-20150714040758%21Mayan_languages_tree_gl.svg.png)
A common visual representation of a language family is given by a genetic language tree. Thetree modelis sometimes termed adendrogramorphylogeny.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 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.[22]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 dubiousAltaic language family,there are debates over whether theJaponicandKoreaniclanguages should be included or not.[23]
Thewave modelhas been proposed as an alternative to the tree model.[13]The wave model usesisoglossesto 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.[13]Historical glottometryis an application of the wave model, meant to identify and evaluate genetic relations inlinguistic linkages.[13][24]
Other classifications of languages
[edit]This sectionneeds additional citations forverification.(May 2022) |
Sprachbund
[edit]Asprachbundis 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 theIndian subcontinent.[25]
Shared innovations, acquired by borrowing or other means, are not considered genetic and have no bearing with the language family concept. It has been asserted, for example, that many of the more striking features shared byItalic languages(Latin,Oscan,Umbrian,etc.) might well be "areal features".However, very similar-looking alterations in the systems of long vowels in theWest Germanic languagesgreatly 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 a linguistic area). In a similar vein, there are many similar unique innovations inGermanic,BalticandSlavicthat 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.
Contact languages
[edit]The concept of language families is based on the historical observation that languages developdialects,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.[26]It is more like the evolution of microbes, with extensivelateral gene transfer.Quite distantly related languages may affect each other throughlanguage contact,which in extreme cases may lead to languages with no single ancestor, whether they becreolesormixed languages.In addition, a number ofsign languageshave 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 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 calledpidgin.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 the other language.[27]
