(Redirected from Genetic relatedness of languages)
A 'language family' is a group of languages related by descent from a common proto-language. As with human biological families, the evidence of relationship is observable shared characteristics. An accurately identified family is a phylogenetic unit; that is, all its members derive from a common ancestor. Many languages are known to belong to language families; for many others, however, family relationships are not known and only tentatively proposed.
The concept of language families is based on the concept of historical ancestors for languages—normally the gradual evolution over time of one language into other languages, rather than the sudden creation of new languages. The concept of linguistic ancestry is less clear-cut than the concept of biological ancestry, because there are cases of extreme historical language contact, due to conquest or trade. In the formation of creole languages and other types of mixed languages, it may be unclear which language should be considered the ancestor of a given language. However, these types of cases are relatively rare and most languages can be unambiguously classified into families.
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 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 is not attested by written records, since it was spoken before the invention of writing.
Sometimes, though, a proto-language ''can'' be identified with an historically known language. Provincial dialects of Latin ("Vulgar Latin") gave rise to the modern Romance languages, so the Proto-Romance language is more or less identical with Latin (if not exactly with the literary Latin of the Classical writers). Similarly, dialects of Old Norse are the proto-language of Norwegian, Swedish, Danish, Faroese and Icelandic.
Language families can be divided into smaller phylogenetic units, conventionally referred to as ''branches'' of the family, because the history of a language family is often represented as a tree diagram. However, the term ''family'' is not restricted to any one level of this "tree". The Germanic family, for example, is a branch of the Indo-European family. Some taxonomists restrict the term ''family'' to a certain level, but there is little consensus in how to do so. Those who affix such labels also subdivide branches into ''groups'', and groups into ''complexes''. The terms ''superfamily'', ''phylum'', and ''stock'' are applied to proposed groupings of language families whose status as phylogenetic units is generally considered to be unsubstantiated by accepted historical linguistic methods.
Languages that cannot be reliably classified into any family are known as ''isolates''. A language isolated in its own branch within a family, such as Greek within Indo-European, is often also called an isolate; but the meaning of ''isolate'' in such cases is usually clarified. For instance, Greek might be referred to as an Indo-European isolate. The isolation of modern Greek, however, is not typical of its relationship to other languages at other times in its history. Several Greek dialects evolved out of the larger Indo-European language group; and later, Greek words influenced many other languages. By contrast, the Basque language is a living modern language and a near perfect isolate. The history of its lexical, phonetic, and syntactic structures is not known, and is not easily associated to other languages, though it has been influenced by Romance languages in the region, like Castilian Spanish, Occitan, and French).
Connections among and between language families are often used by anthropologists, in combination with DNA evidence and fossil evidence, to help reconstruct pre-historic migrations of peoples, and other pre-historic events, such as the spread of agriculture.
The Linguist List is now working on a National Science Foundation funded project entitled ''Multitree'', to build a database of all hypothesized language relationships, with a full searchable bibliography for each.
