In linguistics, the comparative method is a technique for studying the development of languages by performing a feature-by-feature comparison of two or more languages with common descent from a shared ancestor and then extrapolating backwards to infer the properties of that ancestor. The comparative method may be contrasted with the method of internal reconstruction in which the internal development of a single language is inferred by the analysis of features within that language. Ordinarily, both methods are used together to reconstruct prehistoric phases of languages; to fill in gaps in the historical record of a language; to discover the development of phonological, morphological and other linguistic systems and to confirm or to refute hypothesised relationships between languages.
The Indo-European languages are a language family native to the overwhelming majority of Europe, the Iranian plateau, and the northern Indian subcontinent. Some European languages of this family, English, French, Portuguese, Russian, Dutch, and Spanish, have expanded through colonialism in the modern period and are now spoken across several continents. The Indo-European family is divided into several branches or sub-families, of which there are eight groups with languages still alive today: Albanian, Armenian, Balto-Slavic, Celtic, Germanic, Hellenic, Indo-Iranian, and Italic; and another nine subdivisions that are now extinct.
Niger-Congo is a hypothetical language family spoken over the majority of sub-Saharan Africa. It unites the Mande languages, the Atlantic-Congo languages, and possibly several smaller groups of languages that are difficult to classify. If valid, Niger-Congo would be the world's largest in terms of member languages, the third-largest in terms of speakers, and Africa's largest in terms of geographical area. It is generally considered to be the world's largest language family in terms of the number of distinct languages, just ahead of Austronesian, although this is complicated by the ambiguity about what constitutes a distinct language; the number of named Niger–Congo languages listed by Ethnologue is 1,540.
Historical linguistics, also termed diachronic linguistics, is the scientific study of language change over time. Principal concerns of historical linguistics include:
- to describe and account for observed changes in particular languages
- to reconstruct the pre-history of languages and to determine their relatedness, grouping them into language families
- to develop general theories about how and why language changes
- to describe the history of speech communities
- to study the history of words, i.e. etymology
The Mayan languages form a language family spoken in Mesoamerica, both in the south of Mexico and northern Central America. Mayan languages are spoken by at least 6 million Maya people, primarily in Guatemala, Mexico, Belize, El Salvador and Honduras. In 1996, Guatemala formally recognized 21 Mayan languages by name, and Mexico recognizes eight within its territory.
Phoenician is an extinct Canaanite Semitic language originally spoken in the region surrounding the cities of Tyre and Sidon. Extensive Tyro-Sidonian trade and commercial dominance led to Phoenician becoming a lingua franca of the maritime Mediterranean during the Iron Age. The Phoenician alphabet spread to Greece during this period, where it became the source of all modern European scripts.
Proto-Indo-European (PIE) is the reconstructed common ancestor of the Indo-European language family. Its proposed features have been derived by linguistic reconstruction from documented Indo-European languages. No direct record of Proto-Indo-European exists.
Comparative linguistics, or comparative-historical linguistics is a branch of historical linguistics that is concerned with comparing languages to establish their historical relatedness.
Bactrian is an extinct Eastern Iranian language formerly spoken in the Central Asian region of Bactria and used as the official language of the Kushan, and the Hephthalite empires.
Barbacoan is a language family spoken in Colombia and Ecuador.
The Continental Celtic languages are the now-extinct group of the Celtic languages that were spoken on the continent of Europe and in central Anatolia, as distinguished from the Insular Celtic languages of the British Isles and Brittany. Continental Celtic is a geographic, rather than linguistic, grouping of the ancient Celtic languages.
The Iranian languages or Iranic languages are a branch of the Indo-Iranian languages in the Indo-European language family that are spoken natively by the Iranian peoples, predominantly in the Iranian Plateau.
The languages of India are divided into various language families, of which the Indo-Aryan and the Dravidian are the most widely spoken. There are also many languages belonging to unrelated language families such as Austroasiatic and Sino-Tibetan, spoken by smaller groups.
Linguistic reconstruction is the practice of establishing the features of an unattested ancestor language of one or more given languages. There are two kinds of reconstruction:
Internal reconstruction is a method of reconstructing an earlier state in a language's history using only language-internal evidence of the language in question.
In the tree model of historical linguistics, a proto-language is a postulated ancestral language from which a number of attested languages are believed to have descended by evolution, forming a language family. Proto-languages are usually unattested, or partially attested at best. They are reconstructed by way of the comparative method.
Greenlandic Norse is an extinct North Germanic language that was spoken in the Norse settlements of Greenland until their demise in the late 15th century. The language is primarily attested by runic inscriptions found in Greenland. The limited inscriptional evidence shows some innovations, including the use of initial t for þ, but also the conservation of certain features that changed in other Norse languages. Some runic features are regarded as characteristically Greenlandic, and when they are sporadically found outside of Greenland, they may suggest travelling Greenlanders.
Ongan, also called Angan, South Andamanese or Jarawa–Onge, is a phylum of two Andamanese languages, Önge and Jarawa, spoken in the southern Andaman Islands.
The Nambikwaran languages are a language family of half a dozen languages, all spoken in the state of Mato Grosso in Brazil. They have traditionally been considered dialects of a single language, but at least three of them are mutually unintelligible.
Proto-Arabic is the name given to the hypothetical reconstructed ancestor of all the varieties of Arabic attested since the 9th century BC. There are two lines of evidence to reconstruct Proto-Arabic:
