Language convergence is a type of linguistic change in which languages come to resemble one another structurally as a result of prolonged language contact and mutual interference, regardless of whether those languages belong to the same language family, i.e. stem from a common genealogical proto-language. In contrast to other contact-induced language changes like creolization or the formation of mixed languages, convergence refers to a mutual process that results in changes in all the languages involved. The term refers to changes in systematic linguistic patterns of the languages in contact (phonology, prosody, syntax, morphology) rather than alterations of individual lexical items.
Language convergence occurs in geographic areas with two or more languages in contact, resulting in groups of languages with similar linguistic features that were not inherited from each language's proto-language. These geographic and linguistic groups are called linguistic areas, or Sprachbund areas. Linguistic features shared by the languages in a language area as a result of language convergence are called areal features. In situations with many languages in contact and a variety of areal features, linguists may use the term language convergence to indicate the impossibility of locating a singular source for each areal feature. However, as the classification of linguistic areas and language convergence depends on shared areal features, linguists must distinguish between areal features resulting from convergence and internally motivated changes resulting in chance similarities between languages.
Language convergence can also occur for a particular person's grammar. It sometimes occurs in children who are acquiring a second language. Because the grammar of the child's native language is still developing the grammar patterns of the first and second language can influence each other. Singaporean students learning both English and Mandarin showed use of common Mandarin grammatical structures when speaking English.

In historical linguistics, the wave model or wave theory (German Wellentheorie) is a model of language change in which a new language feature (innovation) or a new combination of language features spreads from its region of origin, affecting a gradually expanding cluster of dialects. Dialect diffusion spreads from a given point of contact like waves on the water. The theory was intended as a substitute for the tree model, which did not seem to be able to explain the existence of some features, especially in the Germanic languages, by descent from a proto-language.
In sociolinguistics, prestige is the level of regard normally accorded a specific language or dialect within a speech community, relative to other languages or dialects. Prestige varieties are language or dialect families which are generally considered by a society to be the most "correct" or otherwise superior. In many cases, they are the standard form of the language, though there are exceptions, particularly in situations of covert prestige (where a non-standard dialect is highly valued).
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. In the family tree metaphor, a proto-language can be called a mother language. Occasionally, the German term Ursprache (from Ur- "primordial, original", and Sprache "language", ˈuːɐ̯ʃpʁaːxə) is used instead.
