Wave model
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.
Lexifier
A lexifier is the language that provides the basis for the majority of a pidgin or creole language's vocabulary (lexicon). Often this language is also the dominant, or superstrate language, though this is not always the case, as can be seen in the historical Mediterranean Lingua Franca. In mixed languages, there are no superstrates or substrates, but instead two or more adstrates. One adstrate still contributes the majority of the lexicon in most cases, and would be considered the lexifier.
