lexifier (plural lexifiers)

1. (linguistics, lexicography) The language of a pidgin or creole that serves as the basis for most of its vocabulary.

     A great deal of linguistic evidence reveals that creole creators transformed the lexifier in a fashion unexplainable as just hybridization, but well known from studies of pidginization and second-language acquisition.
