A creole language, or simply a creole, is a stable language that has originated from a pidgin language that has been nativized (that is, acquired by children). The vocabulary of a creole language consists of cognates from the parent languages, though there are often clear phonetic and semantic shifts. On the other hand, the grammar often has original features but may differ substantially from those of the parent languages. Most often, the vocabulary comes from the dominant group and the grammar from the subordinate group, where such stratification exits. (Wikipedia)
