Pidgin languages are generally languages which are more or less rudimentary languages developing in situations of contacts between two different cultures, one of them dominant in the contact situation, with the use of such languages restricted to certain limited contacts such as trading, plantation work involving the employment of indigenous labour, master-servant relationships, and similar types of contact situations. Much of the vocabulary of a pidgin language consists of elements of the language of the dominant culture in a more or less distorted, and often semantically changed, form with elements from the language of the non-dominant culture playing a less important part in its vocabulary. Its structural features do not as a rule reflect structural characteristics of the language of the dominant culture, unless the languages of both the dominant and the non-dominant culture are closely related and structurally very similar, though even in such situations quite significant deviations from the structural set-up of the language of the dominant culture can be observed in the pidgin language. Some to many of the structural features of a pidgin language may reflect features of the language of the non-dominant culture but, in pidgin languages, a number of unique structural and grammatical features can be observed which appear to reflect some basic simplifications in language use in contact situations between speakers of different languages. In any event, in the usual type of pidgin language, the overall vocabulary is small and limited in its usefulness to the specific types of contact situations in which the language is used and its grammatical complexity is greatly reduced when compared with both the language of the dominant culture and the nondominant culture. Also, as a rule, the sound system of a pidgin language constitutes a considerable simplification when compared with the sound system of both these languages.
