Any language created out of a mixture of other languages as a means of communication between speakers of different tongues. Pidgins have rudimentary grammars and restricted vocabulary, serving as auxiliary contact languages. They are improvised rather than learned natively.

Pidgins can develop to become Creole languages. This requires the pidgin to be learned natively by children, who then generalize the features of the pidgin into a fully-formed, stabilized grammar.
