This document discusses pidgin and creole languages. It defines pidgin as a simplified language that develops for communication between groups that speak different languages. Pidgins have no native speakers and basic grammar. Creoles evolve from pidgins and become the native language of a community, with more complex grammar and phonology. Examples provided are Tok Pisin, Hawai'i Creole English, and Jamaican Creole. Pidgins are used for trade and practical communication while creoles take on properties of full languages.
