Pidgins may start out as or become trade languages, such as Tok Pisin. Trade languages can eventually evolve into fully developed languages in their own right, such as Swahili, distinct from the languages they were originally influenced by. Trade languages and pidgins can also influence an established language's vernacular, especially amongst people who are directly involved in a trade where that pidgin is commonly used, which can alternatively result in a regional dialect being developed.
