It is most commonly employed in situations such as trade, or where both groups speak languages different from the language of the country in which they reside (but where there is no common language between the groups). Fundamentally, a pidgin is a simplified means of linguistic communication, as it is constructed impromptu, or by convention, between individuals or groups of people. A pidgin is not the native language of any speech community, but is instead learned as a second language. A pidgin may be built from words, sounds, or body language from multiple other languages and cultures. They allow people who have no common language to communicate with each other. Pidgins usually have low prestige with respect to other languages.    Given the information, choose the subject and object entities that have the relation of 'instance of'.
