نیم‌زبان

Also known as pidgins

A pidgin , or pidgin language, is a grammatically simplified form of contact language that develops between two or more groups of people that do not have a language in common: typically, its vocabulary and grammar are limited and often drawn from several languages. 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).
