A lingua franca is a language used between people who do not have a common language. English is often used as a lingua franca in international business transactions. A pidgin is a language that has a small vocabulary and is a combination and distortion of two or more languages. For example, pidgin English, a combination between English and indigenous languages, is used in Papua New Guinea between English-speaking and indigenous people. Most pidgins are lingua francas but not all lingua francas are pidgins.
