Pidgin language in the context of "Native language"

A lingua franca (/ˌlɪŋɡwə ˈfræŋkə/; lit. 'Frankish tongue'; for plurals see § Usage notes), also known as a bridge language, common language, trade language, auxiliary language, link language or language of wider communication (LWC), is a language systematically used to make communication possible between groups of people who do not share a native language or dialect, particularly when it is a third language that is distinct from both of the speakers' native languages.

Linguae francae have developed around the world throughout human history, sometimes for commercial reasons (so-called "trade languages" facilitated trade), but also for cultural, religious, diplomatic and administrative convenience, and as a means of exchanging information between scientists and other scholars of different nationalities. The term is taken from the medieval Mediterranean Lingua Franca, a Romance-based pidgin language used especially by traders in the Mediterranean Basin from the 11th to the 19th centuries. A world language—a language spoken internationally and by many people—is a language that may function as a global lingua franca.

Universal language may refer to a hypothetical or historical language spoken and understood by all or most of the world's people. In some contexts, it refers to a means of communication said to be understood by all humans. It may be the idea of an international auxiliary language for communication between groups speaking different primary languages. A similar concept can be found in pidgin language, which is actually used to facilitate understanding between two or more people with no common language. In other conceptions, it may be the primary language of all speakers, or the only existing language. Some religious and mythological traditions state that there was once a single universal language among all people, or shared by humans and supernatural beings.

In other traditions, there is less interest in or a general deflection of the question. The written Classical Chinese language is still read widely but pronounced differently by readers in China, Vietnam, Korea and Japan; for centuries it was a de facto universal literary language for a broad-based culture. In something of the same way Sanskrit in India and Nepal, and Pali in Sri Lanka and in Theravada countries of South-East Asia (Burma, Thailand, Cambodia) and Old Tamil in South India and Sri Lanka, were literary languages for many for whom they were not their mother tongue.
