What is the difference between lingua franca and a pidgin language?
A lingua franca is any language used as a shared standard to communicate between people of different native languages. A pidgin is specifically a made-up simplified language, often with elements from two or more languages, to allow communication between people of different native languages. A pidgin might be used a lingua franca, but a lingua franca needn’t be a pidgin. The original Lingua Franca used in Mediterranean trading was largely Italian.
