I think you mean what is the difference between language and tongue, you see people use those two words to mean the same thing (language) for example some people may ask you "what is your mother tongue?" or native tongue or first language etc etc and they all refer to language. But usually it is more common to say language, cause tongue is more used only to ask the question "what is your mother tongue", refering to your first language or native language.
