Question

another one of my questions...What is the difference between Colloquial Expression and Colloquial Language?

Answer 1

Answer:

So in a nutshell, both colloquialism and slang are spoken forms of the language. Both use informal words and expressions. Slang is more informal than colloquial language. Slang is predominantly used by certain groups of people while colloquial language is used in every day speech by ordinary people.
