How do you say appreciate in creole?

Actually, there is no such language as "Creole."

The Word Creole describes any language that is a stable, full-fledged language originating from a pidgin (which is a language composed of two or more unrelated languages).

There are over 100 completely different creoles still spoken in the world today. Some of most common creolized languages are Haitian Creole, Louisiana Creole, Jamaican Creole, and Tok Pisin.
