how to use explicit and explicitly ?

Question

when i should use explicit and when i should use explicitly ?

Answer 1

Explicit is an adjective, use it when describing a person, place, or thing.
Explicitly is an adverb, use it when describing an action.

Answer 2

The word explicit is an adjective meaning "fully revealed", used to describe something (usually a warning as is "Warning: Explicit Content).

Explicitly is an adverb (the 'ly' is dead giveaway) meaning "clearly". As is "I explicitly (clearly) told you to do your homework before going out, Son!"
I hope this isn't too confusing. You can find the meanings here:
