Clever humor (3)
I believe the answer is:
wit
'clever humor' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for wit that I've seen before include "Intelligence; humorist" , "Cleverness with words and ideas" , "Humour; wag" , "Funny person" , "Ingenuity or verbal fun" .)
