Witty saying (7)
I believe the answer is:
epigram
'witty saying' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for epigram that I've seen before include "Clever remark" , "Pithy remark - grim ape (anag)" , "Pithy and witty saying" , "Quip, witty saying" , "Witty poem" .)
