Type of comedy (9)
I believe the answer is:
slapstick
'type of comedy' is the definition.
(I know that slapstick is a type of comedy)
This is all the clue.
(Other definitions for slapstick that I've seen before include "Crude form of comedy" , "Unsubtle comedy" , "unsophisticated humour" , "Simple comic act" , "Boisterous comedy based on actions rather than words" .)
