Teacher of ape gouged bananas (9)
I believe the answer is:
pedagogue
'teacher' is the definition.
(I've seen this before)
'ape gouged bananas' is the wordplay.
'bananas' is an anagram indicator (informal term for mad).
'ape'+'gouged'='apegouged'
'apegouged' is an anagram of 'PEDAGOGUE'.
'of' acts as a link.
(Other definitions for pedagogue that I've seen before include "Strict teacher" , "Educator of young people" , "Schoolmaster" , "Dogmatic teacher" .)
