Fruit held by adorable monkeys (5)
I believe the answer is:
lemon
'fruit' is the definition.
(lemon is a kind of fruit)
'held by adorable monkeys' is the wordplay.
'held by' says the answer is hidden in the clue.
'LEMON' is hidden within 'adorable monkeys'.
(Other definitions for lemon that I've seen before include "something defective" , "stinker" , "definitely not a peach" , "Pale yellow, as of citrus fruit" , "Melon (anag)" .)
