Fruit cocktail chunk (4)
I believe the answer is:
pear
'fruit cocktail chunk' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for pear that I've seen before include "Conference, perhaps" , "Juicy fruit" , "Fruit sounds like two of a kind" , "Tapering fleshy fruit - reap it" , "William, maybe" .)
