Fruit got from broken crate found in square (9)
I believe the answer is:
nectarine
'fruit' is the definition.
(I know that nectarine is a fruit)
'broken crate found in square' is the wordplay.
'broken' indicates anagramming the letters.
'found in' is an insertion indicator.
'square' becomes 'nine' (nine is a square number).
'crate' anagrammed gives 'ectar'.
'ectar' put within 'nine' is 'NECTARINE'.
'got from' is the link.
(Other definitions for nectarine that I've seen before include "type of tree" , "Peach-like fruit" , "Trace nine to a kind of peach" , "Kind of peach with thin skin and no down" , "Fruit - aren't nice (anag)" .)
