Come back to gather fruit (8)
I believe the answer is:
reappear
'come back' is the definition.
(to reappear is to come back again)
'gather fruit' is the wordplay.
'gather' becomes 'reap' (reaping is a kind of gathering).
'fruit' becomes 'pear' (pear is a kind of fruit).
'reap'+'pear'='REAPPEAR'
'to' is the link.
(Other definitions for reappear that I've seen before include "Turn up again" , "spring up again?" , "make a comeback" , "crop up again" , "return" .)
