Come again to gather fruit (8)
I believe the answer is:
reappear
'come again' is the definition.
(thesaurus)
'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' acts as a link.
(Other definitions for reappear that I've seen before include "crop up again" , "Be seen again" , "return" , "spring up again?" , "make a comeback" .)
