Harvest fruit to be seen again (8)
I believe the answer is:
reappear
'be seen again' is the definition.
(I've seen this before)
'harvest fruit' is the wordplay.
'harvest' becomes 'reap' ('reap' can be a synonym of 'harvest').
'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" , "Show over" , "Come into view again" , "make a comeback" , "return" .)
