Come back to harvest fruit (8)
I believe the answer is:
reappear
'come back' is the definition.
The definition and answer can be both related to change as well as being verbs in their base form.
Perhaps there's an association between them I don't understand?
'harvest fruit' is the wordplay.
'harvest' becomes 'reap' (synonyms).
'fruit' becomes 'pear' (pear is a kind of fruit).
'reap'+'pear'='REAPPEAR'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for reappear that I've seen before include "return" , "Be seen again" , "make a comeback" , "Turn up again" , "Come into view again" .)
