Gathers pears, possibly (5)
I believe the answer is:
reaps
'gathers' is the definition.
(reaping is a kind of gathering)
'pears possibly' is the wordplay.
'possibly' is an anagram indicator.
'pears' with letters rearranged gives 'REAPS'.
(Other definitions for reaps that I've seen before include "Harvests (a crop)" , "Harvests with strange spear" , "crops" , "Cuts, gathers grain" , "Gleans or harvests" .)
