Gather some more apples (4)
I believe the answer is:
reap
'gather' is the definition.
(reaping is a kind of gathering)
'some more apples' is the wordplay.
'some' says the answer is hidden in the clue (some parts of the word are used).
'REAP' can be found hidden inside 'more apples'.
(Other definitions for reap that I've seen before include "Harvest (a crop)" , "'As you sow, so shall you . . . .'" , "Derive as advantage" , "Cut or gather (a harvest)" , "''As you sow, so you . . . .'' (4)" .)
