Chop some of the wood (3)
I believe the answer is:
hew
'chop' is the definition.
(to hew is to chop or cut down)
'some of the wood' is the wordplay.
'some of' says the answer is hidden in the clue.
'HEW' can be found hidden inside 'the wood'.
(Other definitions for hew that I've seen before include "Carve out of wood or stone" , "Chop (wood)" , "Carve with axe" , "Shape wood, as with an axe" , "Chop or hack at" .)
