Wood in model, maybe (3)
I believe the answer is:
elm
'wood' is the definition.
(elm is a kind of wood)
'in model maybe' is the wordplay.
'in' indicates the answer is hidden within the clue.
'ELM' is hidden in the letters of 'model maybe'.
(Other definitions for elm that I've seen before include "Mel's tree" , "Forest tree" , "one has a trunk and leaves" , "Tall shade tree" , "Native British tree" .)
