Cherry or walnut (4)
I believe the answer is:
wood
I believe this clue is a double definition.
'cherry' is the first definition.
(thesaurus)
'walnut' is the second definition.
(thesaurus)
(Other definitions for wood that I've seen before include "Driver, perhaps" , "'Under Milk - - ' (lit.)" , "Material from trees" , "Lots of trees" , "Forest - golf club - biased bowl" .)
