Level area with cluster of woods? (7,5)
I believe the answer is:
bowling green
'level' is the definition.
(thesaurus)
'area with cluster of woods?' is the wordplay.
'area' becomes 'green' (green is a kind of area).
'with' means one lot of letters go next to another.
'cluster of woods?' becomes 'bowling' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'green' put after 'bowling' is 'BOWLING GREEN'.
(Other definitions for bowling green that I've seen before include "Sporting area" , "Lawn for playing on" , "Where one finds woods" .)
