Timber town? (4)
I believe the answer is:
deal
This clue might be a double definition.
'timber' is the first definition.
(deal is a kind of timber)
'town?' is the second definition.
The answer and definition can be both groups as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
Can you help me to learn more?
(Other definitions for deal that I've seen before include "Give several people a hand" , "Kent resort" , "Large quantity (of wood?)" , "Wood - piece of business" , "Business arrangement in timber" .)
