Maybe bow's shot showing expertise in Sherwood? (8)
I believe the answer is:
forestry
'expertise in sherwood?' is the definition.
The answer and definition can be both related to thinking as well as being singular nouns.
Maybe there's a link between them I don't understand?
'maybe bow's shot' is the wordplay.
I cannot really see how this works, but
'bow's' could be 'fores' ('fore' can be a synonym of 'bow') and 'fores' is located in the answer.
'shot' could be 'try' (both can mean an attempt) and 'try' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'showing' is the link.
Can you help me to learn more?
(Other definitions for forestry that I've seen before include "(exemplary) elder management?" , "The planting and management of timber" , "Science of trees" , "woodwork" , "expanse of trees" .)
