With a need to unwind, a gentleman about to mooch (7)
I believe the answer is:
meander
'to mooch' is the definition.
(thesaurus)
'with a need to unwind a gentleman' is the wordplay.
I cannot quite see how this works, but
'with' could be 'and' and 'and' is present in the answer.
The remaining letters 'meer' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'about' is the link.
Can you help me to learn more?
(Other definitions for meander that I've seen before include "turning thereon?" , "keep dodging the point" , "Ramble about aimlessly" , "Wind about or wander here and there" , "Wander without aim or direction" .)
