Scot's fine line in affray (5)
I believe the answer is:
brawl
'affray' is the definition.
(I've seen this before)
'scot's fine line' is the wordplay.
I cannot quite understand how this works, but
'fine' could be 'braw' (synonyms) and 'braw' is found in the answer.
'line' could be 'l' (used when specifying particular lines from a poem) and 'l' is found in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'in' is the link.
Can you help me to learn more?
(Other definitions for brawl that I've seen before include "Noisy quarrel" , "Abounding" , "Rowdy scuffle" , "Affray" , "dispute" .)
