Scottish fine Liberal for affray (5)
I believe the answer is:
brawl
'affray' is the definition.
(I've seen this before)
'scottish fine liberal' is the wordplay.
'scottish fine' becomes 'braw'.
'liberal' becomes 'l' (abbreviation).
'braw'+'l'='BRAWL'
'for' is the link.
(Other definitions for brawl that I've seen before include "Melee" , "Unruly fight" , "Rowdy fight" , "Riotous fight" , "Quarrel noisily" .)
