Quarrel at home for light meal (6)
I believe the answer is:
tiffin
'light meal' is the definition.
(I've seen this before)
'quarrel at home' is the wordplay.
'quarrel' becomes 'tiff' (informal term for an argument).
'at home' becomes 'in' (similar in meaning).
'tiff'+'in'='TIFFIN'
'for' acts as a link.
(Other definitions for tiffin that I've seen before include "(Anglo Indian) lunch" , "Snack, light meal (dated)" , "Light Indian repast" , "Lunch (British Raj)" , "Indian midday meal" .)
