Stir up noisy quarrels, we hear (5)
I believe the answer is:
rouse
'stir up' is the definition.
(I've seen this before)
'noisy quarrels we hear' is the wordplay.
'noisy quarrels' becomes 'rows' (I've seen this in another clue).
'we hear' indicates a 'sounds like' (homophone) clue.
'rows' is a homophone of 'ROUSE'.
(Other definitions for rouse that I've seen before include "Excite; awaken" , "To start" , "Make angry" , "Bumper" , "Bestir" .)
