Provoke audible quarrels (5)
I believe the answer is:
rouse
'provoke' is the definition.
(I've seen this before)
'audible quarrels' is the wordplay.
'audible' indicates a 'sounds like' (homophone) clue.
'quarrels' becomes 'rows' ('row' can be a synonym of 'quarrel').
'rows' is a homophone of 'ROUSE'.
(Other definitions for rouse that I've seen before include "Stir from inactivity" , "Stir into action" , "Bestir" , "Cause to become awake" , "Excite; awaken" .)
