Stir up arguments in speech (5)
I believe the answer is:
rouse
'stir up' is the definition.
(I've seen this before)
'arguments in speech' is the wordplay.
'arguments' becomes 'rows' (I've seen this in other clues).
'in speech' shows a homophone (sound like).
'rows' sounds like 'ROUSE'.
(Other definitions for rouse that I've seen before include "Cause to wake up and come alert" , "Cause to wake up, stimulate" , "cause to wake or to become active" , "Get going" , "Stir up; excite" .)
