Wake up hearing arguments (4)
I believe the answer is:
rows
'arguments' is the definition.
(I've seen this before)
'wake up hearing' is the wordplay.
'wake up' becomes 'rouse' (rouse can mean to wake up).
'hearing' shows a homophone (sound like).
'rouse' is a homophone of 'ROWS'.
(Other definitions for rows that I've seen before include "Rackets" , "Tiers" , "Uses oars" , "Arguments" , "Banks" .)
