King rows and bellows (5)
I believe the answer is:
roars
'bellows' is the definition.
('roar' can be a synonym of 'bellow')
'king rows' is the wordplay.
'king' becomes 'R' (abbreviation for rex, king in Latin).
'rows' becomes 'oars' (I've seen this before).
'r'+'oars'='ROARS'
'and' is the link.
(Other definitions for roars that I've seen before include "Bellows, hollers" , "Bellows like a bull" , "Sounds like a lion" , "Deep bellows" , "Calls like lion" .)
