Growling about argument (3)
I believe the answer is:
row
'argument' is the definition.
(to row is to argue)
'growling about' is the wordplay.
'about' indicates a hidden word (the clue goes around or about the answer).
'ROW' is hidden in the letters of 'growling'.
(Other definitions for row that I've seen before include "Propel boat by manual means" , "Use an oar" , "Fight in a queue?" , "Altercation" , "File" .)
