Growling about tiff (3)
I believe the answer is:
row
'tiff' is the definition.
(thesaurus)
'growling about' is the wordplay.
'about' says the answer is hidden in the clue.
'ROW' is hidden in the letters of 'growling'.
(Other definitions for row that I've seen before include "sequence" , "Barney - rank" , "Use an oar" , "File" , "Propel boat with manual aids" .)
