Cross and quarrelsome (9)
I believe the answer is:
fractious
'cross and quarrelsome' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for fractious that I've seen before include "Petulant; awkward" , "Difficult to control; irritable" , "Grumpy" , "Cross and quarrelsome" , "Testy" .)
