Fractious (7)
I believe the answer is:
restive
'fractious' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for restive that I've seen before include "Resisting control, nervous or impatient" , "Unsettled" , "It veers around, resisting control" , "Unable to stay still" , "Fidgety, uneasy" .)
