Fretful; cross (7)
I believe the answer is:
peevish
I believe this is a double definition.
'fretful' is the first definition.
(thesaurus)
'cross' is the second definition.
(I've seen this in another clue)
(Other definitions for peevish that I've seen before include "In irritable state" , "Cranky, easily annoyed" , "Easily irritated or annoyed" , "Spiteful" , "Fractious" .)
