Brusque and surly (5)
I believe the answer is:
gruff
'brusque and surly' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for gruff that I've seen before include "Abrupt in manner - rough and low in pitch" , "Sounding rough" , "(Of voice) rough, low" , "Abrupt in sound or manner" , "Husky" .)
