Rough — brusque (5)
I believe the answer is:
gruff
This clue is a double definition.
'rough' is the first definition.
(thesaurus)
'brusque' is the second definition.
(I've seen this in another clue)
(Other definitions for gruff that I've seen before include "Surly -- rough-spoken" , "Harsh - brusque" , "Abrupt in manner - rough and low in pitch" , "Rasping - ungracious" , "Hoarse" .)
