Sketch; coarse (5)
I believe the answer is:
rough
I believe this is a double definition.
'sketch' is the first definition.
(thesaurus)
'coarse' is the second definition.
(similar in meaning)
(Other definitions for rough that I've seen before include "Nasty" , "Boisterous; uneven" , "scratchy" , "'Coarse, rugged (5)'" , "Not gentle or restrained" .)
