Grating — abrasive (8)
I believe the answer is:
scratchy
This clue is a double definition.
'grating' is the first definition.
(I know that grating can be written as scratchy)
'abrasive' is the second definition.
(I know that abrasive can be written as scratchy)
(Other definitions for scratchy that I've seen before include "Like many an old record" , "Itchy" , "Irritable" , "bad-tempered" , "marked by abrasions" .)
