Scottish slope (4)
I believe the answer is:
brae
'scottish slope' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for brae that I've seen before include "Bare on Scottish hillside" , "Scottish hill slope" , "Slope on hill or in glen" , "Sloping hillside" , "Steep bank or hillside" .)
