Graze, abrasion (6)
I believe the answer is:
scrape
I believe this is a double definition.
'graze' is the first definition.
(I've seen this before)
'abrasion' is the second definition.
(I know that abrasion can be written as scrape)
(Other definitions for scrape that I've seen before include "Grate, scratch" , "Difficult predicament" , "hole" , "Abrasion or mischievous escapade" , "Bark" .)
