Scratch, abrasion (6)
I believe the answer is:
scrape
I believe this is a double definition.
'scratch' is the first definition.
(I know that scratch can be written as scrape)
'abrasion' is the second definition.
(I know that abrasion can be written as scrape)
(Other definitions for scrape that I've seen before include "What violinist does" , "Grate - predicament" , "Save with difficulty - sounds abrasive" , "Just manage to achieve (exam pass)" , "Embarrassing predicament" .)
