Pinch bark (6)
I believe the answer is:
scrape
I believe this clue is a double definition.
'pinch' is the first definition.
(thesaurus)
'bark' is the second definition.
(thesaurus)
(Other definitions for scrape that I've seen before include "jar" , "Abrade - predicament" , "Graze - awkward predicament" , "Fix - grate" , "Just manage to achieve (exam pass)" .)
