Trouble from scratch (6)
I believe the answer is:
scrape
I believe this is a double definition.
'trouble' is the first definition.
(thesaurus)
'scratch' is the second definition.
(I know that scratch can be written as scrape)
'from' is the link.
(Other definitions for scrape that I've seen before include "Take the surface off" , "Thinly-spread butter" , "Slight injury - close shave?" , "Awkward situation - be very economical" , "Make clean or smooth by passing hard edge across" .)
