The difficulty having so little butter (6)
I believe the answer is:
scrape
'the difficulty' is the definition.
(I've seen this in another clue)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for scrape that I've seen before include "Scratch the surface in a predicament" , "Clean with something sharp" , "jar" , "Just manage to achieve (exam pass)" , "Graze - awkward predicament" .)
