Can they provide shoemakers with supper? (6)
I believe the answer is:
uppers
'can they' is the definition.
The definition suggests a plural noun which matches the answer.
'shoemakers with supper?' is the wordplay.
'supper' can be anagrammed to 'UPPERS'.
But, I'm unsure how this is indicated.
'provide' is the link.
Can you help me to learn more?
(Other definitions for uppers that I've seen before include "Out of luck, one may be on these" , "pills" , "Drugs" , "the poor are on?" , "Skint when on these" .)
