Nick what capable people are up to (7)
I believe the answer is:
scratch
'nick' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for scratch that I've seen before include "given no advantage" , "handle superficial irritation" , "Deal with itch - cancel entry" , "cancel > test > money" , "Score with a sharp point" .)
