Maybe remove dust from behind Saint Nick (5)
I believe the answer is:
swipe
'nick' is the definition.
(I know that swipe is a more specific form of nick)
'maybe remove dust from behind saint' is the wordplay.
I cannot really see how this works, but
'remove' could be 'wipe' (I've seen this in another clue) and 'wipe' is found in the answer.
'saint' could be 's' and 's' is located in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for swipe that I've seen before include "Blow - nick" , "Process (credit card); steal (colloq.)" , "Put (card) through reader; take without asking" , "Pilfer" , "Steal; pass a card through a reader" .)
