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 within the answer.
'saint' could be 's' and 's' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
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" .)
