Returned to cut some punctuation (9)
I believe the answer is:
backslash
'punctuation' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'returned to cut' is the wordplay.
'returned' becomes 'back' (I've seen this in other clues).
'to cut' becomes 'slash' (slashing is a kind of cutting).
'back'+'slash'='BACKSLASH'
'some' acts as a link.
Can you help me to learn more?
(Other definitions for backslash that I've seen before include "One leaning to the left" , "//www.crosswordgiant.com/crossword-clue/1252911/" , "line on computer screen" , "Mark" , "character" .)
