Cancel New York reception? (4)
I believe the answer is:
undo
'cancel' is the definition.
(I've seen this in another clue)
'new york reception?' is the wordplay.
'new york' becomes 'un' (I am not sure about this - if you are sure you should believe this answer much more).
'reception?' becomes 'do' (I've seen this in other clues).
'un'+'do'='UNDO'
Can you help me to learn more?
(Other definitions for undo that I've seen before include "Unfasten - destroy" , "Ruin, destroy" , "Release button, knot etc" , "Unfasten or annul" , "Take back" .)
