Removing article from wrapping is rude (9)
I believe the answer is:
insulting
'rude' is the definition.
(thesaurus)
'removing article from wrapping' is the wordplay.
I cannot quite see how this works, but
'from' could be 'in' (I've seen this in other clues) and 'in' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'is' acts as a link.
(Other definitions for insulting that I've seen before include "What offender's doing" , "Offensive" , "Treating with disrespect" .)
