Saint and sinner in a newspaper cartoon (5)
I believe the answer is:
strip
'cartoon' is the definition.
(I know that strip is a type of cartoon)
'saint and sinner in a newspaper' is the wordplay.
'saint' becomes 'st' (abbreviation).
'and' means one lot of letters go next to another.
'sinner in a newspaper' becomes 'rip' (I can't explain this - if you can you should believe this answer much more).
'st'+'rip'='STRIP'
Can you help me to learn more?
(Other definitions for strip that I've seen before include "Plunder" , "Take off clothing" , "footballers' outfit" , "Series of cartoon pictures - undress salaciously" , "Lay bare" .)
