Cosy up and hang round with hired killer (10)
I believe the answer is:
gunslinger
'hired killer' is the definition.
(I know that gunslinger is a subclass of hired murderer)
'cosy up and hang round' is the wordplay.
'cosy' becomes 'snug' (synonyms).
'up' is a reversal indicator (in down clue: letters go upwards).
'and' says to put letters next to each other.
'hang round' becomes 'linger' (I've seen this in another clue. I am not sure about the 'round' bit.).
'snug' back-to-front is 'guns'.
'guns'+'linger'='GUNSLINGER'
'with' is the link.
Can you help me to learn more?
(Other definitions for gunslinger that I've seen before include "One with a hand weapon" , "Armed bandit" , "Armed cowboy perhaps" , "shot by him?" , "user of weapon" .)
