Avoid quiet one in Marseilles (4)
I believe the answer is:
shun
'avoid' is the definition.
(I know that shun is a more specific form of the action avoid)
'quiet one in marseilles' is the wordplay.
I cannot really see how this works, but
'quiet' could be 'sh' (both can be said to tell someone to be quiet) and 'sh' is found within the answer.
'one' could be 'un' (northern English dialect form of 'one') and 'un' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for shun that I've seen before include "military command" , "Cold-shoulder" , "Avoid, ignore" , "Avoid, keep away from" , "Ostracise" .)
