Spurn quiet French article (4)
I believe the answer is:
shun
'spurn' is the definition.
(thesaurus)
'quiet french article' is the wordplay.
'quiet' becomes 'sh' (both can be said to tell someone to be quiet).
'french article' becomes 'un' (indefinite article in French).
'sh'+'un'='SHUN'
(Other definitions for shun that I've seen before include "Persistently avoid" , "military command" , "Avoid contact" , "Deliberately avoid" , "Spurn; avoid" .)
