Vulgarian censure overturned? Say pub closed early (7)
I believe the answer is:
parvenu
'vulgarian' is the definition.
(thesaurus)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for parvenu that I've seen before include "Johnny-come-lately, upstart" , "One coming" , "Arriviste" , "Nouveau riche" , "Newly rich person" .)
