Civic dignitary for a month – or more? (5)
I believe the answer is:
mayor
'civic dignitary' is the definition.
(I've seen this before)
'month or more?' is the wordplay.
'month' becomes 'may' (May is an example).
'more?' is a charade indicator (letters next to each other) (some letters added to the previous ones).
'may'+'or'='MAYOR'
'for a' is the link.
(Other definitions for mayor that I've seen before include "First citizen of a city" , "Municipal leader" , "Town's ceremonial head" , "Town dignitary" , "Town official" .)
