Civic official who means nothing in the army, maybe (5)
I believe the answer is:
mayor
'civic official who' is the definition.
'mayor' can be an answer for 'civic official' (I've seen this before). I am unsure of the remainder of the definition.
'nothing in the army maybe' is the wordplay.
'nothing' becomes 'O' (looks like zero - 0).
'in the' indicates putting letters inside.
'maybe' indicates an anagram.
'army' is an anagram of 'mayr'.
'o' put inside 'mayr' is 'MAYOR'.
'means' acts as a link.
Can you help me to learn more?
(Other definitions for mayor that I've seen before include "Local government head" , "Civic leader" , "Civic official" , "Elected town/city head" , "Town official" .)
