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 rest of the definition.
'nothing in the army maybe' is the wordplay.
'nothing in' becomes 'o' (I've seen this in other clues).
'maybe' indicates an anagram.
'o'+'army'='oarmy'
'oarmy' with letters rearranged gives 'MAYOR'.
'means' is the 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" .)
