He can possibly get gold, officially (5)
I believe the answer is:
mayor
'he' is the definition.
'can possibly get gold officially' is the wordplay.
I cannot quite understand how this works, but
'can' could be 'may' (synonyms) and 'may' is found in the answer.
'gold' could be 'or' ('or' is the heraldic name for gold) and 'or' is found in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for mayor that I've seen before include "Town's ceremonial head" , "Local dignitary" , "Municipal leader" , "Town council head" , "Elected city head" .)
