Choice article in heraldic gold (5)
I believe the answer is:
other
'choice' is the definition.
Both the definition and answer are adjectives. Maybe they are linked in a way I don't understand?
'article in heraldic gold' is the wordplay.
'article' becomes 'the' (the definite article in English).
'in' indicates putting letters inside.
'heraldic gold' becomes 'or' ('or' is the heraldic name for gold. I am not sure about the 'heraldic' bit.).
'the' put within 'or' is 'OTHER'.
Can you help me to learn more?
(Other definitions for other that I've seen before include "Different; alternate" , "Very unusual" , "Alternate; additional" , "Different, disparate" , "Different, alternative" .)
