Whereon, dancing, a girl gets the gold (5)
I believe the answer is:
floor
'whereon dancing' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'a girl gets the gold' is the wordplay.
'a girl' becomes 'flo' ().
'gets' says to put letters next to each other.
'the gold' becomes 'or' ('or' is the heraldic name for gold).
'flo'+'or'='FLOOR'
Can you help me to learn more?
(Other definitions for floor that I've seen before include "American's story" , "Defeat" , "Baffle, confound" , "Base of room - storey" , "Bottom surface" .)
