Gold and diamonds enthralling single female, leading to opening (7)
I believe the answer is:
orifice
'opening' is the definition.
(synonyms)
'gold and diamonds enthralling single female leading' is the wordplay.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'and' is a charade indicator (letters next to each other).
'diamonds' becomes 'ice' (slang term for diamonds).
'enthralling' is an insertion indicator.
'single female leading' becomes 'fi' (I can't explain this - if you can you should believe this answer much more).
'ice' going around 'fi' is 'ifice'.
'or'+'ifice'='ORIFICE'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for orifice that I've seen before include "Hole in the head, perhaps?" , "Bodily hole" , "Bodily opening, mouth of cavity" , "provided by gold and diamonds" , "8 [OPENING]" .)
