Gold in toilet facility for the president of the yacht club! (9)
I believe the answer is:
commodore
'for the president of the yacht club' is the definition.
(a yacht club's president is called a commodore)
'gold in toilet' is the wordplay.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'in' indicates putting letters inside.
'toilet' becomes 'commode' (synonyms).
'or' put into 'commode' is 'COMMODORE'.
'facility' acts as a link.
This may not be correct. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for commodore that I've seen before include "senior officer" , "Naval rank junior to rear-admiral" , "President of a yacht club" , "Naval officer" , "officer, surely?" .)
