Loaded footballers turned voluble (8)
I believe the answer is:
affluent
'loaded' is the definition.
(loaded can mean very rich)
'footballers turned voluble' is the wordplay.
'footballers' becomes 'FA' (Football Association abbreviation).
'turned' says the letters should be written backwards.
'voluble' becomes 'fluent' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'fa' in reverse letter order is 'af'.
'af'+'fluent'='AFFLUENT'
Can you help me to learn more?
(Other definitions for affluent that I've seen before include "Well-off" , "Very well off, quite rich" , "Well-to-do, wealthy" , "Wealthy - abundant" , "Loaded" .)
