A fellow with the gift of the gab and rich (8)
I believe the answer is:
affluent
'rich' is the definition.
(similar in meaning)
'a fellow with the gift of the gab' is the wordplay.
'fellow with' becomes 'f' (I've seen this in other clues).
'the gift of the gab' becomes 'fluent' (I can't explain this - if you can you should believe this answer much more).
'a'+'f'+'fluent'='AFFLUENT'
'and' acts as a link.
Can you help me to learn more?
(Other definitions for affluent that I've seen before include "Well-to-do, got lots of money" , "Flute fan may be wealthy" , "Rich; flowing freely" , "Well-off" , "Wealthy - abundant" .)
