Abundant or plentiful (7)
I believe the answer is:
opulent
This clue is a double definition.
'abundant' is the first definition.
(I've seen this in another clue)
'plentiful' is the second definition.

(Other definitions for opulent that I've seen before include "'Rich, luxurious (7)'" , "Wealthy or luxuriant" , "Prosperous" , "Wealthy, got lots of money" , "Let up on, being wealthy" .)
