Lavish, rich (7)
I believe the answer is:
opulent
This clue is a double definition.
'lavish' is the first definition.
(I've seen this before)
'rich' is the second definition.
(similar in meaning)
(Other definitions for opulent that I've seen before include "Well-to-dp. affluent" , "Rich, luxuriant" , "Ostentatiously costly and luxurious" , "No let-up (anag)" , "Wealthy, possessing riches" .)
