Wealthy put Noel off (7)
I believe the answer is:
opulent
'wealthy' is the definition.
(opulent means extravagantly wealthy)
'put noel off' is the wordplay.
'off' is an anagram indicator.
'put'+'noel'='putnoel'
'putnoel' is an anagram of 'OPULENT'.
(Other definitions for opulent that I've seen before include "extremely elegant" , "Wealthy, got lots of money" , "Ostentatiously rich" , "Prosperous" , "Wealthy or luxuriant" .)
