Unusually dishonest sybarites (9)
I believe the answer is:
hedonists
'sybarites' is the definition.
The answer and definition can be both people as well as being plural nouns.
Maybe you can see a link between them that I don't see?
'unusually dishonest' is the wordplay.
'unusually' indicates an anagram.
'dishonest' is an anagram of 'HEDONISTS'.
Can you help me to learn more?
(Other definitions for hedonists that I've seen before include "lotus-eaters" , "self-indulgent types" .)
