In the thick crowd find the perfection re morals (5)
I believe the answer is:
ethic
'morals' is the definition.
(thesaurus)
'in the thick crowd' is the wordplay.
'in' indicates a hidden word.
'ETHIC' is hidden within 'the thick crowd'.
'find the perfection re' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for ethic that I've seen before include "Moral practice" , "Moral principle" , "Ideology" , "Set of moral values" , "System of principles" .)
