Principle relating to a culture that’s unnamed? (5)
I believe the answer is:
ethic
'principle' is the definition.
(ethic is a kind of principle)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for ethic that I've seen before include "Ideology" , "System of principles" , "set of morals" , "Principles accepted by a social group" , "Moral code" .)
