Often ethics disguise dogma (5)
I believe the answer is:
tenet
'dogma' is the definition.
(synonyms)
'often ethics disguise' is the wordplay.
'TENET' is hidden in amongst the letters.
But, I am uncertain how this is indicated.
Can you help me to learn more?
(Other definitions for tenet that I've seen before include "Fundamental belief" , "A belief or credo - it's a palindrome" , "Teaching" , "Doctrine held to be true" , "Canon" .)
