Crossword Genius

Reversible principle? (5)

Ross

I believe the answer is:

tenet

This clue is a double definition.

'reversible' is the first definition.

'principle?' is the second definition.
(a tenet is a principle or value)

(Other definitions for tenet that I've seen before include "Teaching" , "It's believed" , "A belief or credo - it's a palindrome" , "Item of belief" , "Palindromic principle or belief" .)

I've seen this clue in The Mirror.
