Opinion given one way or another (5)
I believe the answer is:
tenet
I believe this is a double definition.
'opinion' is the first definition.
(I've seen this before)
'one way or another' is the second definition.
'given' is the link.
(Other definitions for tenet that I've seen before include "you may believe in it" , "Doctrine; principle held" , "It's believed" , "Dogma or principle" , "Belief held as true" .)
