Religionym and confessionym

Religionym (from Latin: religio / religion, and Greek: ὄνομα / name) and confessionym (from Latin: confessio / confession, and Greek: ὄνομα / name) are neologisms that have several distinct meanings, generally related (from the semantic point of view) to religious (confessional) terminology, but are (in their specific meanings) defined and used differently among scholars. As a consequence of a wide variety of uses, specific meanings of those terms can be mutually distinct, but also overlapping.
