It looks like you're trying to spell epiphany, but maybe not. It means "A comprehension or perception of reality by means of a sudden intuitive realization", which could be something really random.
How Do You Spell (appithany)(appiphany)? It Means, Something Really Random, Not To Do With The Subject.
I can't find any word like that. Appiphany is a common mis-spelling for EPIPHANY, which means "manifestation" or "showing." It was originally used to refer to the revelation of the infant Jesus to the Magi, and is commonly used to refer to any moment of enlightenment or clarity.
As for something random, it is true that the Greek prefix apo- does mean "away from" but I can't find anything meaning "away from the subject." The nearest I can think of is APOCRYPHAL, which means mythical, invented or untrue (from the Biblical Apocrypha, which refers to books rejected for inclusion in the official Bible.)
I hope this helps and that you find xactly what youre looking for.
