Philosophically and theologically, it indicates something, e. g., the universe, that was created from outside of time.

In other contexts, it often refers to beginner or training courses. In law, it refers to a thing being true from its beginning or from the instant of the act, rather than from when the court declared it so. Likewise, an annulment is a judicial declaration of the invalidity or nullity of a marriage ab initio: the so-called marriage was "no thing" (Latin: nullius, from which the word "nullity" derives) and never existed, except perhaps in name only.
