The word omnific is an adjective that describes a power or force that is capable of creating everything or bringing the entire universe into existence.
The word omnific is used most commonly in religious and philosophical writings, and in poetry. It usually refers to an all-creating divine or natural power. But the word might pop up elsewhere; for example, you could refer to players of a video game as omnific if they are able to create an entire city or universe within the game world. Similarly, a fantasy or science fiction author might be referred to as omnific, as a "creator of worlds." The Latin roots of omnific are omni, "all," and facere, "to make."
