The meaning of some "omni-" words
Because of the fact that it's an omnilogy website, I think it's necessary to explain exactly over here the meaning of the words with "omni-", i. e. the "omni-" words. We mentioned some of them more or less before. Now I'll right more concretely about each of them (and some others).
Omnilogy is the science (or just the knowledge) about everything. It's like a synonym of the word encyclopedism ([enˌsaɪklə'pi:dɪzəm]; [ɪnˌsaɪklə'pidɪzəm]).
The word omnipresence means the state of being widespread or constantly encountered; to be everywhere (at the same time). This is the meaning of the word. If it's really possible for somebody or something is another question.
The word omnipotence means the quality of having unlimited power, unlimited abilities. This is the meaning of the word. If it's really possible is just another question.
The word omniscient means "knowing everything".
The word omnivore ([ˈɒmnɪvɔː(r)]; [ˈɑːmnɪvɔːr]) means somebody (human or another life thing) that eats "everything", i. e. food of both plant and animal origin.
The word omnicompetent means someone/something who/which is able to judge and/or deal with all matters. If it's really possible to exist is another question.
Well, the word-forming element "omni-"'s meaning is "all" and it has a Latin origin.
