/om'neuh prez"euhnt/, adj.
present everywhere at the same time: the omnipresent God.
[1600-10; < ML omnipraesent- (s. of omnipraesens), equiv. to L omni- OMNI- + praesent- PRESENT1]
Syn. OMNIPRESENT, UBIQUITOUS refer to the quality of being everywhere. OMNIPRESENT emphasizes in a lofty or dignified way the power, usually divine, of being present everywhere at the same time, as though all-enveloping: Divine law is omnipresent. UBIQUITOUS is applied to that which seems to appear in many and all sorts of places, or in an undignified or humorous way is "all over the place," often when unwanted: A bore seems to be ubiquitous.
