What is the origin of omniscient?
One who is omniscient literally knows all. The word omniscient traces back to two Latin roots: omni-, meaning "all" or "universally," and the noun scientia, meaning "knowledge." You will recognize omni- as the prefix that tells all in such words as omnivorous ("eating all," or in actual use, "eating both plants and animals") and omnipotent ("all-powerful"). Scientia comes from the Latin verb scīre, meaning "to know," which likewise has a number of other knowledge-related descendants in English, including conscience, science, and prescience (meaning "foreknowledge").
