Did You Know?
One who is omniscient literally knows all. The word omniscient, which has been part of English since at least the beginning of the 17th century, brings together two Latin roots: the prefix omni-, meaning "all," and the verb scire, meaning "to know." You will recognize omni- as the prefix that tells all in such words as omnivorous ("eating all" or, more precisely, "eating both meat and vegetables") and omnipotent ("all-powerful"). Scire likewise has a number of other knowledge-related descendants in English, including conscience, science, and prescience (meaning "foreknowledge").
