Did You Know?
One who is "omniscient" literally "knows all." The word, 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").
