omniscient

The Latin roots are transparent once you see them. "Omnis" meant "all" in classical Latin, and "sciens" was the present participle of "scire," meaning "to know." The compound "omnisciens" did not appear in classical Latin itself. Medieval Christian theologians coined it in the early centuries of the Common Era to describe a quality they attributed exclusively to God: awareness that takes in all times and places without remainder.

The root "scire" goes back further still. Linguists trace it to the Proto-Indo-European root skey-, meaning to cut or separate. To know something, in this deep etymology, is to cut it apart from everything else and hold it distinctly in mind. That same root gave Latin "scissor" (one who cuts) and eventually English "scissors" and "schism." Knowing and dividing share a single ancestry.

English borrowed "omniscient" in the early seventeenth century, around 1604 by most dictionaries' reckoning. The word arrived already theological: it described divine knowing, the kind that grasps all contingencies at once. John Milton used it in "Paradise Lost" (1667) to describe God's perfect awareness. The word's first English home was church Latin and Protestant theology, where it served primarily as an attribute in catechisms.

By the nineteenth century, "omniscient" had made the leap into secular literary criticism. Critics began using "omniscient narrator" to describe the godlike point of view in novels that seemed to know every character's thoughts simultaneously. Henry James debated this technique in his prefaces, and later narratologists formalized the usage. The word kept its theological resonance while gaining a second life in craft discussions of prose fiction.
