## Origin

The deepest root is Proto-Indo-European *weyd- ("to know, see"), which led to Ancient Greek εἴδω (eídō, "I see") and then ἰδέα (idéa, "notion, pattern"). Latin borrowed this as idea, meaning a Platonic idea or archetype, and English took it from Latin. French idée is a cognate, and idol and eidolon are related.
