Word Origin & Etymology

Borrowed in the late 14th century from Latin idea, from Ancient Greek ἰδέα (idéa, "form, pattern, or appearance"), which derives from the verb εἰδέναι (eidénai, "to see or know"). Originally used in English in the Platonic philosophical sense of an eternal archetype before broadening in the 17th century to mean any mental conception or thought.
