Etymology
It is borrowed from Ancient Greek ἰδέα (idéa, “form, notion, pattern”).[2][1][3]
Earliest recorded meaning
Cicero still writes the Greek word in Greek letters, though many manuscripts have it in Latin, and Seneca the Younger uses it as a Latin word in his Letters.[4][5][6] Köbler dates Seneca 4 BC–65 AD.[3]
Semantic evolution
In Classical Latin it was a term of Platonic philosophy, an idea or eternal archetype of things.[2][5] Vitruvius, Apuleius and Macrobius also use it, often in Greek letters.[6]
Medieval Latin used it of the archetype or form, of what conforms to the idea, and of something perfect or ideal, as when Abelard is said to posit ideas in emulation of Plato.[7][8] English idea is recorded in the late 14th century, first of an archetype or the concept of a thing in the mind of God.[9]
