Forms

ῐ̓δέᾱ (idéā) f (genitive ῐ̓δέᾱς); first declension[1]

Etymology

It is a verbal abstract from ἰδεῖν (ideîn, “to see”), formed like ἀλέα (aléā, “warmth of the sun”).[2][3] It goes back to the Indo-European root Proto-Indo-European *weyd- (“to see”) and is closely related to εἶδος (eîdos).[2][1]

Earliest recorded meaning

Its first recorded uses are in the 6th century BC: Theognis has the plural for outward appearances that deceive the mind, and Pindar uses it for a person's beauty of form.[4][5][6]

Semantic evolution

Herodotus used it for appearance and for kind or sort, and Thucydides for the nature of an epidemic or a war and for a way of attacking a city.[5][7] Isocrates and Aristotle used it for literary form, and Democritus is reported to have called his atoms “indivisible forms”.[7][5] In Plato it is the idea of something, and above all the Forms, the ideal patterns opposed to particular things, and Aristotle discusses them under this name.[7][2]

In the New Testament it is outward appearance: the angel's “appearance was like lightning” (Matthew 28:3).[5][8] Latin borrowed it as idea, and through Latin it reached Russian and other languages.[1] Modern Greek ιδέα kept the ancient senses as a learned word; its sense “idea, notion” is a semantic loan from French idée and German Idee.[9]
