Pronunciation

Forms

idéal (feminine idéale, masculine plural idéaux, feminine plural idéales)[1] As a noun it is masculine, with the plurals idéaux and idéals.[2][3]

Etymology

It is borrowed from Medieval Latin ideālis (“relating to the idea”), derived from Latin idea, itself from Ancient Greek ἰδέα (idéa, “idea”).[4][2][1] Bloch and Wartburg call the Latin adjective Late Latin and say it was borrowed to serve as an adjective for certain senses of idée.[5]

The noun is at once a borrowing (1746) of the philosophers' German Ideal, which itself came from the Medieval Latin adjective, and the adjective used as a noun.[2][4] The TLFi notes that the German word was spread by the works of Kant and Lessing.[4]

Earliest recorded meaning

The TLFi's first record is from 1551, in Du Parc Champenois's translation of L. Hébreu's Philosophie d'amour: formalité ideale, of what exists only in the mind or imagination.[4][2] Bloch and Wartburg, the GLLF and Littré give Desportes, 1578: Leur forme idéale.[5][6][7]

Semantic evolution

The adjective first meant “existing only in the mind, not perceived by the senses”.[2][4] It came to mean “uniting every perfection the mind can conceive” (Buffon, 1758), whence le beau idéal in art (Falconet, 1760), opposed to natural beauty.[2][6] It also entered economics (1766, monnaie idéale) and later mathematics (early 20th century, nombres idéaux).[2] In everyday language it meant “chimerical” (1762), and since 1812 it has also meant “having every quality one could wish”, a sense now common in advertising.[2][6]

The noun first named the set of the most fitting abstract representations of a thing (Batteux, 1746), then the inner model guiding an artist (Diderot, 1765), and the perfect type one imagines (Senancour, 1799).[4][2] Used absolutely (Hugo, 1831) it is the set of aesthetic, moral or intellectual values opposed to material interests, a key word of Romantic aesthetics; from 1836 (Stendhal) it is what gives perfect satisfaction, and familiarly (before 1902, Zola) l'idéal, ce serait de… “the best thing would be”.[2][4] Mathematics uses it for a kind of subring (1903).[2]
