Pronunciation

Forms

triade f (plural triades)[1]

Etymology

It is borrowed from Late Latin trias (“group of three, the Holy Trinity”), from Ancient Greek τριάς (triás), from τρεῖς (treîs, “three”).[2][3][4][5][6] The Latin word meant “the number three” and, in Christian writers, “the Holy Trinity”.[4] The sense “Chinese secret society” is borrowed from English triad (1900).[7]

Earliest recorded meaning

It is first recorded in 1562, in Ronsard's Institution pour l'adolescence, for a group of three deities.[2][4]

Semantic evolution

Bloch and Wartburg and the Grand Robert date it 1564.[8][5] Brought in as a Renaissance word for a group of three, it was soon specialized: triade harmonique in music (Brossard, 1705), a group of three persons in philosophy (Académie supplement, 1842), and the group of strophe, antistrophe and epode in the Pindaric ode (1904).[2][4] It also took technical senses in medicine and mathematics.[2][4]

The derivative triadique first described a hymn of the Greek Church whose stanzas end in praise of the Trinity (1721), then took its modern sense “relating to a triad” (1842).[4]
