Forms

idiosyncrasie f (plural idiosyncrasies)[2][3]

Etymology

It is borrowed from Ancient Greek ἰδιοσυγκρασία (idiosunkrasía, “particular temperament”),[2][4][5][6][1] a Late Greek compound of ἴδιος (ídios, “one's own, particular”) and σύγκρασις (súnkrasis, “mixture, temperament”),[4][5][7][8] which is from κρᾶσις (krâsis, “mixing”).[4][8][9]

Earliest recorded meaning

It is first found in 1581, in Nancel's Discours très ample de la peste, as a medical term for the particular constitution of an individual.[2][7][4] Bloch and Wartburg date it 1626.[6][10]

Semantic evolution

Long a term of medicine, for an organism's own way of reacting to outside agents,[4][6] it was widened in the 19th century to a person's own temperament (1856, Baudelaire).[4][7] Under the influence of the English word idiosyncrasy, of the same origin, it took on the senses of an individual reaction to a drug, in pharmacology, and in linguistics of a speaker's personal way of organizing the rules of a language.[4]
