An idiosyncrasy is an unusual feature of a person (though there are also other uses, see below). It also means odd habit. The term is often used to express eccentricity or peculiarity.[1][2] A synonym may be "quirk".


The term "idiosyncrasy" originates from Greek ἰδιοσυνκρασία idiosynkrasía, "a peculiar temperament, habit of body" (from ἴδιος idios, "one's own", σύν syn, "with" and κρᾶσις krasis, "government") or literally "self-ruled".
