Idiosyncrasy, from Ancient Greek ἰδιοσυγκρασία, idiosynkrasía, "a peculiar temperament", "habit of body" is defined as an individualizing quality or characteristic of a person or group, and is often used to express eccentricity or peculiarity. The term can also be applied to symbols. Idiosyncratic symbols mean one thing for a particular person, as a blade could mean war, but to someone else, it could symbolize a surgery.
