idea

idea: [16] Etymologically, an idea is the ‘look’ of something – it comes ultimately from the same source as produced the Greek verb ídein ‘see’. Greek idéā itself was used by Plato in the specialized sense ‘archetypal form of something’, which survives in the derived adjective ideal [17], but as far as the modern English noun is concerned, its sense ‘notion, mental conception’ developed (in Greek) via ‘look, appearance’, ‘image’, and ‘mental image’. Ideology [18] is a derivative, coined originally in French at the end of the 18th century.
=> ideology, idol
