Word Origin
- idiosyncracy
- idiosyncracy: [17] Greek idios meant ‘of a particular person, personal, private, own’. Among the words it has contributed to English are idiom [16] (etymologically ‘one’s own particular way of speaking’), idiot, and idiosyncracy. This was a compound formed in Greek with súgkrāsis, itself a compound noun made up of sún ‘together’ and krāsis ‘mixture’ (a relative of English crater). Súgkrāsis originally meant literally ‘mixture’, but it was later used metaphorically for ‘mixture of personal characteristics, temperament’, and so idiosúgkrāsis was ‘one’s own particular mix of traits’.=> idiom, idiot
