Root Explanation

Idiosyncrasy is formed from "idio-" (from Greek "idios", meaning one's own or private) and "synkrasis" (from Greek, meaning mixture or blending). The word refers to a personal peculiarity or characteristic that is unique to an individual, thus highlighting their own unique mixture of traits.

Memory Tip

Think of 'one's own' ('idio-') characteristics being 'mixed' ('synkrasis') together — that's what idiosyncrasy means, a unique blend of personal traits.
