Full origin of idiosyncrasy →Frequently Asked Questions
What is the difference between an idiosyncrasy and a quirk?
They overlap almost completely, but quirk is shorter, warmer and more everyday, while idiosyncrasy is formal and suggests a settled trait rather than a one-off oddity.
How do you spell and pronounce idiosyncrasy?
It ends in -crasy, not -cracy, because it comes from krasis meaning mixture rather than kratos meaning power. Say id-ee-oh-SING-kruh-see, with the stress on the third syllable.
Is calling someone idiosyncratic a compliment?
It is usually mild and affectionate, suggesting individuality rather than fault. It can be a polite way of noting that someone is difficult, so tone and context matter.
