Definition: a peculiar way of behaving or thinking that is particular to an individual or group

Synonyms: characteristic, peculiarity, quirk, eccentricity

Antonyms: commonality

Tips: A person's idiosyncrasy is a peculiar quirk or habit that makes someone unique. For a memory trick, think of idiosyncrasy as a way of denoting the actions of someone who is out of sync with what is "normal," or a little "crasy" (crazy). Notice both "sync" and "crasy" (crazy) in the word idiosyncrasy. Eccentricity is a synonym for idiosyncrasy. Eccentric (odd, peculiar, unique) is usually an adjective used to describe someone with idiosyncrasies (odd mannerisms) rather than saying the person is idiosyncratic.

Usage Examples:

He had some odd idiosyncrasies, like asking people to take their shoes off before entering his office. (peculiarities, quirks)

His obsession with velvet Elvis paintings was just one of his many idiosyncrasies. (eccentricities, quirks)

One of the idiosyncrasies of this printer is that you can't stop it once it has started to print. (unusual feature)

I am not sure why he always taps his head when he thinks; itís just an idiosyncrasy. (peculiar mannerism)
