Etymology

Origin of oddity

First recorded in 1705–15; odd + -ity

Explanation

An oddity is anything strange or unusual. Wearing ear muffs during a heat wave would be considered an oddity, because most people wouldn't do that. Anything odd is weird, strange, unusual, or bizarre. Oddities are things like that. Calling good friends "sir" would be an oddity, since that word is usually used in formal situations. Oddities can also be objects, especially unusual objects or souvenirs someone might collect.
