Did you know?
Eccentric was originally a technical term at home in the fields of geometry and astronomy. It comes from a Latin word meaning “not having the earth at its center,” and ultimately has its root in a Greek word with various meanings including “stationary point of a pair of compasses” and “midpoint of a circle or sphere.” But its figurative use is long-established too: as far back as the 17th century the word was used to describe people and things that deviate from what is conventional, usual, or accepted.
