Did you know?

Celerity hasn’t acted with much expressive celerity since its entry into English in the 1400s: it refers now as it did centuries ago to swiftness of motion or action. Its source (by way of Middle French) is the Latin adjective celer (“swift” or “speedy”), a word from which we also get accelerate, and there is some evidence of a trace of equine celerity in its deeper history: celer may go back to an Indo-European word that is the ultimate source of a Greek word meaning “swift horse” or “charger.” We know what you're thinking: whoa.
