Etymology

Origin of celerity

First recorded in 1480–90; earlier celerite, from Middle French, from Latin celeritās, equivalent to celer “swift” + -itās -ity


Explanation

While it looks a lot like "celery," celerity means something that vegetables are not — fast moving. Gossip often travels with celerity, as do children trying to get to a big plate of cookies. When you see the word celerity, think accelerate, like a car when you step on the gas. Both words share the Latin root celer which means "swift." You may want to study for exams with celerity, but using a slower, more methodical approach will often yield better results.
