Did you know?
Flexuous is a synonym of curvy. It is typically used in botany to describe plant stems that aren't rigid. But don't let that tendency deflect you from occasionally employing this ultimately quite flexible word. Stemming straight from Latin flectere, meaning "to bend," it can also mean "undulating" or "fluid." It might, for example, be used of writing or music, or of something or someone that moves with a fluid sort of grace.
