Word Root of fluid
The Latin word fluere, meaning “to flow,” gives us the root flu. Words from the Latin fluere have something to do with flowing. A fluid is a substance that flows and is usually a liquid. When someone is fluent in a language the words flow out of her or him. Anything superfluous, or extra, has flowed forth beyond what is necessary.
