definition of fluency
Then you have fluency. Fluency is a type of smoothness used most often when talking about language. You could study a language â like Spanish â for years and not really gain fluency. To have fluency â in other words, to be fluent â takes a lot of practice. Fluency can't be achieved overnight. That kind of expert use of language takes time, and it helps if you get a chance to visit a country where they speak the language you're learning.
