The quality of being able to speak or write a language easily, smoothly, and rapidly.

Focuses on natural flow and lack of hesitation rather than absolute grammatical perfection.

The story behind the word. Traced back to Latin 'fluentia' meaning 'a flowing'. Originally used to describe the smooth current of rivers, by the 16th century English speakers applied it metaphorically to speech that flows like water.
