Etymology

fluency = flu<flow> + ency<noun suffix>

  • flu (from Latin fluere, meaning "to flow")
  • ency (a noun-forming suffix indicating a state or quality, derived from Latin -entia)

Etymology Origin:
The word "fluency" traces back to the Latin fluentia, meaning "a flowing." The root flu- reflects the concept of smooth, uninterrupted movement, which evolved metaphorically to describe effortless speech or skill in language. The suffix -ency transforms the adjective "fluent" into a noun denoting the quality of flowing ease. This logical progression—from literal flow to linguistic mastery—highlights how physical metaphors shape abstract concepts in language.
