In literature, fluent denotes a smooth, effortless quality in language—whether spoken or written—that conveys ease and mastery. Authors use the term to highlight the natural flow of speech, as when a prayer is recited with an unforced cadence [1] or a conversation moves along with precise ease [2, 3]. It is also employed to praise a clear and coherent literary style that is free from obscurity and affectation [4], and to indicate a graceful command over linguistic expression seen in both oratory and written prose [5, 6]. Across varied contexts, fluent serves as an affirmation of articulate, rhythmic communication that engages the listener or reader without distraction [7, 8, 9].
