Writers often use "vivacious" to infuse their descriptions with a sense of lively, spirited energy that enlivens characters and settings alike. In many literary depictions, the term characterizes a person’s animated charm—be it the mysteriously elegant heroine whose presence is unforgettable [1] or the quick-tempered, mature-appearing individual with an unmistakable dash of French verve [2]. It is equally adept at capturing the dynamic atmosphere of social interactions and narrative style, as seen in accounts of unrestrained, engaging table-talk [3] or the distinctly compelling style of narrative delivery [4]. This versatility not only brings characters to life but also imbues the overall tone with an energetic, almost palpable quality [5, 6].
