The word "cavalier" in literature serves a dual purpose: it designates both a courtly, chivalrous figure and an air of casual, sometimes even dismissive, nonchalance. In historical and adventure narratives it often identifies a distinguished gentleman or a military retainer—one associated with royal service or noble companionship ([1], [2], [3])—while in other contexts it characterizes a light-hearted, elegantly swaggering persona ([4], [5], [6]). Additionally, the term can appear in commercial or symbolic roles, as when it names a firm or a partner in business ([7], [8]). This multiplicity of uses allows "cavalier" to evoke images of valor and refinement as well as a certain stylish indifference throughout literary works.
