In literature, the term perspicacity is often employed to highlight a character’s keen insight or astuteness, whether in deciphering human nature, unraveling mysteries, or making judicious decisions. Authors use it to commend a character’s intellectual sharpness—as when a character’s perspicacity impresses or even unnerves others ([1], [2])—or to emphasize the subtle advantages of experience and refined judgment ([3], [4]). The word can denote both a natural endowment, as seen in observations of innate sensitivity or wit ([5], [6]), and a cultivated ability to discern underlying truths in social or political contexts ([7], [8]). This versatility makes perspicacity a favored term to convey the elegance of mental acuity in narrative portrayals.
