The word "trait" in literature has been employed in an impressively multifaceted way. In some contexts it highlights distinctive qualities or characteristics inherent in individuals—whether referring to a peculiar habit in a character as noted in Verne’s work [1] or the gentle humor of Miss Keller in Helen Keller’s writings [2]—while in others it serves as an analytical term used in sociological inquiry to denote measurable differences between individuals or groups [3], [4], [5], [6]. Moreover, "trait" is sometimes encountered in its French form as "traité," indicating a formal treatise or systematic work, as seen in early discussions of coffee culture [7], [8], and in historical documents [9], [10]. In this way, the term bridges the domain of personal character with that of academic and practical treatises, illustrating its rich semantic range across genres and epochs [11], [12].
