In literature, "enigmatic" is often used to create an air of mystery that both intrigues and unsettles the reader. Authors employ the word to describe characters with ambiguous expressions—whether it's an enigmatic smile that hints at hidden depths or secretive glances laden with meaning ([1], [2], [3])—or to characterize situations and objects that resist straightforward explanation, such as puzzling notes or mysterious architectural visions ([4], [5]). The term frequently imbues a subject with dual qualities of allure and inscrutability, as seen in characters whose eyes or expressions remain both fascinating and unfathomable ([6], [7]). In this way, "enigmatic" serves as a literary tool for suggesting complexity and the promise of unseen layers beneath the surface ([8], [9], [10]).
