The word “doctor” in literature is used in a variety of ways that underscore its multiple roles—from the literal, as a healer or medical professional, to a title that conveys authority or even irony. In many works, a doctor is portrayed as a figure of both expertise and vulnerability; for example, Chekhov’s dishevelled doctor climbing the stairs suggests both his human frailty and occupational burden ([1]), while Dickens’ references to doctors, whether in the context of military duty or civic responsibility ([2], [3]), emphasize their variegated social roles. Authors also employ the term to evoke professional learnedness or to underline the dramatic tension in a scene, as seen when a doctor’s intervention becomes central in narratives like those of Dickens and Tolstoy ([4], [5]). In other instances, “doctor” is used with a touch of humor or irony—whether to soften a rebuke or capture a moment of human absurdity, as in the witty dismissal in Twain’s narrative ([6]). Overall, literature uses the term “doctor” not just to denote a specific profession but also as a versatile symbol of knowledge, authority, and the nuances of human condition.
