In literature, "reproachful" serves as a versatile adjective that not only delineates a speaker's tone but also vividly portrays a character's internal state and relational dynamics. Authors employ it to underscore disapproval or regret—often conveyed through a glance, remark, or manner of speech. For instance, a reproachful tone may emerge in a character's admonishing question or a self-directed sense of contrition, as seen in narrative moments where a character’s eyes or voice communicate silent censure or self-reproach ([1], [2]). At other times, it heightens dramatic tension by emphasizing a character’s moral indignation or disappointment, such as when sharply worded accusations are delivered in a reproachful accent or look ([3], [4]). This dynamic usage imbues dialogues and interactions with an emotional depth that reveals conflicts, social expectations, and personal remorse across a broad spectrum of literary works ([5], [6]).
