Literary works employ the term mood in a variety of nuanced ways. It can depict a character’s emotional state or frame a narrative’s tone—as when a character is described as being “in a happy mood” or, conversely, brooding over the past [1, 2]. At times, mood not only reflects transient feelings, such as festive or melancholic states [3, 4], but also serves to shape the atmosphere of a setting or overall work [5, 6]. Meanwhile, in discussions of language itself, the word takes on a technical role, denoting grammatical forms like the indicative, subjunctive, and imperative [7, 8]. This multiplicity of uses shows how mood functions both as an indicator of inner experiences and as a tool in the writer’s craft to influence readers’ perceptions.
