The word "mumble" in literature often conveys a sense of indistinctness and emotional or social uncertainty. Authors use it to depict characters whose speech is hesitant or deliberately obscured, suggesting everything from subdued contentment, as when a soft murmur hints at reassurance [1], to deep distress or embarrassment when a character erupts in tears while barely managing to explain themselves [2]. In some narratives, the act of mumbling underscores irony or subtle humor—as seen when it is repeated mockingly by a clergyman [3] or employed to add a layer of casual nonchalance in social interactions [4]—while in others, it evinces spiritual devotion or resigned monotony, whether in the lament of praise to God [5] or in the uncomprehending mutterings of a disoriented soul [6].
