The term "muttered" is frequently employed in literature to indicate speech that is subdued, reflective, or laced with emotion. Authors often use it to reveal a character’s inner thoughts or to express sentiments that are too delicate or charged to be spoken aloud clearly, as when a character quietly reveals a hidden fear or resignation [1] or laments a personal circumstance with understatement [2]. Occasionally, it also serves to punctuate moments of contempt or irony, letting the reader glimpse a character’s true, perhaps unsentimental, feelings [3]. In dialogues that brim with subtleties and unspoken layers, “muttered” enriches the narrative by marking the transition between exterior civility and inner turmoil [4], [5].
