The term "quavering" is often used in literary works to evoke a sense of vulnerability, uncertainty, and emotional fragility. It describes voices and sounds that falter, tremble, or waver, thereby enriching character portrayal and setting the mood. For instance, a quavering voice can reveal a character’s fear or hesitance, as when a timid inquiry is made [1] or when a sorrowful, unstable tone underlies an outburst of emotion [2]. Authors also extend its use to capture fluctuating ambient sounds that mirror inner turmoil, further enhancing the narrative’s tension and depth [3, 4]. Such usage underscores the power of the word to convey delicate, almost imperceptible shifts in mood and character.
