The word "grunt" in literature often functions as a succinct vocal shorthand that conveys a range of emotions and attitudes—from terse acknowledgment or disapproval to expressions of exertion and animalistic behavior. Authors use it to impart a very human quality to minimal speech, as in a reluctant response or simple assent [1][2], while in other contexts it evokes the raw, earthy sounds of nature or even serves as a metaphorical marker of a character’s mood and social demeanor [3][4][5]. In some works, a grunt punctuates a scene with understated humor or serves as an entirely non-verbal means of communication that enhances realism, as seen when it signals fatigue, surprise, or simple contempt [6][7][8]. This versatility makes the grunt a valuable literary device, rich in expressive potential and capable of deepening a narrative’s atmosphere with just one sound [9][10].
