Authors employ "squeak" as a versatile onomatopoeic device that evokes diverse soundscapes—from the quiet, reassuring proof of life in an object ([1]) to the high-pitched outburst of a character's failing voice ([2],[3]). Its use traverses the human and animal realms, capturing the subtle protest of a rat behind a wall ([4]) or the whimsical charm of a mouse peeping out of its hole ([5]). At times, the word enhances a setting's atmosphere by mimicking mechanical sounds—as in the creak of a swing door ([6],[7]) or the sudden, almost unexpected noise that punctuates a narrative ([8],[9]). This breadth of usage highlights how "squeak" is a succinct way to invoke both the mundane and the dramatic in literature.
