Literary notes about Expletive (AI summary)
In literature the term "expletive" serves a dual purpose. On one hand, it appears as a burst of raw emotion—a curse or sharp interjection that reveals a character’s inner turmoil or spontaneous reaction, as when a character expresses deep disappointment or surprise [1][2][3]. On the other hand, it functions as a stylistic or grammatical filler that adds rhythm and emphasis without necessarily conveying profanity, operating more like a neutral linguistic placeholder in the narrative [4][5][6]. Authors use this versatile device both to animate character dialogue and to ornament sentence structure, enhancing the overall texture of their work—from a fleeting sigh that punctuates silence [7] to a forceful outcry that colors an entire scene.
