In literature, asperity is frequently employed to convey a sharp, biting quality in both tone and description. Writers use it to characterize speech that is abrupt, irritable, or laden with underlying hostility, as when a character retorts with a brisk, unyielding edge [1, 2, 3]. It also appears in depictions of physical texture, suggesting roughness or unevenness, as when every asperity of the soil is illuminated by light [4]. Through such varied applications—from the sharpness of a diplomat's rebuke [5, 6] to the physical jaggedness of a landscape—the term enriches narrative textures by evoking a sense of uncompromising severity and emotional intensity [7, 8, 9].
