The word “smooth” is employed with rich versatility in literature, functioning both as a literal descriptor of texture and a metaphor for ease or subtlety. It appears in depictions of tangible surfaces—ranging from the finely made paper that is “yellowish smooth” [1] to the “smooth as glass” water [2] and polished marbles [3]—while also lending an air of tranquility or concealed intent to characters whose expressions or speech are described as smooth, as in a “smooth face” [4] or “smooth-tongued” manner [5]. Moreover, it captures the notion of an untroubled, unobstructed progression in events and interactions, evident in passages where conflicts are “smoothed over” [6, 7] or the path of life is made “smooth” [8]. This multifaceted usage enriches narrative textures, bridging the physical and the figurative in compelling ways.
