In literature, “swell” is a remarkably versatile term that functions as both a vivid descriptor of physical and emotional expansion and as a marker of natural dynamism. It is employed to illustrate tangible growth—whether in the gradual swelling of emotions, as when hearts fill with pride or sorrow ([1], [2]), or in physical manifestations, such as limbs or faces expanding ([3], [4]). At the same time, authors use “swell” to evoke the powerful motion of nature, capturing the rising surge of sea waves against a rock or the rolling buildup of a tide ([5], [6]). In more conversational contexts, “swell” even appears as informal praise, denoting something excellent or pleasing ([7], [8]). This diverse use underscores how the term effectively conveys both the gentle and the overwhelming in literature.
