The term swarth is employed in literature primarily as an adjective denoting a dark or dusky complexion or hue. Authors use it to vividly describe both the physical appearance of characters—as in a “swarth face” that hints at a coal-black demeanor ([1], [2], [3])—and the atmospheric qualities of nature, such as the “thick swarth of night” that envelops the landscape ([4]). Its adjectival use is sometimes even extended metaphorically or poetically to evoke a sense of bleakness or shadow, as when referring to the “harsh swarth leaves” that suggest barrenness ([5], [6]). Additionally, swarth occasionally appears in scientific and onomastic contexts, further demonstrating its versatility throughout literary and scholarly works ([7], [8]).
