In literature, the adjective "relentless" is often employed to evoke a sense of unyielding force or an unstoppable, pervasive quality in both natural and human-powered phenomena. It can describe literal elements like an unremitting sea or harsh weather, as when hope is depicted sinking "like spent swimmers in a relentless sea" ([1]), or metaphorically, when fate or antagonistic forces pursue with unwavering determination, as seen in references to a "relentless foe" ([2]). Authors use the term to intensify conflict or underscore the inevitability of an action—whether it’s the grim defiance in the face of an enemy ([3]) or the soul-stirring logic driving an individual's self-realization ([4]). In these ways, "relentless" becomes a powerful literary device, imbuing narratives with a persistent, almost elemental energy that heightens the stakes and deepens the emotional resonance of the text ([5], [6]).
