The term "enmity" is employed in literature to evoke profound, often irreversible hostility, whether between individuals, groups, or even abstract forces. It appears not only as a marker of personal vendettas or familial strife—as in tragic encounters and feuds depicted through dramatic dialogue ([1], [2])—but also as a symbol of broader social or political opposition, capturing conflicts rooted in history or ideology ([3], [4], [5]). In some works, it even contrasts with friendship and love, highlighting the inherent duality in human relationships and the perpetual tension that drives narratives ([6], [7], [8]). Thus, its usage across different genres—from epic poetry and historical accounts to dramatic plays and philosophical treatises—reveals its versatility in expressing the intense, sometimes fated animosities that shape both personal destinies and the course of nations.
