Writers deploy the word “endearment” to convey affection, familiarity, and sometimes even social nuance. In literature, it frequently designates tender appellations between loved ones, as when a wife addresses her husband with unwavering warmth [1] or when a parent naturally employs a pet name with profound intimacy [2]. At the same time, endearment can serve as a subtle marker of cultural or hierarchical distinctions—ranging from the affectionate diminutive in dialects to terms rooted in ancient language, thereby linking characters to traditions or social orders [3][4][5]. Authors also juxtapose gentle expressions of endearment against harsher tones, emphasizing the complexity of human interaction, whether in moments of tenderness amid conflict or during brief, affectionate interludes that reveal character depth [6][7]. In this way, the term transcends mere fondness, becoming a literary tool that captures the multifaceted interplay of emotion and societal relations [8][9].
