In literary works, “lighthearted” is often used to evoke a buoyant, carefree spirit that contrasts with more serious or challenging circumstances. Authors portray characters who are not only visibly cheerful—as seen when someone is described as “gay and lighthearted” [1]—but who also maintain an air of resilient optimism even amid hardship, like the Bohemian girls who never complained [2]. In some narratives, the term marks a noticeable shift in mood, such as a character becoming “quite lighthearted” after overcoming a dark influence [3], while in other texts it underlines an inherent playfulness or a subtle, enduring sense of joy [4, 5]. This multifaceted usage enriches the narrative by capturing moments of levity, self-assurance, and the contagious nature of a jubilant outlook.
