In literature, the word “family” is used in a variety of ways to evoke different dimensions of human experience and social organization. Some authors use it to denote territorial or lineage-based groups, as when Satow describes leaving the domains of the Maeda family [1] or when heraldic identities are tied to noble families [2]. In other contexts, the term underscores emotional bonds and lasting separations, illustrated by the sorrowful parting in Harper’s account [3] or by the intimate concern expressed among family members in personal farewells [4]. Meanwhile, “family” can also serve as a metaphorical symbol—representing collective values, heritage, or even the societal idol—as seen in Santayana’s reflection on the familial ideal [5]. Whether referring to kinship, social status, or collective identity, literature employs the notion of family to deepen character connections and evoke broader cultural meanings.
