In literature, “nod” emerges as a versatile gesture conveying much more than a mere tilt of the head. Writers employ the nod to communicate silent assent or dissent, as well as to establish moods ranging from respectful deference to subtle irony. It often marks a turning point in dialogue—a brief, wordless confirmation that carries emotional weight ([1], [2]), or a dismissive gesture that underscores social and political hierarchies ([3], [4]). Moreover, in epic narratives it is imbued with mythic significance, representing divine sanction or imperial command that reverberates through the story ([5], [6]). Even in more intimate or humorous moments, the nod encapsulates unspoken understanding or gentle rebuke, proving that this small movement can speak volumes in the hands of a skilled author ([7], [8]).
