The term "discourteous" in literature is often used to highlight breaches of etiquette and civility that carry social or personal consequences. Authors employ it to mark moments when characters either commit or react to lapses in courteous behavior, whether through overt insults or subtle slights. For instance, it is used in contexts where a minor transgression almost leads to dramatic outcomes—a challenge to a duel over a single discourteous act ([1])—or where characters carefully navigate social interactions to avoid being labeled as rude ([2], [3]). In other works, the word underscores the tension between personal feelings and societal expectations, such as when a character apologizes for discourteous silence or conduct ([4], [5]), or when it critiques the behavior of those in power ([6], [7]). Across these narratives, "discourteous" functions as a descriptor that not only defines a character’s actions but also reflects the broader cultural importance of civility.
