In literature, discourtesy is often portrayed as a breach of expected social norms, serving as a marker for both minor transgressions and deeper character flaws. Authors employ the term to highlight moments when personal or social boundaries are transgressed, sometimes invoking a simple lapse in etiquette and other times signaling an intentional insult or moral failing. In one narrative, a character’s blatant discourtesy causes hurt and alienation among peers ([1]), while in a political drama, it marks an act of deliberate defiance toward authority ([2]). The word is also used in a reflective or apologetic tone, as seen when a writer expresses regret for any slight caused ([3], [4]), and it appears even in contexts meant to emphasize the inevitability of changing customs and manners ([5]). Across these varied contexts—from formal settings to everyday interactions—the term encapsulates the tension between societal expectations and individual behavior.
