Impoliteness plays a crucial role in shaping social relationships, particularly within marginalized families where verbal aggression is embedded in everyday survival strategies. This chapter examines impoliteness in Saeed Roustaei’s Abad o Yek Ruz (Life and a Day), focusing on how economic hardship, gender hierarchy, and cultural expectations drive verbal confrontations. Utilizing Culpeper’s impoliteness taxonomy and Sharifian’s analytical framework of cultural conceptualizations, the study identifies and categorizes impolite interactions into six thematic areas: emotional frustration, gender expectations, generational conflict, power struggles, economic hardship, and personal attacks. Findings indicate that impoliteness in such context functions not only as an expression of frustration but also as a means of maintaining control, enforcing norms, and negotiating familial dynamics. While certain cultural schemas institutionalize impoliteness—such as gender-based verbal dominance—others provoke impolite responses when violated, illustrating how verbal aggression is deeply rooted in Persian discourse. This study provides a culturally grounded perspective on impoliteness, arguing that in marginalized families, verbal aggression fulfills practical, social, and psychological roles rather than merely disrupting social harmony.
