This chapter explores the culturally specific semiotics of ta’ārof, the ritualized system of politeness that structures Iranian social interactions, as portrayed in Asghar Farhadi’s critically acclaimed film About Elly. Grounded in the Semio-Cultural Conceptualizations Framework, the chapter examines how ta’ārof functions through a range of speech acts that both maintain and challenge social cohesion. These include offers and refusals that perform politeness through mutual deference; apologies and expressions of regret that serve to repair social harmony; indirect criticism and accusations that preserve face while conveying disapproval; gratitude and appreciation that reaffirm bonds of respect; requests and commands that navigate the tension between urgency and social decorum; and explanations and justifications that uphold individual accountability within collective norms. By analyzing these communicative practices in both verbal and nonverbal forms, the chapter illustrates how ta’ārof mediates status, morality, and group belonging. Rather than treating ta’ārof as mere etiquette, the study reveals its role as a complex semiotic system that reflects, reproduces, and sometimes resists the sociocultural values of Iranian modernity.
