The present study tackles impoliteness strategy in Tennessee Williams' A Streetcar Named Desire. The major objectives of this study are to determine the impoliteness strategies used by the characters and figure out their reaction when facing an offensive situation. Additionally, it aims to state if there is a distinction between male and female characters in performing impoliteness. Relying on a mixed methods approach, this study adopts Culpeper's (2005) model of impoliteness strategies, Bousfield's (2008) model of responses to impoliteness, and Culpeper's (2011) model of types of impoliteness. The findings of this study show that positive impoliteness is the most dominant strategy used, with the percentage of 31.1%. Moreover, Blanche performs impoliteness strategies more than the other characters, with the percentage of 41.83%. All options of responses to impoliteness are found in the play. Furthermore, the analysis reveals that power, gender, emotions, social distance, and culture lead the characters to utilize offensive language.
