Intersectionality is a theoretical and practical framework that has its roots in critical race studies and feminist studies and is now widely used in various fields, including drama analysis. This theory reminds us that individuals' identities are not constructed from a single identity marker but rather from a combination of various factors such as gender, race, and social class. The interaction and mutual influence of these factors can sometimes lead to the formation of intersectional discriminations in an unequal society, which is a unique experience. Intersectionality, as an approach in drama analysis, provides a lens to see the representation of characters with multiple identities amidst these intertwined discriminations. The present study, using a descriptive-analytical method, seeks to answer the question of how the concepts of identity and intersectional discrimination are addressed in the characterization of the play "Sweat." The findings of this research reveal that Lynn Nottage, in the play "Sweat," has tried to portray multiple identities of workers in a declining society and the intertwined discriminations associated with these identities through intersectional characterization and highlighting the interaction and mutual influence of various types of discrimination, such as gender, racial, and economic discrimination. She has also reflected on the role of power, both within and across domains of power, in shaping these discriminations. Determining the social contexts with measures such as mentioning documented news and events that have made it possible to relate the presentation of social inequality in a specific society is another feature of this complex and profound play. Inequality that is not caused by a single factor but is shaped by multiple factors. The necessity of social justice is also highlighted by showing the consequences of neglecting marginalized characters, particularly in their interactions with other characters such as Oscar and the fate of Stan. These are all central themes that are also addressed in intersectionality theory.
