This study examines gendered linguistic practices in Post-Classical Greek (31 BC–600 AD) by analyzing bidirectional texts, i.e. written exchanges that reflect an interaction between sender and recipient, including documentary letters, petitions and fictional letters. Unlike previous research, this study focuses on female language by integrating literary and documentary texts to provide a more comprehensive understanding of gendered linguistic practices. Through a historical sociopragmatic approach, the research explores how gender performance influences discourse structures, speech acts, and politeness strategies. The corpus categorizes bidirectional texts by different social variables and communicative purposes. A multi-layered analysis investigates linguistic variation at macro (sociocultural context), meso (generic and discourse structures), and micro (politeness strategies) levels. Quantitative and qualitative methods will assess whether women’s linguistic choices reflected and performed specific social roles, power dynamics, and interpersonal relationships. Additionally, the study examines male-controlled portrayals of female speech in fictional letters to evaluate gender performance in literary representations. By bridging the gap between literary and documentary evidence, this project contributes to gender studies and historical sociopragmatics, offering new insights into the role of language in performing and negotiating gender identity in ancient Egypt.
