B03 investigates the emergence and development of register knowledge in Ancient Egyptian (Afro-Asiatic; c. 3200 BC - 1200 AD). Based on results from Phase I, the project now focuses on texts deriving from communicative situations characterized by social asymmetry while maintaining the research approach of the two complementary perspectives of corpus-based and single-text-based analysis. The focus is on administrative, educational, and religious texts as well as complex text-image compositions. Based on the Field-Tenor-Mode model of Systemic Functional Linguistics and insights from multimodality research, the project aims to develop a model of register variation in Ancient Egypt.
