Book excerpt: This volume explores changing norms and conventions in the English language, as displayed in a broad range of historical data from more than five centuries. The contributions discuss the interplay of sociocultural conditions, specific discourse traditions and structural aspects of language, paying special attention to the communities where norms and conventions are displayed and shaped in verbal interaction. The volume is enriched by systematic terminological clarifications, interdisciplinary approaches and the introduction of new methods like network analysis and advanced analytical tools and forms of visualisation into the diachronic investigation of historical texts.
