Book excerpt: This volume is intended as a celebration of Kristin Davidse’s work and its impact within the broad traditions of cognitive, functional and usage-based grammars. Reflecting this wide functionalist lens, the contributions develop ideas central to Neo-Firthian theories of grammar (in particular, Semiotic Grammar and SFL), the Prague School, Functional Discourse Grammar (FDG), and broader cognitive-functional (e.g. Construction Grammar) and usage-based approaches (e.g. Entrenchment-and-Conventionalization theory, corpus-based sociolinguistics). The range of topics addressed makes the volume particularly relevant to linguists investigating information structure, construction grammar, functional discourse grammar, spatial deixis, pronoun and case systems, and/or the semantics of verbal constructions.
