Discourse grammar

After nearly a decade since the recognition of the importance of theticals, traditionally referred to as parenthetical constructions (see Kaltenböck et al. 2011; Heine et al. 2013), there has been a flurry of research on these linguistic elements across various languages, including but not limited to Romance languages (Schneider, 2007), Chinese (Long et al., 2019), Persian (Kazemian & Amouzadeh, 2019), and Arabic (Haddad, 2020). However, it appears that theticals still remain relatively understudied and warrant more comprehensive and fresh examination. This lack of interest in studying theticals, particularly those inherent in interaction, has prompted Bernd Heine to undertake writing a new book, “The Grammar of Interactives”, dedicated to these items and analyzing them as a distinct level called interactive grammar (IG) which works alongside sentence grammar (SG) to facilitate successful communication. The book is structured in a cohesive and organized manner, consisting of an introduction, six main chapters, and a conclusion, totaling eight chapters in all. This structure properly presents the book's content by establishing the context and scope in the introduction, delving into the subject matter in the core chapters each exploring a specific theme related to the overall subject, and providing a sense of closure and reflection in the conclusion.
