Grammaticalization research has increasingly highlighted the notion of constructions in the last decade. In the wake of this heightened interest, efforts have been made in grammaticalization research to more precisely articulate the largely pretheoretical notion of construction in the theoretical framework of construction grammar. As such, grammaticalization research increasingly interacts and converges with the emerging field of diachronic construction grammar. This volume brings together articles that are situated at the intersection of grammaticalization research and diachronic construction grammar. All articles share an interest in integrating insights from grammaticalization research and construction grammar in order to advance our understanding of empirical cases of grammaticalization. Constructions at various levels of abstractness are investigated, both in well-documented languages, such as Ancient Greek, Latin, Spanish, German, Norwegian and English, and in less-described languages, such as Manchu and Mongolian.
