Review of Sommerer & Smirnova (2020): Nodes and Networks in Diachronic Construction Grammar.

The book "Nodes and Networks in Diachronic Construction Grammar" edited by Lotte Sommerer and Elena Smirnova is a collection of papers that explore language change within the framework of Diachronic Construction Grammar (DCxG). The book is divided into three parts: "The Nodes: Creation, Change and Loss," "The Links: Vertical and Horizontal Relations," and "Beyond Existing Models." The papers cover topics such as the emergence and loss of linguistic nodes, constructional competition, and the reconfiguration of constructional networks. The book offers valuable insights into how to model constructional networks and raises important questions for future research. However, it is primarily focused on English constructions and could benefit from more diverse linguistic data. [Extracted from the article]
