Liina Pylkkänen's book *Introducing Arguments* explores the linguistic mechanisms that allow non-core arguments, which are not introduced by verbal roots, to be integrated into argument structures. The book, based on her Ph.D. dissertation at MIT, discusses complex predicates and their integration in human language, with a detailed focus on Japanese constructions. Pylkkänen argues that these non-core arguments are introduced by seven functional heads, including Voice, which introduces external arguments. She further suggests that cross-linguistic variation is due to parametric factors such as the type of functional heads selected and how they are bundled into syntactic heads. The book examines various constructions, including double object constructions, benefactives, possessor datives, adversity passives, and causatives. Pylkkänen proposes that applicative constructions can be divided into high and low types, with high applicatives denoting a relation between an event and an individual, and low applicatives denoting a transfer-of-possession relation. She also discusses causative constructions, proposing that they involve a causative head (Cause) that combines with non-causative predicates to introduce a causing event. Cross-linguistic variation in causatives is attributed to two parameters: Voice-bundling, which determines whether Voice and Cause are separate heads, and selection, which specifies the type of complement selected by the causative head. Pylkkänen's work is influential in linguistics, particularly in the areas of argument structures, complex predicates, and verbal semantics. Her detailed analysis and extensive data from various languages make her proposal a significant contribution to the field. The book provides a unified framework for understanding complex predicates and leaves room for further research and theoretical development.Liina Pylkkänen's book *Introducing Arguments* explores the linguistic mechanisms that allow non-core arguments, which are not introduced by verbal roots, to be integrated into argument structures.
