Book excerpt: This volume brings together seven eminently original attempts to answer a sorely neglected question: What are adjectives? Although the positioning of adjectives as well as aspects of their semantics have been investigated in depth, their actual status as a lexical category has generally been treated superficially in the linguistic literature. In this volume, the different approaches to the categorial identity of adjectives put forward include their position in the inventory of lexical categories, the elusive noun-adjective link, the functional entourage of adjectives and their relational character, the role of concord and possession – and so on. The contributors bring different viewpoints as well as a variety of language data into the discussion, from Chinese to Indo-European, and on to Niger-Congo languages.
