This book presents a controlled evaluation of three widely practised syntactic theories on the basis of the extremely complex agreement system of Archi, an endangered Nakh-Daghestanian language. Even straightforward agreement examples are puzzling for syntacticians because agreement involves both redundancy and arbitrariness. Agreement is a significant source of syntactic complexity, exacerbated by the great diversity of its morphological expression. Imagine how the discipline of linguistics would be if expert practitioners of different theories met in a collaborative setting to tackle such challenging agreement data - to test the limits of their models and examine how the predictions of their theories differ given the same linguistic facts. Following an overview of the essentials of Archi grammar and an introduction to the remarkable agreement phenomena found in this language, three distinct accounts of the Archi data examine the tractability and predictive power of major syntactic theories: Head-driven Phrase Structure Grammar, Lexical Functional Grammar, and Minimalism. The final chapter compares the problems encountered and the solutions proposed in the different syntactic analyses and outlines the implications of the challenges that the Archi agreement system poses for linguistic theory.

This is the first book to present Canonical Typology, a framework for comparing constructions and categories across languages. The canonical method takes the criteria used to define particular categories or phenomena (eg negation, finiteness, possession) to create a multidimensional space in which language-specific instances can be placed. In this way, the issue of fit becomes a matter of greater or lesser proximity to a canonical ideal. Drawing on the expertise of world class scholars in the field, the book addresses the issue of cross-linguistic comparability, illustrates the range of areas - from morphosyntactic features to reported speech - to which linguists are currently applying this methodology, and explores to what degree the approach succeeds in discovering the elusive canon of linguistic phenomena.

This book explores unusual patterns of agreement, one of the most intriguing and theoretically challenging aspects of human language. Agreement is typically thought to reflect a structural relationship between a verb and its arguments within the clause, and all major theories of agreement have been developed with the centrality of this relationship in mind. But beyond the verb, items belonging to practically every other part of speech have been found to function as agreement targets, including adpositions, adverbs, converbs, nouns, pronouns, complementizers, and other conjunctions. Data on these targets provide rich insights into the structural domains in which agreement operates, demonstrating that unusual targets can be associated with unexpected domains that are independent of the agreement domain of the verb. Following an introduction to the typology of unusual targets and unexpected domains across the world's languages, the chapters in this volume provide detailed treatments of a wide range of rare and complex agreement phenomena in seven languages, belonging to five different language families of Eurasia and the Pacific. The contributions are all based on novel data collected by the authors, which detail the syntactic, semantic, and pragmatic properties of agreement on non-verbal targets within the clause.
