Morphology is particularly challenging, because it is pervaded by irregularity and idiosyncrasy. This book is a study of word structure using a specific theoretical framework known as 'Network Morphology'. It describes the systems of rules which determine the structure of words by construing irregularity as a matter of degree, using examples from a diverse range of languages and phenomena to illustrate. Many languages share common word building strategies and many diverge in interesting ways. These strategies can be understood by distinguishing different notions of 'default'. The Network Morphology philosophy promotes the use of computational implementation to check theories. The accompanying website provides the computer coded version of the Network Morphology model of word structure for readers to test, customize and develop. This book will be a valuable contribution to the fields of linguistic typology and morphology and will be welcomed by researchers and graduate students in these areas.

Inflectional morphology plays a paradoxical role in language. On the one hand it tells us useful things, for example that a noun is plural or a verb is in the past tense. On the other hand many languages get along perfectly well without it, so the baroquely ornamented forms we sometimes find come across as a gratuitous over-elaboration. This is especially apparent where the morphological structures operate at cross purposes to the general systems of meaning and function that govern a language, yielding inflection classes and arbitrarily configured paradigms. This is what we call morphological complexity. Manipulating the forms of words requires learning a whole new system of structures and relationships. This book confronts the typological challenge of characterising the wildly diverse sorts of morphological complexity we find in the languages of the world, offering both a unified descriptive framework and quantitative measures that can be applied to such heterogeneous systems.

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 aims to assess the nature of morphological complexity, and the properties that distinguish it from the complexity manifested in other components of language. Of the many ways languages have of being complex, perhaps none is as daunting as what can be achieved by inflectional morphology: this volume examines languages such as Archi, which has a 1,000,000-form verb paradigm, and Chinantec, which has over 100 inflection classes. Alongside this complexity, inflection is notable for its variety across languages: one can take two unrelated languages and discover that they share similar syntax or phonology, but one would be hard pressed to find two unrelated languages with the same inflectional systems. In this volume, senior scholars and junior researchers highlight novel perspectives on conceptualizing morphological complexity, and offer concrete means for measuring, quantifying and analysing it. Examples are drawn from a wide range of languages, including those of North America, New Guinea, Australia, and Asia, alongside a number of European languages. The book will be a valuable resource for all those studying complexity phenomena in morphology, and for theoretical linguists more generally, from graduate level upwards.

Syncretism - where a single form serves two or more morphosyntactic functions - is a persistent problem at the syntax-morphology interface. It results from a 'mismatch' whereby the syntax of a language makes a particular distinction but the morphology does not. This pioneering book provides a full-length study of inflectional syncretism, presenting a typology of its occurrence across a wide range of languages. The implications of syncretism for the syntax-morphology interface have long been recognised: it argues either for an enriched model of feature structure (thereby preserving a direct link between function and form), or for the independence of morphological structure from syntactic structure. This book presents a compelling argument for the autonomy of morphology and the resulting analysis is illustrated in a series of formal case studies within Network Morphology. It will be welcomed by all linguists interested in the relation between words and the larger units of which they are a part.

Deponency is a mismatch between form and function in language that was first described for Latin, where there is a group of verbs (the deponents) which are morphologically passive but syntactically active. This is evidence of a larger problem involving the interface between syntax and morphology: inflectional morphology is supposed to specify syntactic function, but sometimes it sends out the wrong signal. Although the problem is as old as the Western linguistic tradition, no generally accepted account of it has yet been given, and it is safe to say that all current theories of language have been constructed as if deponency did not exist.
In recent years, however, linguists have begun to confront its theoretical implications, albeit largely in isolation from each other. There is as yet no definitive statement of the problem, nor any generally accepted definition of its nature and scope.
This volume brings together the findings of leading scholars working in the area of morphological mismatches, and represents the first book-length typological and theoretical treatment of the topic. It will establish the important role that research on deponency has to play in contemporary linguistics, and set the standard for future work.

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.

An important design feature of language is the use of productive patterns in inflection. In English, we have pairs such as 'enjoy' 'enjoyed', 'agree' 'agreed', and many others. On the basis of this productive pattern, if we meet a new verb 'transduce' we know that there will be the form 'transduced'. Even if the pattern is not fully regular, there will be a form available, as in 'understand' 'understood'. Surprisingly, this principle is sometimes violated, a phenomenon known as defectiveness, which means there is a gap in a word's set of forms: for example, given the verb 'forego', many if not most people are unwilling to produce a past tense.
Although such gaps have been known to us since the days of Classical grammarians, they remain poorly understood. Defectiveness contradicts basic assumptions about the way inflectional rules operate, because it seems to require that speakers know that for certain words, not only should one not employ the expected rule, one should not employ any rule at all. This is a serious problem, since it is probably safe to say that all reigning models of grammar were designed as if defectiveness did not exist, and would lose a considerable amount of their elegance if it were properly factored in.
This volume addressed these issues from a number of analytical approaches - historical, statistical and theoretical - and by using studies from a range of languages.
