Phi-features, such as person, number, and gender, present a rare opportunity for syntacticians, morphologists and semanticists to collaborate on a research enterprise in which they all have an equal stake and which they all approach with data and insights from their own fields. This volume is the first to attempt to bring together these different strands and styles of research. It presents the core questions, major results, and new directions of this emergent area of linguistic theory and shows how Phi Theory casts light on the nature of interfaces and the structure of the grammar. The book will interest scholars and students of all aspects of linguistic theory at graduate level and above.

Number is a major research domain in semantics, syntax and morphology. However, no current theory of number is applicable to all three fields. In this work, the author argues that a unified theory is not only possible, but necessary for the study of Universal Grammar. Through insightful analysis of unfamiliar data, the author shows that one and the same feature set is implicated in semantic and morphological number phenomena alike, with syntax acting as the conduit between the two. At the heart of the study is an original treatment of Kiowa, a North American language with a remarkable constellation of characteristics, including semantically based noun classification and complex agreement morphology.

This volume presents: (1) the foundations of a unified morphosemantic theory of number; (2) insight into the flow of information from the lexicon, via syntax, into the morphology; (3) wide-ranging topics: nominal semantics, noun classes, DP syntax, agreement, suppletion, complex morphology.

What is the nature of syntactic structure? Why do some languages have radically free word order ('nonconfigurationality')? Do parameters vary independently (the micro-view) or can they co-vary en masse (the macro-view)? Mirrors and Microparameters examines these questions by looking beyond the definitional criterion of nonconfigurationality - that arguments may be freely ordered, omitted, and split. Drawing on newly discovered data from Kiowa, a member of the largely undescribed Kiowa-Tanoan language family, the book reveals that classically nonconfigurational languages can nonetheless exhibit robustly configurational effects. Reconciling the cooccurrence of such freedom with such rigidity has major implications for the Principles and Parameters program. This novel approach to nonconfigurational languages challenges widespread assumptions of linguistic theory and throws light on the syntactic structures, ordering principles, and nature of parametrization that comprise Universal Grammar.

A groundbreaking, comprehensive formal theory of grammatical person that recasts its empirical foundations and re-envisions its theoretical core. Impossible Persons, Daniel Harbour's comprehensive and groundbreaking formal theory of grammatical person, upends understanding of a universal and ubiquitous grammatical category. Breaking with much past work, Harbour establishes three core theses, one empirical, one theoretical, and one metatheoretical. Together, these redefine the data subsumed under the rubric of "person," simplify the feature inventory that a theory of person must posit, and restructure the metatheory in which feature theory as a whole resides. At its heart, Impossible Persons poses a simple question of the possible versus the actual: in how many ways could languages configure their person systems, in how many do they configure them, and what explains the size and shape of the shortfall? Harbour's empirical thesis-that the primary object of study for persons are partitions, not syncretisms-transforms a sea of data into a categorical problem of the attested and the absent. Positing, innovatively, that features denote actions, not predicates, he shows that two features alone generate all and only the attested systems. This apparently poor inventory yields rich explanatory dividends, covering the morphological composition of person, its interaction with number, its connection to space, and properties of its semantics and linearization. Moreover, the core properties of this approach are shared with Harbour's earlier work on number features. Jointly, these results establish an important metatheoretical corollary concerning the balance between richness of feature semantics and restrictiveness of feature inventories. This corollary holds deep implications for how linguists should approach feature theory in future.
