In A Grammar of Dazaga, Josiah Walters provides the first detailed description and analysis of Dazaga (a Saharan language) in the past half-century. Based on a review of previous work on Dazaga, and with his own more recent data, the author describes the phonology, morphology, and syntax of Dazaga. He provides a new analysis of the categorization of verbs in to classes, demonstrating the prominence of light verb constructions in Dazaga. His analysis of the syntax brings to light several striking features of Dazaga, including optional ergative case marking, mixed alignment of objects, a variety of causative constructions, and verb serialization. Throughout the work, the author relates his findings to work on related languages and to recent typological studies.

Wandala is a hitherto undescribed Central Chadic language spoken in Northern Cameroon and Northeastern Nigeria. The Grammar of Wandala describes, in a non-aprioristic approach, phonology, morphology, syntax, and all functional domains grammaticalized in the language. The grammatical structure of Wandala is quite different from the structure of other Chadic languages described thus far in both the formal means and the functions that have been grammaticalized. The grammar provides proofs for the postulated hypotheses concerning forms and functions. The grammar is written in a style accessible to linguists working within different theoretical frameworks. The phonology is characterized by a rich consonantal system, a three vowel system, and a two tone system. The language has abundant vowel insertion rules and a vowel harmony system. Vowel deletion marks phrase-internal position, and vowel-insertion marks phrase-final position. The two rules allow the parsing of the clause into constituents. The language has three types of reduplication of verbs, two of which code aspectual and modal distinctions. The negative paradigms of verbs differ from affirmative paradigms in the coding of subject. The pronominal affixes and extensive system of verbal extensions code the grammatical and semantic relations within the clause. Wandala has unusual clausal structure, in that in a pragmatically neutral verbal clause, there is only one nominal argument, either the subject or the object. These arguments can follow a variety of constituents. The grammatical role of that argument is coded by inflectional markers on the verb and most interestingly, on whatever lexical or grammatical morpheme precedes the constituent. The markers of grammatical relations added to verbs are different for different classes of verbs.

In A Grammar of Makary Kotoko, Sean Allison provides a thorough description and analysis of Makary Kotoko - a Central Chadic language of Cameroon, framing the discussion within R.M.W. Dixon’s (2010a, 2010b, 2012) Basic Linguistic Theory. Working with an extensive corpus of recorded texts supplemented by interactions with native speakers of the language, the author provides the first full grammar of a Kotoko language. The detailed analysis of the phonology, morphology, syntax, and discourse features of Makary Kotoko is from a functional/typological perspective. Being based on a large number of oral texts, the analysis provides an example-rich description showing the range of variation of the constructions presented while giving insights into Kotoko culture.

Joan Bybee and her colleagues present a new theory of the evolution of grammar that links structure and meaning in a way that directly challenges most contemporary versions of generative grammar. This study focuses on the use and meaning of grammatical markers of tense, aspect, and modality and identifies a universal set of grammatical categories. The authors demonstrate that the semantic content of these categories evolves gradually and that this process of evolution is strikingly similar across unrelated languages. Through a survey of seventy-six languages in twenty-five different phyla, the authors show that the same paths of change occur universally and that movement along these paths is in one direction only. This analysis reveals that lexical substance evolves into grammatical substance through various mechanisms of change, such as metaphorical extension and the conventionalization of implicature. Grammaticization is always accompanied by an increase in frequency of the grammatical marker, providing clear evidence that language use is a major factor in the evolution of synchronic language states. The Evolution of Grammar has important implications for the development of language and for the study of cognitive processes in general.

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.

The papers in this volume in honor of Sandra Annear Thompson deal with complex sentences, an important topic in Thompson’s career. The focus of the contributions is on the ways in which the grammatical properties of complex sentences are shaped by the communicative context in which they are produced, an approach to grammatical analysis that Thompson pioneered and developed in the course of her distinguished career.

This book is based on the results of research in language typology, and motivated by the need for a theory to explain them. Croft proposes intimate links between syntactic and semantic structures, and argues that the basic elements of any language are not syntactic but rather syntactic-semantic "Gestalts." He puts forward a new approach to syntactic representation and a new model of how language and languages work.
