The Central Chadic languages are a diverse and fascinating collection of languages, spoken in Nigeria, Cameroon and Chad. The phonologies of these languages have intrigued linguists since they were first studied, due to their minimal sets of phonemic vowels (sometimes only one), complex systems of vowel harmony, and extensive use of palatalized and labialized consonants. Analysis of these languages led to the proposal of phonemic units referred to as ‘prosodies’, which act on both vowels and consonants, allowing Central Chadic phonologies to be described in a neat and succinct way. 0This study looks at the diverse phonological systems found within Central Chadic, and reconstructs the phonological system of their ancestor language. This system is itself simple and succinct, and includes one phonemic prosody and just three phonemic vowels. The study describes the phonological processes that led from this system to the many phonological systems that are in use today, shedding light both on the history of the languages, and on issues in the analysis of these languages.

Drawing on extensive field data, this groundbreaking work explores the development of the sound systems of Central Chadic languages.

Based on the author's life-long research experience, this book unearths the linguistic history of under-researched Central Chadic languages.

Despite earlier work by Trubetzkoy, Jakobson and Greenberg, phonological typology is often underrepresented in typology textbooks. At the same time, most phonologists do not see a difference between phonological typology and cross-linguistic (formal) phonology. The purpose of this book is to bring together leading scholars to address the issue of phonological typology, both in terms of the unity and the diversity of phonological systems.

"Of all of the African language families, the Chadic languages belonging to the Afroasiatic macrofamily are highly internally diverse due to a long history and various scenarios of language contact. This pioneering study explores the development of the sound systems of the 'Central Chadic' languages, a major branch of the Chadic family. Drawing on and comparing field data from 60 different Central Chadic languages, H. Ekkehard Wolff unpacks the specific phonological principles that underpin the Chadic languages' diverse phonological evolution, arguing that their diversity resultsw from historical processes of 'prosodification' of reconstructable segments of the proto-language. It offers meticulous historical analyses of 64 words from Proto-Central Chadic, into up to 60 individual modern languages, including both consonants and vowels. Particular emphasis is on tracing the deep-rooted origin and impact of palatalization and labialization prosodies within a phonological system that, on its deepest level, recognizes only one vowel phoneme"--

Of all of the African language families, the Chadic languages belonging to the Afroasiatic macro-family are highly internally diverse due to a long history and various scenarios of language contact. This pioneering study explores the development of the sound systems of the 'Central Chadic' languages, a major branch of the Chadic family. Drawing on and comparing field data from about 60 different Central Chadic languages, H. Ekkehard Wolff unpacks the specific phonological principles that underpin the Chadic languages' diverse phonological evolution, arguing that their diversity results to no little extent from historical processes of 'prosodification' of reconstructable segments of the proto-language. The book offers meticulous historical analyses of some 60 words from Proto-Central Chadic, in up to 60 individual modern languages, including both consonants and vowels. Particular emphasis is on tracing the deep-rooted origin and impact of palatalisation and labialisation prosodies within a phonological system that, on its deepest level, recognises only one vowel phoneme */a/.

This handbook provides a detailed account of the phenomenon of vowel harmony, a pattern according to which all vowels within a word must agree for some phonological property or properties. Vowel harmony has been central in the development of phonological theories thanks to its cluster of remarkable properties, notably its typically 'unbounded' character and its non-locality, and because it forms part of the phonology of most world languages. The five parts of this volume cover all aspects of vowel harmony from a range of theoretical and methodological perspectives. Part I outlines the types of vowel harmony and some unusual cases, before Part II explores structural issues such as vowel inventories, the interaction of vowel harmony and morphological structure, and locality. The chapters in Part III provide an overview of the various theoretical accounts of the phenomenon, as well as bringing in insights from language acquisition and psycholinguistics, while Part IV focuses on the historical life cycle of vowel harmony, looking at topics such as phonetic factors and the effect of language contact. The final part contains 31 chapters that present data and analysis of vowel harmony across all major language families as well as several isolates, constituting the broadest coverage of the phenomenon to date.
