Due to a long history of contact, the Chadic languages are the internally most diverse of the Afroasiatic language families, especially in terms of their sound systems. In this ground-breaking study, the author draws on his extensive research experience to unpack the morpho-phonological principles that underpin the languages' diverse prosody effects, arguing that massive variation results from diachronic processes called 'prosodification' of segmental units. The study compares data from 66 of the 79 known languages from the Central branch of the Chadic language family, most of them unwritten and under-researched. It traces language changes for 228 lexical items that can be reconstructed from the proto-language's basic vocabulary, unearthing typological features that link Central Chadic to its deep Afroasiatic heritage. It is accompanied by a set of online appendixes, providing the full analytical apparatus of all lexical reconstructions, with explicit identification of each of the diachronic sound changes and processes involved.

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/.

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

This volume explores the question of why languages differ in the meanings expressed by their grammatical systems. It offers a new methodology to explore the differences and the motivations behind the emergence of meanings, based on data from a wide range of languages, including English, French, Polish, Chadic languages, and Sino-Russian idiolects.

Ian Roberts offers a stimulating introduction to our greatest gift as a species: our capacity for articulate language. We are mostly as blissfully unaware of the intricacies of the structure of language as fish are of the water they swim in. We live in a mental ocean of nouns, verbs, quantifiers, morphemes, vowels and other rich, strange and deeply fascinating linguistic objects. This book introduces the reader to this amazing world. Offering a thought-provoking and accessible introduction to the main discoveries and theories about language, the book is aimed at general readers and undergraduates who are curious about linguistics and language. Written in a lively and direct style, technical terms are carefully introduced and explained and the book includes a full glossary. The book covers all the central areas of linguistics, including phonetics, phonology, morphology, syntax, semantics and pragmatics, as well as historical linguistics, sociolinguistics and psycholinguistics.

The Semitic Languages presents a comprehensive survey of the individual languages and language clusters within this language family, from their origins in antiquity to their present-day forms. This second edition has been fully revised, with new chapters and a wealth of additional material. New features include the following: • new introductory chapters on Proto-Semitic grammar and Semitic linguistic typology • an additional chapter on the place of Semitic as a subgroup of Afro-Asiatic, and several chapters on modern forms of Arabic, Aramaic and Ethiopian Semitic • text samples of each individual language, transcribed into the International Phonetic Alphabet, with standard linguistic word-by-word glossing as well as translation • new maps and tables present information visually for easy reference. This unique resource is the ideal reference for advanced undergraduate and postgraduate students of linguistics and language. It will be of interest to researchers and anyone with an interest in historical linguistics, linguistic typology, linguistic anthropology and language development.
