New Publication: The Phonology of Proto-Central Chadic

Richard Gravina‘s PhD thesis on The Phonology of Proto-Central Chadic has recently been published by LOT. It is available online at

The summary found there says:

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. This 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.

Alongside the publication, there is a website giving 250 reconstructions within Central Chadic with full data. This can be found at
