ÃÛÌÇÖ±²¥ Linguistics Professor Zygmunt Frajzyngier has produced two landmark studies in African linguistics. The first work is 2012's A Grammar of Wandala (Mouton de Gruyter). This book represents the first description of Wandala, a Central Chadic language spoken in the Far North Province of Cameroon and in North-Eastern Nigeria by about 45,000 speakers. The grammar covers all formal coding means and all functional domains of the language. Wandala shares vocabulary with other Central Chadic languages, but its grammatical system differs significantly from both other Central Chadic languages and Chadic languages generally. The second work, co-edited by Frajzyngier and ÃÛÌÇÖ±²¥ Linguistics Research Assistant Professor Erin Shay is The Afroasiatic Languages (2012; Cambridge University Press). Afroasiatic languages are spoken by some 300 million people in Northern, Central and Eastern Africa and the Middle East. This book is the first typological study of these languages, which comprise around 375 living and extinct varieties. The work contains chapters by eminent scholars of this area on Egyptian and Coptic, Berber, Semitic, Chadic, Cushitic and Omotic. Frajzyngier's concluding chapter provides a typological outline of Afroasiatic languages. Prof. Frajzyngier's other recent accomplishments include the publication by University of Warsaw Press of Wspoldzialanie podsystemów w strukturze jezyka, the Polish edition of Frajzyngier and Shay's 2003  Explaining Language Structure through Systems Interaction (Benjamins) and the funding of a research project  (Amina Mettouchi, PI) by the French Agence National de Recherche, based on the framework elaborated in this work
