This commemorative volume is the 12th edition in the Nigerian Linguists Festschrift Series devoted to Professor (Mrs.) Appolonia Uzoaku Okwudishu. The majority of the papers were presented at the 27th Annual Conference of the Linguistic Association of Nigerian (CLAN) which was held at the Benue State University, Makurdi, Nigeria, and the 26th CLAN which was held at the University of Ibadan, Nigeria. The title derives from the theme of the 27th CLAN: Language Endangerment: Globalisation and the Fate of Minority Languages in Nigeria. A large number of the papers address the major theme of the conference, while the balance address various aspects of Nigerian linguistics, languages, communication, and literature. Fifty-one papers are included, ranging from sociolinguistics through applied linguistics to formal areas of linguistics which include phonology, morphology and syntax of Nigerian languages. Papers on language endangerment and language revitalisation strategies for safeguarding the vanishing indigenous tongues of Nigeria are the major focus, and the book serves as important reference material in various aspects of language and linguistic studies in Nigeria.
