This study focusses on affixation and auxiliaries in Igbo, drawing on data mainly from Onicha (Onitsha) Igbo. It identifies prefixes, suffixes, interfixes, circumfixes, super/suprafixes, extensional suffixes and auxiliaries in the variety of Igbo studied. The work is presented in two sections: Section 1 discusses affixation, while Section 2 is focused on auxiliary verbs. Section 1 contains five chapters. Chapter 1 is a general introduction that provides some background information regarding O̩ ni̩cha [make sure this word is correct i.e. represented in the spelling of the language, and not just Onicha] Igbo and the speakers of the lect. Chapter 2 an overview of affixation as an important word formation process in world languages. Chapter 3 is the morpho-syntactic analysis of inflectional affixes. Chapter 4 discusses the morphosyntactic characteristics of derivational affixes, while Chapter 5 is concerned with the morpho-syntactic as well as the semantic charateristics of verbal extensions in Igbo. Section 2 is a sole chapter which discusses in a systematic manner the different types of auxiliary verbs, their uses and the effect of their co-occurrence with perfective verb forms.

In twenty-five chapters this book covers phonology, morphology, syntax and semantics. The chapters are organized in four discrete parts: phonology, morphology, syntax and semantics. They are uneven in terms of scope covered, length, the density of their contents and their degrees of difficulty. Each chapter ends with ‘Some References’ relevant to both the topic(s) treated in the chapter, in Igbo linguistics, and in general linguistics.

This study discusses functional categories in Igbo within Noam Chomsky’s Minimalist Program (MP). Chapter 1 includes the introduction of the concept of functional categories and why they take central place in the study of syntax, as well as an overview of the Minimalist Program (MP). Chapter 2 discusses some historical antecedents to MP. It further discusses the economy principles of the MP as well as the place of functional categories within the overall conceptions of the MP model. Chapter 3 discusses five functional categories: Agreement, Tense, Aspect, Negation and Determiner. In chapter 4, the Igbo functional categories within the verbal domain: Tense, Aspect and Negation are discussed. Chapter 5 is an application of the theoretical issues raised in Chapter 2 to the analysis of the functional categories discussed in Chapter 3. One interesting issue discussed in Chapter 5 is the role of tone in realising some of the functional categories in Igbo. Chapter 6 discusses the functional categories within the nominal domain with much emphasis on the determiner. A revised version of the author’s doctoral thesis, some of the conclusions are revolutionary, relevant to debates in the linguistic theory and in Igbo studies in particular, as well as serving as an introduction to MP.

The Landmarks Series is a research and publications outfit funded by the Landmarks Research Foundation to publish recent outstanding doctoral dissertations on any aspect of Nigerian linguistics, languages, literatures and cultures. This study examines causatives in Igbo within the minimalist program. It identifies three types of causative: analytical, morphological and lexical. The book is divided into five chapters. Chapter 1 is the general introduction, while Chapter 2 examines in some details the theory of causativity. Chapters 3, 4 and 5 focus on the analytical, morphological and lexical causative respectively.

Studies in Nigerian Linguistics is a compilation of research papers on topical issues in Nigerian languages and linguistics covering three main areas of research, viz.: Language and Society, Applied Linguistics and Formal Linguistics. The papers in this volume are sectioned as such, even though there are bits of overlapping, especially for some of the papers contained in the first and second sections. The first fifteen (15) papers focus on the major theme of Language and Society in Nigeria. Many of the papers in this section address some peculiar sociolinguistic issues that affect the nation, including the nagging and lingering problem regarding the “language question” for the Nigerian nation even after five decades of the attainment of “Political Independence”, language and national development and language varieties. Section 2 contains papers in Applied Linguistics in its narrow and extended senses. There are papers on language teaching and learning, interference and intraference phenomena, language engineering (with focus on codification), communication disorders, and much more. The third section contains sixteen (16) papers in the core areas of linguistics, including phonology, morphology and syntax of Nigerian languages. Some of the papers address aspects of the phonological and morphosyntactic processes of deletion, affixation, cliticisation, causativisation, complementation, serialisation, agreement, and much more. The phrasal structure and pronominal systems of some languages were also discussed.

This volume is produced in commemoration of the official retirement of Professor Kay Williamson from the Department of Linguistics and Communication Studies, University of Port Harcourt, Nigeria. The contributing essayists cover five main generations of Nigerian linguists. The collection is divided into six sections: Language, history and Society; Applied Linguistics and Orthography Design; Gender and Communication Studies; Stylistics and Literature; Pragmatics, Discourse Analysis and Translation; and Formal Linguistics. Some of the contributors include: Ayo Bamgbose, Okon Essie, Ben Elugbe, P.A. Nwachukwu, E.N. Emenanjo, P. Anagbogu, Chinyere Ohiri-Aniche, O.M. Ndimele, O.G. Harry, Levi Igwe, C.U. Omego, O. Ojukwu, A.U. Weje, O.N. Anyanwu and A. Idafuro.
