This book is made up of three main sections with numerous chapitres. The first section is about the syntax of negation and the particle "ki" (not). The next section deals with the exclusive focus particle "ve " or "he" (only) and the Reduplication of categories like verb for the aim of Focalisation. These two particles sometimes occur in ambiguous sentences. And The last section is a dictionary of Ewondo verbs and their meaning in English. This book will be useful for the comparative study of Bulu, Fang and Ewondo. These languages share many features in common. They have the same verbal system, the same particles and they possess a variety of pronouns (weak and strong). It can be interesting to compare the syntax of Ewondo with the syntax of other bantu languages. In this book, I acknowledge the works of teachers such as Vicki Carstens, Ian Roberts, Richard S. Kayne for their works on comparative syntax and the late Hans Georg Obenauer who was my main teacher when i received my DEA in 1988.
