The comparative syntax of A70 languages Fang Ewondo and Bulu is a study of three languages spoken in Cameroon, Gabon and Equatorial Guinea. This study explores some aspects of the minimalist syntax such as External Merge and Internal Merge, the deletion of copies in multiple agreement constructions. It shows lists of verbs that can take an infinitival complement. These languages have a special type of coordination that can help to understand the theory of binding and partial control. There are two other comparative studies of these three languages : their negative strategies and their particles of focalisation.
