The authors discuss the different sorts of multilingualism observed in the city of Brussels. They analyse the multiple ways it can be acquired; the advantages of multilingualism and some of the disadvantages one can read in literature. They propose another angle of the survey of F. Grosjean (in this issue) on the different types ofmultilingualism, and its impact on stuttering in a therapeutic setting. As some caretakers still belief that multilingualism is a probable source of stuttering, the authors analyse those misconceptions and refute them.
