Multilinguals are people who use several languages in their everyday life. Attitudes towards them are very diverse: some consider them gifted or unusually intelligent, while others fear that they are not fully competent in any one language. This can lead to conflicting advice about multilingualism at home, in school, and elsewhere, particularly nowadays when awareness about multilinguals is growing wherever several languages are used, from London and Amsterdam to New York and California. This is the first book which discusses, in lay terms, the reasons behind the beliefs and myths traditionally associated with multilinguals. It is written for the general public and is relevant for families, teachers, and everyone else who ever wondered about multilingualism. The style is light, often witty, but is founded on a thorough knowledge of all the solid academic research on this subject.
