Spanish is, with English, one of the most widely spoken languages in the world. It is as a result also one of the most complex and fascinating, with its many geographical and social varieties. This book offers an introduction to the structures and varieties of Spanish, covering all the major levels of linguistic forecasting; considerable attention is also paid to Judeo-Spanish and creoles. No previous knowledge of linguistics is assumed and a glossary of technical terms, in conjunction with exercises and activities, helps to reinforce key points. The book is written specifically with English-speaking learners of Spanish in mind, and readers will find a good deal of practical help in developing skills such as pronunciation and the appropriate use of register.
