Haitian Creole is the creole language with the largest number of speakers: about ten million in Haiti and two million in diaspora communities in North American, France, and the Caribbean, including the Dominican Republic, Cuba, and the French overseas departments. Haitian Creole presents a comprehensive view of the structure and development of Haitian Creole. It provides a detailed analysis of the phonology and grammar of the language and points out key differences between these two fundamental aspects of the language and corresponding features of French, its original target language. The book contains a detailed description of the productive strategies of vocabulary development and deals with the origin of Haitian Creole, as well as its relationship to the other French-based creoles in Louisiana, the Caribbean, French Guiana, and the Indian Ocean. A signal innovation with regard to other descriptions of the language is the treatment of linguistic variation, both in geographical dialects and variation as determined by social factors, as well as the presentation of earlier forms of Haitian Creole, as attested by texts from the Colonial period. Another major contribution is the discussion of language planning and related issues concerning the use of Haitian Creole in education and its status relative to French, the other officially recognized language of Haiti.
