This book functions as both a translation dictionary and a thesaurus. With 3,781 entries and 14,000 translations and synonyms, it is not only the first translation dictionary to go from English to Jamaican Creole (Patois), but also the first book that can function as a Jamaican thesaurus. The Jamaicasaurus is thus an essential resource for anyone interested in Jamaican culture and language, whether local or foreigner, as it marks a new milestone for this dialect of increasing global interest while also serving native speakers searching for alternate words and expressions, recent slang, and old terms from the past. To use this book as a thesaurus, simply look up the English equivalent of the Jamaican word or phrase you have in mind to see the various Jamaican synonyms listed. The appendix at the back of the book additionally features lists of Jamaican expletives and exclamations, from mild to vulgar; odd curiosities; and the local Jamaican names for 278 important species of plants and trees used in Jamaica for food, medicine, and cultural purposes (listed by scientific name first). Furthermore, and quite importantly, the Jamaicasaurus bridges the gap between the common English-based way of writing Patois words and the Cassidy-JLU (or 'Jamiekan') system developed by Jamaican linguists to more consistently and accurately represent how those words really sound. This version of the book uses that latter format, the Jamiekan format. It's easy to learn and worth trying. Another edition of the Jamaicasaurus, featuring common English-based spellings, is also available. It has a black cover.
