Vulgar Latin refers to those features of Latin language that were not recommended by the classical grammarians but existed nonetheless. Although Vulgar Latin is not well documented, evidence can be deduced from details of the spelling, grammar, and vocabulary that occur in texts of the later Roman Empire, late antiquity, and the early Middle Ages. Every aspect of Vulgar Latin is exemplified in this book, proving that the language is not separate in itself, but an integral part of Latin.Originally published in French in 1967, Vulgar Latin was translated more recently into Spanish in an expanded and revised version. The English translation by Roger Wright accurately portrays Vulgar Latin as a complicated field of study, where little is known with absolute certainty, but a great deal can be worked out with considerable probability through careful critical analysis of the data. This text is an invaluable aid to research and understanding for all those interested in Latin, Romance languages, historical linguistics, early medieval texts, and early medieval history.József Herman is the former director of the Linguistic Research Institute at the Hungarian Academy of Sciences and is currently Professor of Latin Linguistics at the University of Venice. He is a well-known authority on the history of later Latin and the prehistory of Romance languages
