Widely recognized as the standard work in its field, this volume traces in systematic form the history of the development of the sounds and forms of the Portuguese language from its Latin beginnings. Based upon years of research and painstaking consideration of all the significant publications on the subject, it clarifies a great deal that has been obscure in the transition from Latin to Old Portuguese, to modern Portuguese, and to Brazilian Portuguese. It also helps resolve many of the complex problems of Spanish and general Romance philology. For the second edition of From Latin to Portuguese, the author, Edwin B. Williams, has made substantial additions and revisions, has brought the bibliography up to date, and has utilized the latest research to reevaluate and confirm his original conclusions. In the light of these adjustments and the new material made available by Williams, this extraordinary synthesis must be classified as an indispensable handbook for the student and scholar working in the areas of Portuguese, Hispanic, and Romance philology.

Lloyd presents an historical grammar of Spanish that includes 20th-century research on Romance and Spanish languages. He offers a synthesis of the research that has illuminated much of the phonetic and morphological development of Spanish.
