The studies assembled in this volume in honor of József Herman address the main areas on which his research has concentrated: the evolution of classical and post-classical Latin, the emergence of the Romance languages, and (from this perspective) more general problems of diachronic linguistics. Over and above the individual problems addressed here in detail, the articles (grouped thematically) outline the concerns of the disciplines involved and establish the present state of research on a number of the issues discussed. Most of the authors have chosen a historical approach, but this does not exclude typological considerations. The collection as a whole is slanted toward the sources of knowledge of vulgar and late Latin and to various questions of syntax and style.
