Etymological Dictionary of Old French
Dictionnaire étymologique de l’ancien français (DEAF)

The Research Unit is in the process of compiling an historical dictionary of medieval French covering the entire vocabulary from the earliest linguistic monuments (the Strasbourg Oaths of 842) to the middle of the 14th century. It records all known word-meanings, groups the vocabulary etymologically into word families and relates it to the history of French and the Romance languages. The indication of links with Middle Latin and loan material from other European languages as well as references to the material culture of the period represent additional contributions to the European history of ideas.
