Research and Documentation of the Latin Language of the Middle Ages

The Dictionary of Medieval Latin (Mittellateinisches Wörterbuch, MLW) addresses Latin texts that were created between 500 AD and 1280 AD in the German-speaking area, existing in edited versions.

The Mittellateinische Wörterbuch is the largest of 20 national dictionaries on medieval Latinity, compiled in Europe under the aegis of the Union Académique Internationale (UAI) (see also Medieval Latin Dictionary Projects). 

The dictionary represents a basic research project, established already in 1939 with the Bavarian Academy of Sciences and Humanities (Bayerische Akademie der Wissenschaften (BAdW)). Today, the project is headed by a committee, until 2015 named «Kommission für die Herausgabe eines mittellateinischen Wörterbuches»; an advisory board supports and advises the committee with the project’s implementation. Currently, a scientific staff of eleven associates is developing the dictionary articles. They are supported by a part-time secretary as well as by the former head of department, who is supporting the project essentially pro bono during his retirement.

The Material Assembly

Starting in 1948, the foundation for work on the MLW has been layed: 50 main texts were replicated on slips, about another 2500 were excerpted and indices of text editions were combed. Today, all this amounts to about two million occurences from altogether almost 4000 texts, being available as a base for researching the word meanings.

The dictionary slips are pre-arranged alphabetically, according to authors names and work titles and stored in an archive containing about 1,5 million slips. The library area provides about 10,000 volumes of specialist literature for the associates.

The Publication

In 1959, the first MLW fascicle was published following some preparatory work. Today the publication cycle aims at one or two fascicles each year (published by C. H. Beck, Munich).

As of today (2019), there are three completed volumes available (A–B, C, D–E).

Of volume IV (F–K), already 14 parts (F, G, H, I–intrepidus) are published, which amounts to altogether 49 fascicles or about two thirds of the complete works (see also Publications).

Since August 2020 there ist the additional offer to consult our publications from A-H as PDF files. This service (via MLW Open Access) is free of charge.

MLW digital

In cooperation with the Trier Center for Digital Humanities an online-version of the MLW was developed. Beyond the print issues, the MLW online version is available to the interested since July 2019.

In the first instance, the digitally not available first two volumes (A–B und C) were retro-digitized. The other volumes will gradually follow. 

The MLW online-version includes various search templates, the perspective preface for the published volumes as well as a digital references index and a reference list. Under MLW digital, further information and a link for online access is added for you.

Public Relations

MLW associates attend national and international conventions, they organise their own workshops and conferences, presenting the dictionary’s work. They also advise interested persons in all questions regarding Medieval Latin.

Currently, the Austrian Academy of Sciences is dispatching and funding one employee, the Swiss Academy of Humanities and Social Sciences is regularly financing scholarships to support the project.
