[eng] This paper, based on the sources of the Glossarium Mediae Latinitatis Cataloniae, brought together in the digital corpus Corpus Documentale Latinum Cataloniae
(CODOLCAT), aims to show how lexical databases can also contribute to the
study of toponymy and territory, as well as to clarify inherent difficulties. To this
end, two different examples are provided with their respective proposed resolutions: the first identifies and locates two toponyms, and the second focuses on a
single-instance toponym.
