In paper, a Latin-German-Czech glossary is presented which follows the Latin monolingual glossary Catholicon by Johannes Balbus of Genoa in a Brno manuscript stored in the City Archive of Brno, Manuscript Collection No. 115. The trilingual glossary is a Czech adaptation of two Latin-German glossaries called Abstractum and Abba.
A transliterated edition of the glossary accompanied by a critical apparatus is also contained in the study.
