Dictionarium quatuor linguarum

Dictionarium quatuor linguarum[notes 1] (The Dictionary of Four Languages) is a 16th-century book by the German polymath Hieronymus Megiser that includes a multilingual dictionary and a multilingual grammar of Italian, Slovene, German,[2] and Latin.

[3] It was compiled and published in 1592 in Graz (Austria), then part of the Habsburg monarchy.

The appendix, named Exempla aliquot declinationum et coniugationium (Some examples of declensions and conjugations) contains some grammar of the included languages and has been recognised as the second grammar of Slovene and the first multilingual grammar that includes Slovene.

[5] An extended edition was published under the same title in 1744 at Klagenfurt (Austria) by the Jesuits.

This second edition also contains example phrases in German and Slovene, illustrating the use of the entries given.
