Српски рјечник (Serbian Dictionary) or Lexicon Lexicon serbico-germanico-latinum is the foundational dictionary of the modern Serbian language, compiled by Vuk Stefanović Karadžić and published in two editions (1818 and 1852). It is the first dictionary of the Serbian language that was based on the vernacular, as opposed to the hybrid, literary Slaveno-Serbian language of the time. It contains a wide range of dialectal and ethnographic material.
