The work presented in this article aims towards a description of the contemporary lexicon of Russian jurisprudence in the 21st century. Legal concepts and terms in the current Russian legal terminology tend to shift within the discursive field, which makes it difficult to systematize legal vocabulary. The lexicon presented in the current study is selected based on the principle of frequency. It is presented as a polylinguistic thesaurus which displays semantics as well as possible use cases in different spheres within the legal field. The terminological system of contemporary Russian law is based in Latin, and this base is still significant for today’s complex world of legal education. The work presented in this article gives educators a tool for quickly correcting terminological errors.
