This dictionary was produced on the basis of experience gained from the compilation of similar dictionaries of Mari (2002), Mordvin (2004) and Chuvash (2009) at the University of Turku, Finland. The material of the reverse dictionary is arranged in three columns: 1. word, 2. word class and 3. sources.
