The paper presents theoretical and methodological solutions and a concrete analysis of elaboration of entries in an unfinished Slovnik spisovneho jazyka slovenskeho (Dictionary of Standard Slovak Language) - his incomplete first volume contains entries a - juzny - that had been prepared by Anton Janosik and Eugen Jona. 63 parts of this dictionary were published in 1946 - 1949 by Matica slovenska. A conclusion that comes out from the analysis of the theory and practice of the dictionary, proves that Eugen Jona by his creative participation on the work has significantly contributed to the development of the Slovak lexicology and lexicography.
