This dictionary is a revised and supplemented edition of the classic "Dictionary of the Russian Language" by S. I. Ozhegov. The new edition of the Dictionary included about 100,000 words, scientific terms, dialectisms and archaisms, stable phraseological combinations; at the same time, the general structure and nature of the material supply are preserved. New words and expressions reflect not only changes in the socio-political, scientific and cultural life of Russia over the past 40-50 years, but also the current linguistic processes of our time. Compared to the previous edition, in the 28th edition the dictionary has been updated and new dictionary entries have been significantly revised.
