It is the application of Ozhegov's annotated Russian Dictionary that does not require an Internet connection.
The one-volume explanatory dictionary of the Russian language contains 80,000 words and phraseological expressions (counting heading words, derived words placed in the word-formation nest, and phraseological expressions and idioms following the sign). The words and phraseological units contained in the dictionary refer to the general literary Russian vocabulary, as well as to the special spheres of the language interacting with it; in the dictionary is also widely represented vernacular vocabulary used in literature and colloquial speech. The dictionary entry includes the interpretation of the meaning, characteristics of the structure of a polysemantic word, examples of use, information about the compatibility of the word, grammatical and accentological (if necessary, also orthoepic) characteristics of the word. The dictionary entry is accompanied by a description of those phraseological expressions that are generated by this word or are somehow associated with it.
