The sources of the idioms included here, and of the notations about their grammatical and stylistic properties, were two Russian lexicons: "Tolkovyj Slovar' russkogo jazyka," published in Moscow in 1935, and "Slovar' russkogo jazyka," published in 1957 by the Academy of Sciences of the U.S.S.R. in Moscow. Each entry contains the headword from the source lexicon, printed in capital Cyrillic letters, followed by a two-digit evaluation code that precedes each idiom and refers to stylistic markers such as "argot,""colloquial,""obsolete," etc. Wherever they are available, English equivalents or explanations of the Russian idioms and Russian language examples are also included. The dictionary begins with an explanation of the stylistic evaluation codes and a list of symbols and abbreviations. (PMP)
