Stubbornly and persistently work on expanding your vocabulary. It's not necessary to memorize the contents of dictionaries. Quite a lot to read. Well, if it's classic literature – Leo Tolstoy, Anton Chekhov, Fyodor Dostoevsky, Nikolai Gogol, whose language is the benchmark of Russian literature. Examples of modern printed publications hardly will enrich your vocabulary, although the book published by reputable publishing house, it can bring you significant benefits in vocabulary. Read more good literature.
Get rid of words-parasites. Today they are the scourge of native great and mighty. So here, at the most, as it is, in short, damn, well, that is to say, even the infamous "uh-uh" clog it, stand opposed to the essence, impede the perception. There are many ways of getting rid of words-parasites: fines (at home or in the office), a clear retelling read pages from the book, dealing with people who can do without the "parasites", etc.
Avoid use of foreign words. Don't have to say "diversification of business" when you can say "business expansion" or "preventive measures" when there is a Russian version of "precautionary measures". Of course, sometimes want to show off knowledge of words like merchandising, prolifer, mainstream, teaser, etc. But if you decide to speak correctly in Russian, try to use it Russian words. Of course, the Russian language is highly mobile, foreign words, anyway, get into it, some take root, others do not, but should maintain respect for their native language. About it always reminded Gorky: "Language is a tool we must learn to translate their experiences in a more perfect, bright, simple form... We succeed only when educating a respect for language."
Training correct it, and record himself from time to time on the tape (preferably at a time when you just talk to someone). In the first moments of listening, you may be shocked, don't be alarmed if you don't recognize my own voice. Their own speech may seem obscure, clogged. Remember that trains, develops. Produce not only the correct use of words and phrases, but also pronunciation. For this quite a few times during the day to say tongue twisters.
Pay attention to how the speakers say and the top programs of the Central television and radio broadcasting. Remember the words, the style and figures of speech, manner. Do not hesitate to repeat.
Follow the directives of the Ministry of education of the Russian Federation, underlining the changing norms of the Russian language. Example: the order "On approval of the list of grammars, dictionaries and reference books containing norms of modern literary language when it is used as a state language of the Russian Federation" (2009). You can agree or disagree with the decisions of Ministers concerning the pronunciation of individual words, but aware of the appearance of such official documents (and their content), if you have decided to speak Russian correctly, you should.
