In science, there is such a thing as information redundancy. Information redundancy actually useful. It's like insurance. If something happens where the failure information, and the rest will fill this gap and the meaning is not distorted. In full respect to this language. The average language has about 300,000 words (English, as the development and spread recently to celebrate the anniversary? Million words).

But the average person uses in everyday speech 15-17 thousand words. Same AS Pushkin in all his works used about 21 thousand words. So what? And nothing! Wrote a brilliant novel. That is, for fluency in a foreign language, I stress, free enough to learn no more than 17 thousand words! On this basis, we can construct a method of teaching foreign language to a qualitatively new basis. In it all, do not learn quickly, and somehow as much as possible words, and learn a little bit, but qualitatively. That is, teaches, so long as a minimum will be learned, as they say, forever. After that, a student who decides whether it is enough of this vocabulary for its needs or not.

Not enough? Well, learn more. As Studies show that properly chosen only 400 words can replace 90% of the total vocabulary, which will be used later. Unbelievable huh? Go ahead! In speaking about forty words cover about 50% (!) Of all vocabulary speech. A 200 words? already 80%, 400, as already mentioned? 90%, and a thousand? 95%. It is easily seen, building vocabulary after a minimum leads to only a slight increase in percentage of used vocabulary.
