There are only about 200,000 words in the Russian language. This number has doubled since the 19th century, when only 50,000-100,000 words were recorded in dictionaries. This number is very small compared to the English language, which is comprised of over 1,000,000 words. Russians actually use very few of these words, and you will find that due to this many words have more than one meaning.
