I disagree with this. Considering your reply, I am assuming that you are a native Russian speaker. A perfect example is the "bar" word that I used before. In English there can be a metal bar, bar exam, barred from admission, etc... 1 English word but many Russian words. Consider the phrase "Come on". This can translate a few ways in Russian depending on context. It is all said the same in English. Consider the question "why?" in English. There is 1 English word but there are different ways to say this in Russian. Or the word "run". A person can run in a race, the faucet can be running water, the car can be running, etc... The list goes on and on. And this is just counting root words. I am not even talking about grammar. English does not consider masculine or feminine words or things like this. In English, words will be the same no matter who is being talked to. I think you know what I mean. So the Russian vocabulary is not several times smaller but is actually bigger. This can be confirmed by known fact or simply talking with a Russian.
