When I was a little boy and a teenager I read a lot. And after that I managed to speak and build my phrases in such a way that even adults were surprised. Subsequently, I had to simplify my spoken language in order to speak as an ordinary person. So my recommendation for you is if you want to increase your vocabulary then you need to read, read and read. But do not forget that the spoken language is much easier. What you get from reading will be mostly your passive vocabulary, but will allow you to become fluent.

I agreed with Max.Reading it's a good practice, but don't forget about alphabet,we have Cyrillic letter.And if you write for example: meditation- медитация (meditaciya),you will see it's a same word,only different ending.Remember, most words with ending -TION (eng) have always ending -ЦИЯ(-CIYA) (rus).Try and you will see it's easy. And doesn't matter what is a language ( mean European),a lot of words came from Latin(Roman). That a small HACK,how to learn language.I use that and I hope that will help you.Good luck!
