I have been using this book for almost a year now, and it has really helped me in learning the various forms of nouns and verbs. I just pick it up several times a day when I get bored or need a break, and peruse the various entries. By this effortless process, I am able to familiarize myself with a lot of Russian words in a short amount of time. Great buy!

a MUST for students
A fantastic resource that fully declines and conjugates all parts of speech, showing any irregularities in spelling or usage. It also lists perfective/imperfective pairs for all verbs as well as adverbial forms. Essentially if you have a question this book has the answer-- well worth the price!
