Designed to help students of Russian increase their knowledge of wordbuilding and, as a result, increase their vocabulary, Roots of the Russian Knowledge includes 450 of the most commonly used roots of the Russian language. After mastering Russian prefixes and suffixes, students develop an ability to construct words and terms from a given Russian root.
Only one other review for this one! It says the book isn't comprehensive enough. That's fair, but I have not come across another book like this and it has proved invaluable in my language learning. I read two pages a week over the course of this year and I am finding myself understanding Russian so much better, as a result. Highly recommended.
This is an A-Z etymological reference book rather than a continuous piece of prose. It has approximately 200 Russian language stems – my only criticism is it isn't comprehensive enough. It is nonetheless interesting.
