Is this a good site for teaching myself some etymology?

Is this site good for learning a href="http://www.betterendings.org/homeschool/Words/Root%20Words.htm" rel="nofollow"http://www.betterendings.org/homeschool/…/a the roots, suffix and prefixes? I want to be able to figure out words by myself, or can you direct me to a better site?
