Much of the English language (and any language I am sure) is simply repeating the same words over and over. The average American will use about 3,000 words, however the dictionary contains about 50 times as many words. What is the benefit of increasing your vocabulary? Well, if you are a student taking the SAT the answer is obvious. However, even if you just want to learn a new language or learn a new subject in school such as anatomy or geology having a larger vocabulary will help you.
