Word Test 149

Improve Your Vocabulary

There is nothing more important in life than being able to master the power of communication. A good vocabulary is a like driving a car with rocket fuel instead of leaded gasoline. Words can power your career into high gear and increase your understanding of others.

From 2002-2014 we posted our Word of the Day and subsequently our Weekend Word Tests for 650 Consecutive Weeks or 12 ½ years, to help our viewers improve and expand their vocabulary. If you are serious about improving your vocabulary, our Word Test Library will challenge you to learn words you may never have known existed.
