Using a unique approach to building vocabulary skills, you will be introduced to new words by first learning about their Greek or Latin roots. Since most English words derive from those two languages you will not only learn the words defined; you will also develop the ability to understand other words with the same root. For each root that is introduced, several words which derive from it are presented. The definition and pronunciation of each new word are given as are numerous examples showing how each word is used in context. Fun and challenging quizzes let you test your progress as you work your way through each section. The quizzes are structured like those on standardized tests such as the SAT, so for students this is excellent test preparation. For adults, Webster's New Explorer Vocabulary Skill Builder is a means of enriching your everyday vocabulary.
