Following the success of 100 Words Every High School Graduate Should Know, the editors of the American Heritage® Dictionaries have developed this new book of 100 words tailored especially to high school freshmen. This second book in the 100 Words series focuses on the kinds of words that a successful middle school graduate can learn from rigorous coursework in a variety of subjects and that nearly every freshman will encounter over the course of the school year.The words have been chosen with various criteria in mind. Some represent key concepts in important areas of the curriculum, while others are more familiar in meaning but present challenges of spelling or usage. All are words that students can expect to see regularly in their high school reading and beyond. And each word is fully defined as well as shown in typical contexts with example sentences and quotations, many of which are taken from award-winning authors such as Harper Lee, George Orwell, Katherine Paterson, and John Knowles. Together, these 100 words represent the increasingly sophisticated and complex vocabulary that freshmen must master as they continue their education at the next level. To learn them is not only to gain useful knowledge — it is to step into a broader world.
