Basic Dictionary of American English (Webster's New World) : Webster's New World Basic Dictionary of American English defines 49,000 of the most commonly used words in the American English lexicon. These are the words adult readers are most likely to encounter in newspapers and magazines, on job applications and product instructions, on advertising billboards and their children's school progress reports. The dictionary defines these words in clear, easy-to-understand language, using only words that are themselves defined in the dictionary, but never condescending to the adult reader. Definitions are liberally supplemented with example phrases and sentences that put words in context and help new readers understand meaning and usage. Special notes on synonyms help new readers differentiate between words with similar meanings. And selected illustrations help readers identify and remember words.
