Grade 3-7 More than 2000 entries with an average of 3 synonyms per entry. Many of the entries include an antonym printed in red type. A section entitled "Using the Thesaurus" explains entry words, guide words, synonyms and antonyms. It also elaborates upon words with more than one meaning and words that are spelled alike. The format is open and non-threatening, making the book accessible to young readers. The black-and-white line drawings are pleasant but unnecessary. Clear and Simple Thesaurus Dictionary (Grosset, 1971) by the same authors has the same format but contains more entries and a more difficult choice of words. A handy and valuable reference book.
