Cooper has a knack for taking subjects that may be dull or difficult for children and presenting them in a simple, lively way. In "Who Put the Cannon in the Courthouse Square?" (1985) and "Where Did You Get Those Eyes?" (1989), she shows children how to become local historians and genealogists. Here, she tackles linguistics, explaining what linguists do, their theories on how languages began, how people learn to speak, accents and dialects, and relationships between languages. She also offers some helpful tips for those who want to learn to speak a new tongue. Encouraging reader involvement from the first sentence, Cooper invites children to pronounce sounds and words in languages from Welsh to Japanese. While kids may not pick this up on their own, language teachers may find it a useful nontraditional introductory approach to making language learning easier and more fun. The appealing jacket illustration and witty drawings inside are positive additions to the light, informal tone of the text. Glossary.
