A delightful romp through the world of words (language, vocabulary, terminology) as readers follow young Thesaurus Rex through his busy day exploring his world and the words that can be used to describe his actions. “Thesaurus Rex starts his day stretching, reaching, extending, bending. Uh oh, his pants need mending!” There are four synonyms for each word, and at least one of these will be familiar. Steinberg has chosen excellent synonyms that will help children extend their vocabulary—foraging, slither, frolic, gnaw, scour, hurtle. Marvelous onomatopoeia is used throughout, as when he gets stuck in the mud: “Thesaurus Rex calls his Mom: howl, yowl, squeal, and shout. Whoosh, plop! She pulls him out.” The humorous illustrations are brightly colored and will help young children see the meanings of the new words. Harter is a master at depicting facial expressions—readers will have no trouble in identifying with the dinosaur tyke. Great, super, terrific, cool. (Picture book. 2-7)
