Johannes, Shelli R. Theo Thesaurus: The Dinosaur Who Loved Big Words. Illustrated by Mike Moran. Philomel Books, 2021. Unpaged. 978-0-593-20551-8 $17.99 Grades K-2.

Theo and his parents are migrating, and his parents are excited, but Theo is worried about joining a new class where no one knows him. He and his parents are a special species of dinosaurs called Thesauruses–self-described ‘logo maniacs’ or word-lovers. Sure enough, Theo’s big words create a barrier between him and his new classmates. He tries to be friendly.  “Salutations!” he greets them; ‘Could you lead me to the athenaeum (library)?” in class; “Care for a crudite (raw snack)?” at lunch; “want to play conceal and search (hide and seek)?” at recess. Everything leads to misconceptions and confusion.  He keeps trying, even inviting them: “I request your attendance to celebrate the anniversary of my hatching.” When the birthday party arrives, but no friends do, Theo tries several words to describe his emotions but discovers he is speechless.  Then the doorbell rings and his classmates arrive, shouting, “Salutations!” Theo and his parents are equally excited to party with his new friends.

THOUGHTS: This is a cute concept, but the words used require explaining to K-2 readers for them to fully understand the humor. Also, Theo’s parents want to be helpful (but seem to miss the mark), while it is unclear what changes the minds of Theo’s classmates. A glossary of Theo’s “thesaurus” style words is included. Supplemental purchase.
