Which text would best illustrate manipulation of a base word across related forms, such as berry in berry, berries, berrying?

• A. Polar Bear, Polar Bear, What Do You Hear?
• B. Jamberry
• C. The Very Hungry Caterpillar
• D. Green Eggs and Ham

Answer: (C)

Seeing how a base word can change to express different meanings helps young readers notice word patterns. The Very Hungry Caterpillar uses a simple, repetitive vocabulary that includes foods like berries in both singular and plural contexts. This setup makes the base word berry clearly visible as it morphs into related forms (berry becoming berries) within familiar, concrete language. The book’s predictable structure and everyday vocabulary give children a tangible way to observe how a word can be altered to fit meaning in different situations, which is exactly what this item is asking about. By contrast, the other options emphasize rhyme, repetition, or brand names rather than demonstrating how a base word forms related variants.
