Root Word Builders

In this worksheet, students expand base words by adding suffixes such as -s, -ed, and -ing to create full word families. For each root word like trust, wave, and tap, learners generate three new forms, reinforcing spelling rules and morphological understanding. The exercise builds vocabulary growth, word formation awareness, and grammatical flexibility. It’s an excellent introduction to how prefixes and suffixes modify meaning and function in English.
