Suffix Spelling Changes
A 3rd Grade spelling list that teaches three changes before adding suffixes: dropping final e, doubling a final consonant, and changing final y to i.
These spelling words are a good fit for students who...
- can spell familiar base words before adding endings such as -ing, -ed, -er, and -est
- can identify a short vowel, final silent e, or consonant-plus-y at the end of a base word
- is ready to compare the unchanged base with its suffixed form

Adding an ending becomes easier when a child learns to pause and inspect the base word first. This list gives equal practice to three base-word changes. Making, writing, hoped, and smiled drop final silent e. Running, stopped, sitting, and planned double one final consonant after a short vowel. Carried, cried, happier, and funniest change consonant-plus-y to i before the suffix.
This unit follows the 3rd Grade Suffixes list, which introduces what common suffixes mean and do. Here the focus shifts to the spelling at the join between a familiar base and its suffix. Keeping all three decisions together helps a learner inspect the base first instead of applying one change to every word.
How to practice this list
Write the base word beside the finished word and mark what changed: make → making, run → running, or carry → carried. Mix the three groups and ask your child to name the base-word shape before choosing drop, double, change, or attach unchanged. Include an occasional unchanged comparison such as rain → raining, hope → hopeful, or play → played without adding those words to the practice list.
The learner is ready to continue when they can recover the base, explain which condition triggered a change, and choose the correct operation in a mixed set rather than repeating the most recently practiced rule.
Common questions
Frequently asked questions
- Do all words change before a suffix is added?
- No. The base word's ending and the suffix determine whether a change is needed. Many suffixes attach without changing the base, so learners should inspect the base before choosing an action.
- Why does carrying keep the y?
- Final y normally stays before -ing, so carry becomes carrying. The y-to-i examples on this list use other suffixes, as in carried and happier.
