What this sheet practices
Students add a prefix or suffix to a base word and identify how the meaning changes. Knowing that 'un-' means not and '-less' means without turns one known word into several.
Errors worth watching for
- Doubling consonants incorrectly when adding a suffix (runing).
- Changing the base word's meaning instead of applying the affix.
How to use it
- Set the difficulty. Easy narrows the range; challenge adds missing values or extra steps.
- Choose how many questions and how many fit on a page. Ten per page is the most readable default.
- Print, or save as PDF. Replace any single question with the circular arrow if it does not fit your group.

Does spelling count?
Yes. Suffix spelling rules such as dropping a silent e are part of the skill.
Can I print this worksheet on A4 paper?
Yes. Switch Paper to A4 in the settings panel. The layout recalculates the page height and keeps 0.5-inch margins, so nothing is cut off.
Is an answer key included?
The generator always produces an answer key and worked solutions. They are part of the pass; the student sheet can be previewed and printed for free.
