Let’s go through each word one by one.

We need to find the root word — that’s the main part of the word that gives it its basic meaning. The prefix is added to the front and changes or adds to the meaning, but we’re only writing the root word in the second column.

---

1. amoral
- Prefix: “a-” means “not”
- Root: “moral” → so root word = moral

2. debug
- Prefix: “de-” means “remove”
- Root: “bug” → so root word = bug

3. enclose
- Prefix: “en-” means “put into”
- Root: “close” → so root word = close

4. redesign
- Prefix: “re-” means “again”
- Root: “design” → so root word = design

5. preset
- Prefix: “pre-” means “before”
- Root: “set” → so root word = set

6. nonfiction
- Prefix: “non-” means “not”
- Root: “fiction” → so root word = fiction

7. tricycle
- Prefix: “tri-” means “three”
- Root: “cycle” → so root word = cycle

8. unwind
- Prefix: “un-” means “reverse” or “not”
- Root: “wind” → so root word = wind

9. disrespect
- Prefix: “dis-” means “not” or “opposite”
- Root: “respect” → so root word = respect

10. inactive
- Prefix: “in-” means “not”
- Root: “active” → so root word = active
