Here’s the solution to the prefix-root matching worksheet, with explanations for each:
---
1. un + known = unknown
✔ *Explanation:* The prefix “un-” means “not.” So, “unknown” means “not known.”
2. re + do = redo
✔ *Explanation:* The prefix “re-” means “again.” So, “redo” means “to do again.”
3. pre + heat = preheat
✔ *Explanation:* The prefix “pre-” means “before.” So, “preheat” means “to heat before use (e.g., an oven).”
4. mis + pronounce = mispronounce
✔ *Explanation:* The prefix “mis-” means “wrongly.” So, “mispronounce” means “to pronounce incorrectly.”
5. dis + honest = dishonest
✔ *Explanation:* The prefix “dis-” means “not” or “opposite of.” So, “dishonest” means “not honest.”
6. im + perfect = imperfect
✔ *Explanation:* The prefix “im-” is a variant of “in-” meaning “not,” used before words starting with “p.” So, “imperfect” means “not perfect.”
7. in + grown = ingrown
✔ *Explanation:* The prefix “in-” means “into” or “within.” So, “ingrown” (as in “ingrown toenail”) means “grown inward or into the surrounding tissue.”
