Sure! Let’s solve this prefix matching worksheet step by step.
The task is to
match each prefix with its correct root word to form a real, meaningful English word — then write the new word in the numbered box below.
---
Step-by-step Matching:
1.
un + known = unknown
→ “Un” means “not,” so “unknown” = not known.
✔
2.
re + do = redo
→ “Re” means “again,” so “redo” = do again.
✔
3.
pre + heat = preheat
→ “Pre” means “before,” so “preheat” = heat before cooking.
✔
4.
mis + pronounce = mispronounce
→ “Mis” means “wrongly,” so “mispronounce” = pronounce incorrectly.
✔
5.
dis + honest = dishonest
→ “Dis” means “not,” so “dishonest” = not honest.
✔
6.
im + perfect = imperfect
→ “Im” is a variant of “in” meaning “not,” so “imperfect” = not perfect.
✔
*(Note: “in” + “perfect” also works, but “im” is the correct match here because “imperfect” is the standard spelling.)*
7.
in + grown = ingrown
→ “In” + “grown” = “ingrown” (e.g., ingrown hair).
