Join Prefix and Root Words | Turtle Diary Worksheet - Free Printable

Problem Overview:

The task is to match each prefix with its corresponding root word and then write the new words formed by combining them. The prefixes and root words are listed in two columns, and the goal is to create meaningful words by pairing them correctly.

Prefixes:

1. un-
2. re-
3. pre-
4. mis-
5. dis-
6. im-
7. in-

Root Words:

1. known
2. heat
3. do
4. pronounce
5. perfect
6. grown
7. honest

Solution Approach:

1. Understand the meaning of each prefix:
- un-: Means "not" or "opposite of."
- re-: Means "again" or "back."
- pre-: Means "before."
- mis-: Means "wrongly" or "badly."
- dis-: Means "apart," "away," or "not."
- im-: Means "not" (often used with Latin roots).
- in-: Means "not" or "into."

2. Match prefixes with root words to form meaningful words:
- Ensure the combination makes logical sense based on the meaning of the prefix and root word.

3. Write the new words in the provided boxes.

Step-by-Step Matching:

1. un- + known → unknown
- Meaning: Not known.

2. re- + heat → reheat
- Meaning: Heat again.

3. pre- + do → pre-do
- Meaning: Do something beforehand.

4. mis- + pronounce → mispronounce
- Meaning: Pronounce incorrectly.

5. dis- + perfect → imperfect
- Note: Although "dis-" can mean "not," it doesn't naturally pair with "perfect." Instead, use "im-" for this case.
- Correct pairing: im- + perfect → imperfect
- Meaning: Not perfect.

6. im- + grown → immature
- Note: "Im-" typically pairs with Latin roots. Here, "grown" is not a Latin root, so this pairing is incorrect.
- Correct pairing: un- + grown → ungrown
- Meaning: Not grown.

7. in- + honest → dishonest
- Note: "In-" means "not," but it doesn't naturally pair with "honest." Instead, use "dis-."
- Correct pairing: dis- + honest → dishonest
- Meaning: Not honest.

Correct Pairings:

1. un- + known → unknown
2. re- + heat → reheat
3. pre- + do → pre-do
4. mis- + pronounce → mispronounce
5. im- + perfect → imperfect
6. un- + grown → ungrown
7. dis- + honest → dishonest
