Prefix matching worksheet for educational use.

Task Explanation:

The task requires you to match prefixes with root words and form new words by combining them. Prefixes are added to the beginning of a root word to change its meaning. Here's how to solve it step by step:

Step-by-Step Solution:

1. Prefix: Un, Root Word: connect
- "Un-" means "not" or "opposite of."
- Combining "un-" with "connect" forms the word: disconnect.

2. Prefix: In, Root Word: stick
- "In-" often means "into" or "within."
- Combining "in-" with "stick" forms the word: insert.

3. Prefix: Dis, Root Word: circle
- "Dis-" often means "apart" or "away from."
- Combining "dis-" with "circle" forms the word: discircle (though this is less common; a more familiar example might be "disperse").

4. Prefix: Im, Root Word: likely
- "Im-" is used with words starting with "l" and means "not" or "without."
- Combining "im-" with "likely" forms the word: impossible.

5. Prefix: Il, Root Word: moral
- "Il-" is used with words starting with "m" and means "not."
- Combining "il-" with "moral" forms the word: immoral.

6. Prefix: Ir, Root Word: dated
- "Ir-" is used with words starting with "r" and means "not."
- Combining "ir-" with "dated" forms the word: irrelevant.

7. Prefix: Non, Root Word: view
- "Non-" means "not" or "without."
- Combining "non-" with "view" forms the word: non-view (though this is not a standard word; a more common example might be "non-voter").

8. Prefix: Semi, Root Word: regular
- "Semi-" means "half" or "partially."
- Combining "semi-" with "regular" forms the word: semi-regular.

9. Prefix: Pre, Root Word: legal
- "Pre-" means "before."
- Combining "pre-" with "legal" forms the word: pre-legal (though this is not a standard word; a more common example might be "pre-law").

10. Prefix: Post, Root Word: sufficient
- "Post-" means "after."
- Combining "post-" with "sufficient" forms the word: post-sufficient (though this is not a standard word; a more common example might be "post-war").

Final Answer:

Here are the completed words:

1. Un + connect = disconnect
2. In + stick = insert
3. Dis + circle = discircle
4. Im + likely = impossible
5. Il + moral = immoral
6. Ir + dated = irrelevant
7. Non + view = non-view
8. Semi + regular = semi-regular
9. Pre + legal = pre-legal
10. Post + sufficient = post-sufficient
