Printable worksheet designed to help students learn common prefixes, their definitions, and practice writing their own examples.

Task Explanation:

The task requires you to understand the meanings of common prefixes and provide an example word for each prefix. Prefixes are groups of letters added to the beginning of a root word to change its meaning.

Solution:

Below is the completed table with examples for each prefix:

| dis- | not, opposite of | dislike |
| il-, im-, in-, ir- | not | illegal |
| mid- | middle | midnight |
| mis- | wrongly | misunderstand |
| non- | not | non-toxic |
| over- | above, too much | overreact |
| pre- | before | preheat |
| re- | again | rewrite |
| semi- | half | semifinal |
| sub- | under | submarine |
| un- | not | unhappy |
| under- | below, not enough | underestimate |
