Negative prefixes flip a word's meaning, and this set makes you prove you can spot when something is off. You'll fix sentences where someone is displeased but celebrating, where a nonfiction book tells a dragon tale, and where oversleeping somehow makes you early. Then you'll fill in blanks for unclear, disagree, nonsmoking, and overwater.
Two short-answer prompts ask you to explain dis-, give two examples, and compare un- with non- using a word like nonessential. Once you trust un-, dis-, non-, and over-, the prefix in front of any new word becomes a real clue instead of a guess.

Roots, Prefixes & Suffixes
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
The student was displeased with her grade, so she celebrated happily.
Rewrite: The student was displeased with her grade, so she asked the teacher how to improve.
2. Fix the sentence:
The nonfiction book told an imaginary story about a dragon and a wizard.
Rewrite: The nonfiction book told a true story based on real events and facts.
3. Fix the sentence:
He overslept and arrived at school thirty minutes early.
Rewrite: He overslept and arrived at school thirty minutes late.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. The prefix un- means "not," so if something is unclear, it is not clear.
2. Adding the prefix dis- to "agree" creates disagree, which means to have a different opinion.
3. A nonsmoking area in an airport is a section where smoking is not allowed, because non- means not.
4. The prefix over- means "too much," so to overwater a plant means to give it too much water.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. Explain what the prefix dis- means and give two words that use it. Tell what each word means.
The prefix dis- means "not" or "the opposite of." The word disconnect means to separate something that was joined. The word dishonest means not honest or truthful.
2. How are the prefixes un- and non- alike? How can knowing them help you figure out new words? Give an example.
Both un- and non- mean "not." If I see the word "nonessential," I know it means not essential or not required, even if I have never seen the word before.
