Many English learners get confused between quizes or quizzes because both spellings look almost the same.
This mistake often happens when forming the plural of words, especially when people are unsure whether to add -s or -es.
The correct spelling is important for students, teachers, writers, and anyone creating English content.
The correct form is quizzes, while quizes is not a standard English spelling. In this guide, you will learn the meaning of quiz, the correct plural form, the spelling rule behind the double z, and how to use these words correctly with simple examples.
Quick Answer: Quizes or Quizzes?
The correct spelling is quizzes.
Quiz is the singular form, while quizzes is the plural form used for more than one quiz.
Examples:
- I completed one quiz yesterday.
- The teacher gave us three quizzes this week.
The spelling quizes is incorrect and should not be used in academic writing, professional communication, or online content.
The correct pattern is:
Quiz → Quizzes
What Does Quiz Mean?
A quiz is a short test or activity that contains questions used to check someone’s knowledge, understanding, or skills.
Quizzes are commonly used in different areas, including:
- Education
- Online learning
- Training programs
- Games and competitions
A quiz is usually shorter than a formal exam and focuses on a specific topic.
Examples of Quiz in Sentences
- The teacher prepared a science quiz for the students.
- I completed an English vocabulary quiz online.
- The company gave employees a safety quiz after training.
The word quiz can also be used as a verb. In this form, it means to ask someone questions to test their knowledge.
Example:
- The coach will quiz the players before the final match.
What Is the Plural of Quiz?
The plural form of quiz is quizzes.
When talking about more than one quiz, the final z is doubled before adding -es.
Quiz and Quizzes Comparison
| Form | Usage | Example |
|---|---|---|
| Quiz | One test or activity | I took a quiz today. |
| Quizzes | More than one test or activity | We completed five quizzes. |
More Examples:
- Our teacher gives weekly quizzes to check our progress.
- These online quizzes help students practice grammar.
- The website contains fun personality quizzes.
The plural spelling may look unusual, but quizzes follows standard English spelling rules.
Why Does Quiz Become Quizzes?
The spelling change happens because of how English forms plurals.
When a word ends with z, English usually doubles the final z before adding -es. This keeps the spelling and pronunciation clear.
The correct formation is:
Quiz + es = Quizzes
Not:
Quiz + es = Quizes
The same pattern appears in other words:
- Buzz → Buzzes
- Fizz → Fizzes
This is why the correct spelling contains two z letters:
Q-U-I-Z-Z-E-S
Quiz vs Quizzes: Understanding the Difference
The difference between quiz and quizzes is based on quantity.
Quiz (Singular)
Use quiz when referring to one test or question activity.
Examples:
- I have a math quiz tomorrow.
- She passed the driving theory quiz.
Quizzes (Plural)
Use quizzes when referring to two or more tests or activities.
Examples:
- Students complete several quizzes during the course.
- The teacher reviewed all the quizzes before grading.
Choosing between these two words depends on whether you are talking about one quiz or multiple quizzes.
Why “Quizes” Is Wrong
Many people write quizes because they think the plural form of quiz should be created by simply adding -es. However, this spelling does not follow standard English rules.
The correct plural form is quizzes, with two z letters.
Incorrect:
The students completed three quizes.
Correct:
The students completed three quizzes.
The mistake happens because the pronunciation does not change much, so the missing z is easy to overlook. However, spelling is not based only on sound. English words also follow written patterns that help maintain consistency.
According to trusted dictionary sources such as Oxford English Dictionary and Collins Dictionary, the accepted plural form is quizzes.
Common Mistakes With Quiz Spelling
Writing Quizes Instead of Quizzes
This is the most common spelling error.
Many writers remove one z and write:
❌ Quizes
The correct spelling is:
✅ Quizzes
Example:
Incorrect:
The teacher created online quizes for the class.
Correct:
The teacher created online quizzes for the class.
Using Quizs as the Plural Form
Another common mistake is adding only -s.
Incorrect:
The website has many quizs.
Correct:
The website has many quizzes.
Because quiz ends with the letter z, it requires -es with a doubled final letter.
Quiz’s vs Quizzes: What Is the Difference?
Although quizzes and quiz’s look similar, they have completely different meanings.
Quizzes
Quizzes is the plural form of quiz. It means more than one quiz.
Example:
I completed two quizzes before the final exam.
Here, the word refers to multiple tests.
Quiz’s
Quiz’s uses an apostrophe and shows possession. It means something belongs to one quiz.
Examples:
The quiz’s questions were difficult.
Meaning:
The questions belong to one quiz.
Another example:
The quiz’s answer key was missing.
The apostrophe changes the meaning, so quiz’s cannot replace quizzes.
Quizzes in American and British English
The spelling of quizzes is the same in both American English and British English.
There is no difference like:
- color vs colour
- center vs centre
Both varieties use:
Quiz → Quizzes
Examples:
American English:
Students take online quizzes throughout the semester.
British English:
Students take online quizzes throughout the semester.
Whether you are writing for readers in the United States, the United Kingdom, or other English-speaking countries, quizzes is the correct spelling.
