What Is the Plural of Quiz

If you’re wondering about the plural of quiz, the correct form is quizzes. The spelling changes from quiz to quizzes because English adds es and doubles the final z. So, you can write one quiz but two quizzes.

This small spelling rule causes a surprising amount of confusion. Many people write quizs because they know that most nouns form their plural by adding s. Others write quizes because they remember that words ending in certain sounds often take es. Neither spelling is correct.

The correct form is quizzes. You’ll see it in school writing, online tests, classroom materials, games, books, and everyday conversation. Oxford lists quizzes as the plural form of quiz.

The good news is that the rule is easy to remember once you see why the spelling changes. This guide explains the rule, shows you natural examples, and covers common mistakes. You’ll also learn how the same spelling pattern works with related words.

Quick Definition

The word quiz is a singular noun that means a short test or a game in which people answer questions. Its plural form is quizzes, which means more than one quiz. Oxford gives quizzes as the standard plural form in American English.

Direct Answer

The correct plural of quiz is quizzes. You write one quiz but two quizzes.

Why Quiz Becomes Quizzes

The spelling can look strange at first. After all, many English nouns simply take s at the end.

For example.

• book becomes books.
• car becomes cars.
• game becomes games.
• question becomes questions.

So why doesn’t quiz become quizs?

The answer comes from the ending of the word. Quiz ends with a single z. When we form the plural, English uses es and doubles the z. That gives us quizzes.

The pattern looks like this.

quiz → quizzes.

The first z stays. A second z is added. Then es is added after the doubled z.

This creates the spelling quizzes.

The same basic spelling pattern appears in some other English words that end in a single z. The doubled z helps keep the spelling clear and supports the pronunciation of the plural form.

Quiz And Quizzes At A Glance

Word or Phrase	Meaning	Example Sentence	When to Use It
Quiz	One test or question game	I took a quiz today.	Use it for one quiz.
Quizzes	More than one test or question game	We have three quizzes this month.	Use it for two or more quizzes.
Quiz question	One question in a quiz	The last quiz question was difficult.	Use it for a single question inside a quiz.

Quiz score	The result from one quiz	My quiz score was 90 percent.	Use it for one result.
Quiz scores	Results from several quizzes	Her quiz scores improved this term.	Use it for multiple results.

The Basic Spelling Rule

English has many plural rules. The most common one is simple. Add s to a singular noun.

For example.

• cat becomes cats.
• desk becomes desks.
• phone becomes phones.
• lesson becomes lessons.

Some words need es instead. This often happens with nouns ending in sounds or letters such as s, x, z, ch, and sh.

For example.

• bus becomes buses.
• box becomes boxes.
• dish becomes dishes.
• match becomes matches.

The word quiz follows this broader pattern but has one extra spelling change. Because it ends in a single z, the z is doubled before the plural ending is added.

So the process is.

quiz → quizz → quizzes.

You don’t normally need to think through each letter every time you write the word. Once you become familiar with the pattern, quizzes will start to look natural.

Oxford’s American English dictionary lists the noun as quiz with the plural form quizzes. It also defines a quiz as an informal test or a competition in which people answer questions.

Why The Extra Z Matters

The extra z isn’t decoration. It is part of the standard spelling.

Compare these forms.

• quiz.
• quizzes.
• quizes.
• quizs.

Only quiz and quizzes are standard forms for the singular and plural noun.

The spelling quizes is a common mistake. It may look reasonable because English often adds es after certain endings. However, the z must be doubled.

The spelling quizs is also incorrect. It simply adds s without following the spelling pattern used by the word.

Think of the final z as needing a partner before the plural ending appears. The single z becomes double z.

That gives you a simple visual memory trick.

One quiz.

Two quizzes.

You can picture the second z as the extra letter that appears when more than one quiz enters the sentence.

What Does Quiz Mean

Before looking deeper at the plural form, it helps to understand the noun itself.

A quiz can be a short test. Students often take quizzes during a class or course. A quiz can check how well someone understands a lesson or topic.

For example.

• We have a math quiz tomorrow.
• I studied for the history quiz.
• The teacher gave us a short quiz.
• She scored well on the science quiz.

A quiz can also be a game or competition. People may answer questions about sports, movies, music, history, geography, or general knowledge.

For example.

• We played a trivia quiz after dinner.
• The website has a fun personality quiz.
• They entered a general knowledge quiz.
• The television show includes a quiz round.

Oxford gives both meanings. In American English, quiz can mean an informal student test. It can also mean a competition or game in which people answer questions.

How To Use Quizzes In A Sentence

Once you know the spelling, using the plural form is straightforward.

Use quizzes when you are talking about two or more tests or question games.

For example.

• The teacher gives us two quizzes each month.
• I have three quizzes this week.
• These quizzes cover the first five chapters.
• The students completed their quizzes before lunch.
• Online quizzes can make practice more interesting.
• The website offers free quizzes about grammar.
• We compared our quiz scores after class.
• The teacher collected all the quizzes at the end of the lesson.

Notice that the plural form works just like other plural nouns. It can follow numbers, words such as several and many, and other expressions that refer to more than one item.

For example.

• two quizzes.
• three quizzes.
• several quizzes.
• many quizzes.
• weekly quizzes.
• short quizzes.
• online quizzes.
• practice quizzes.

Quiz In The Singular Form

Use quiz when you mean one test or one question game.

For example.

• I have a quiz tomorrow.
• She took a quiz after class.
• This quiz has ten questions.
• The quiz was easier than I expected.
• We finished the quiz in twenty minutes.

You can also use a quiz when introducing one countable quiz.

For example.

• The teacher gave us a quiz.
• I found a quiz online.
• He created a quiz for the class.

The word quiz is a countable noun. That means you can talk about one quiz, two quizzes, several quizzes, or many quizzes. Oxford’s grammar materials explain that countable nouns have singular and plural forms.

Quizzes In Everyday English

The word appears in many settings. You might hear it at school, at work, online, or during a game night.

A teacher might say.

• We will have two quizzes this month.

A student might say.

• I need to study for my quizzes.

A website might say.

• Try our new quizzes.

A friend might say.

• Let’s take some trivia quizzes.

A company might use quizzes for training.

• Employees must complete the safety quizzes.

A magazine might publish quizzes for entertainment.

• This month’s quizzes include questions about movies and music.

These examples show that quizzes is not limited to school tests. It can describe any group of two or more quizzes.

Common Mistakes With Quiz

The most common mistakes are easy to spot once you know the rule.

Quizs.

Quizs is incorrect.

The problem is that the word does not normally form its plural by simply adding s. The standard spelling is quizzes.

Incorrect.

• The teacher gave us three quizs.

Correct.

• The teacher gave us three quizzes.

Quizes.

Quizes is also incorrect.

This version gets closer to the correct spelling because it uses es. However, it misses the extra z.

Incorrect.

• We completed five quizes.

Correct.

• We completed five quizzes.

Quizzez.

Quizzez is another incorrect form.

Some people may add another z and then guess at the ending. The correct spelling ends in zzes, not zzez.

Incorrect.

• The website has several quizzez.

Correct.

• The website has several quizzes.

Quizz.

Quizz is not the normal plural form. It can appear in some wordplay or unusual contexts, but it is not the standard plural noun.

For ordinary English writing, use quiz for one and quizzes for more than one.

A Simple Memory Trick

If you often forget the spelling, use this short pattern.

• One quiz.
• Two quizzes.

Think of the plural as adding an extra z before es.

You can also connect it with the sound.

The singular word ends with a short z sound. In the plural, the ending becomes ziz. The spelling zzes helps represent that change.

Another useful trick is to remember the phrase.

• Pop quiz.
• Pop quizzes.

If you can remember pop quizzes, you can usually remember the spelling of the plural form.

Why Not Quizs

It is natural to think that quizs should work. After all, English has many simple plural forms.

We write.

• test becomes tests.
• book becomes books.
• game becomes games.
• class becomes classes.

The issue is that English spelling depends on the ending of the word. The word quiz has an unusual final letter pattern. It needs es, and the z is doubled.

The same kind of issue appears in other words. English has many spelling patterns that developed over time and do not always follow one simple rule.

That is why memorizing a few common forms can save you time.

For this word, the form to remember is simply quizzes.

Quiz As A Verb

There is another reason people sometimes get confused. Quiz is also a verb.

As a verb, it means to ask someone questions. In American English, it can also mean to give someone a short test. Oxford lists quiz as a verb and gives quizzes as the form used with he, she, or it in the present tense.

For example.

• I quiz my students every Friday.
• She quizzes the class after each lesson.
• The teacher quizzes us on new vocabulary.

Notice something important here.

The spelling quizzes can be either a plural noun or a verb form.

Compare these two sentences.

• We completed three quizzes.

Here, quizzes is a plural noun. It means three tests.

• She quizzes her students every Friday.

Here, quizzes is a verb. It means she gives them questions or tests them.

The spelling is the same, but the grammatical role is different.

This is useful to know because you may see quizzes in many different kinds of sentences.

Quizzes And Other Words

The plural form often appears with related words.

Common combinations include.

• online quizzes.
• classroom quizzes.
• practice quizzes.
• trivia quizzes.
• grammar quizzes.
• math quizzes.
• science quizzes.
• reading quizzes.
• vocabulary quizzes.
• personality quizzes.
• weekly quizzes.
• short quizzes.
• pop quizzes.
• quiz questions.
• quiz answers.
• quiz results.
• quiz scores.

These phrases are all natural in American English.

For example.

• The site has several grammar quizzes.
• Our teacher uses short quizzes to review new lessons.
• I took two online quizzes last night.
• Her quiz scores have improved.
• The class discussed the answers after the quizzes.

Quiz Questions And Quiz Answers

A quiz normally contains questions. Those questions may have multiple choice answers, short answers, true or false statements, or other formats.

For example.

• The quiz has ten questions.
• I answered all the quiz questions.
• We checked our quiz answers.
• The teacher explained the difficult questions after the quiz.

When you talk about more than one quiz, you can also talk about the questions and answers from those quizzes.

For example.

• The teacher reviewed the quiz questions.
• We saved the quiz answers for later.
• The website provides answers after the quizzes are completed.

The noun quiz often works as a modifier before another noun. This means it helps describe another noun.

Examples include.

• quiz question.
• quiz answer.
• quiz score.
• quiz result.
• quiz format.
• quiz night.
• quiz show.

The plural can also appear before another noun in some expressions.

For example.

• quiz questions.
• quiz answers.
• quiz results.

English often lets a noun describe another noun. This is common in everyday language and helps keep phrases short.

Quiz Score And Quiz Scores

A quiz score is the result from one quiz.

For example.

• My quiz score was 85 percent.
• Her quiz score improved this week.

When you have results from several quizzes, use quiz scores.

For example.

• My quiz scores have improved this semester.
• The teacher recorded our quiz scores.

Notice that the first noun stays singular in the phrase quiz scores. This is a common pattern in English.

We say.

• quiz scores.
• quiz questions.
• quiz answers.

We do not normally write quizzes scores or quizzes questions when the noun is being used to describe another noun.

This distinction can help you avoid another common mistake.

Pop Quiz And Pop Quizzes

A pop quiz is a short test given without much advance warning. It is common in American school settings.

For example.

• We had a pop quiz in English class.
• The teacher gave us a pop quiz today.
• I wasn’t ready for the pop quiz.

For example.

• Our teacher gives frequent pop quizzes.
• We had three pop quizzes this month.

This phrase is a useful way to remember the spelling because you can clearly see the change from one to more than one.

Quiz Night And Quiz Nights

A quiz night is an event where people answer questions as a game or competition.

For example.

• We went to a quiz night on Friday.
• The restaurant hosts a quiz night every month.

For example.

• The group attends quiz nights around town.

Notice that only night changes in this phrase. The word quiz stays singular because it describes the type of night.

This is a helpful lesson in noun combinations. A noun used before another noun often stays singular even when the second noun is plural.

Compare.

• quiz night.
• quiz nights.
• quiz question.
• quiz questions.
• quiz score.
• quiz scores.

The main noun usually carries the plural ending.

Is Quizzes Always A Noun

No. Quizzes can be a noun or a verb.

As a noun, it refers to more than one test or question game.

• The students completed their quizzes.

As a verb, it describes an action performed by one person or thing.

• The teacher quizzes the students every Friday.

You can tell the difference by looking at the sentence.

If quizzes refers to tests or games, it is a plural noun.

If quizzes describes someone asking questions or testing someone, it is a verb.

This difference is easy to understand once you look at the words around it.

Quizzes In Formal And Informal Writing

The word quizzes works in both casual and formal writing.

You can use it in a school assignment.

• Students must complete all assigned quizzes.

You can use it in a workplace document.

• Employees will complete monthly training quizzes.

There is no need to replace the word with a more formal term. Quiz is a normal English word, and it works in many settings.

Singular And Plural Agreement

The plural form also affects the verb in a sentence.

Use a singular verb with quiz.

• The quiz is difficult.
• The quiz was short.
• This quiz has ten questions.

Use a plural verb with quizzes.

• The quizzes are difficult.
• The quizzes were short.
• These quizzes have ten questions.

This is a basic subject and verb agreement rule.

Compare.

• The quiz is easy.
• The quizzes are easy.

The noun changes from singular to plural, so the verb changes too.

This matters in writing because the wrong verb can make an otherwise correct sentence sound awkward.

Numbers And Quizzes

Numbers make the singular and plural difference easy to see.

Use quiz with one.

• I have one quiz today.
• She took one quiz this morning.

Use quizzes with numbers greater than one.

• I have two quizzes today.
• She took three quizzes this week.
• We completed five quizzes this month.

The same rule works with expressions such as several, many, and a few.

For example.

• We have several quizzes this semester.
• She completed many quizzes online.
• I took a few quizzes for practice.

The plural form clearly tells the reader that more than one quiz is involved.

Why English Doubles The Z

English spelling has several cases where a final consonant is doubled when an ending is added. The exact reason can vary from one spelling pattern to another.

With quiz, the standard plural spelling is quizzes. The doubled z is part of the established spelling of the word.

You don’t need to learn a complicated historical explanation to use it correctly. For everyday writing, the practical rule is enough.

Remember this pattern.

quiz → quizzes.

The same spelling is also seen in the verb.

quiz → quizzes.

For example.

• I quiz my students.
• She quizzes her students.

So the doubled z is not something that appears only in the plural noun. It also appears in the third person singular form of the verb.

Is Quizzes The Only Correct Form

For standard modern American English, quizzes is the correct plural form of quiz. Oxford’s American English dictionary explicitly lists quizzes as the plural.

Forms such as quizs and quizes are not standard spellings for the plural noun.

If you’re writing a school paper, website, email, report, lesson plan, or social media post, use quizzes.

That one spelling choice keeps your writing clear and correct.

A Quick Editing Check

If you’re unsure about the spelling, use this quick check.

Ask yourself if you’re talking about one quiz or more than one.

If it’s one, write.

quiz.

If it’s more than one, write.

quizzes.

Then check the number of z letters.

• Singular.
• quiz.
• Plural.
• quizzes.

The plural has two z letters.

If you see quizs or quizes, change it to quizzes.

This simple check works every time.
