Quizes or Quizzes: Correct Spelling, Meaning, and Usage Explained

You finish writing a teacher’s note, a class newsletter, or a blog post about trivia night. Then you reach the plural of quiz and freeze. Does it end in -zes or -zzes?

The answer is quizzes. “Quizes” is a common misspelling, and spell checkers flag it for a reason.

This guide explains why the z doubles, how the rule works for other words, and where the confusion comes from. You will also find examples, common phrases, a comparison table, and a short practice set so the spelling sticks.

Quizes or Quizzes – Quick Answer

Quizzes is the correct plural of quiz. Quizes is not accepted in standard English, in either American or British writing.

Quick rule to remember: one quiz, two quizzes. The z doubles before -es.

The same pattern applies to the verb. She quizzes her students every Monday.

What Does Quiz Mean?

Before we go deeper into spelling, let us fix the meaning. A quiz is a short test of knowledge. It can be written, spoken, or played on a screen.

People use the word in several ways:

• A short test at school. The teacher gave a ten-minute quiz on fractions.
• A game of questions. We joined the pub quiz on Thursday night.
• A set of questions for fun or self-discovery. I took a personality quiz online.
• A verb meaning “to question.” The detective quizzed the witness for an hour.

In every one of these uses, the plural noun is quizzes and the verb form for he, she, or it is also quizzes.

The Origin of Quizes or Quizzes

The word quiz has a murky past. Language historians do not agree on where it came from, and that is part of its charm.

Here is what is generally accepted:

1. Late eighteenth century. Quiz appeared in English meaning an odd or eccentric person, or a prank.
2. Early nineteenth century. It became a verb meaning to mock or tease someone.
3. Mid-nineteenth century. The verb shifted toward “to question,” especially in American schools and colleges.
4. Twentieth century. The noun settled into its modern meaning of a short test or a question-and-answer game, helped along by radio and television quiz shows.

You may have heard a popular story about a Dublin theatre manager who made a bet that he could add a nonsense word to the English language overnight. It is a fun tale, but most word historians treat it as a legend with no solid proof. It is safest to say the origin is unknown.

Why the Origin Matters for Spelling

The origin does not change how the plural is formed. Whatever the source, quiz behaves like any short English noun ending in z. Once you know the plural rules, the spelling becomes predictable instead of random.

British English vs American English Spelling

Many spelling debates split along the Atlantic. Think of color and colour, or center and centre. This is not one of them.

Both varieties use the same forms. The only real difference is usage. In British and Irish English, the pub quiz is a social tradition, while in American English, quiz often points to a short classroom test. The spelling stays identical.

Dictionaries such as Merriam-Webster, Oxford, Cambridge, and Collins all list quizzes as the plural. That consistency is a good sign you can trust it for school, business, and web writing.

Which Spelling Should You Use?

Use quizzes in every situation. There is no formal, informal, regional, or poetic context where “quizes” is the better choice.

Here is a simple decision guide:

• Academic writing: quizzes
• Business emails: quizzes
• Website and SEO content: quizzes
• Social media: quizzes
• Fiction and dialogue: quizzes

A Note on Search Habits

People do search for “quizes” because they are unsure or typing quickly. That does not make it correct. When you write for readers, always choose the standard form. When you write for search, you can mention the misspelling once, as this article does, so readers who search for it find the right answer.

How to Form the Plural of Words Ending in Z

English plurals come with a handful of reliable patterns. Words ending in z have two main behaviors.

Pattern 1: Add -es (Single Z Stays Single)

When the word already ends in a z after a long vowel sound or another consonant, you simply add -es. Sometimes the final z is part of a longer word with a clear vowel.

• waltz → waltzes
• blitz → blitzes
• topaz → topazes
• adz → adzes

Pattern 2: Double the Z, Then Add -es

When a short word ends in one vowel followed by one z, the z often doubles before the ending is added.

• quiz → quizzes
• fez → fezzes
• whiz → whizzes
• buzz already has two z’s, so it only needs -es (buzzes)

Quick Reference Table

The General Plural Rules in Short

If a noun ends in s, x, z, ch, or sh, the plural needs -es. The extra syllable makes the word easier to say. Compare box → boxes, church → churches, dish → dishes, and kiss → kisses.

Why Is the Plural of Quiz Spelled Quizzes?

There are two reasons, and both are worth knowing.

Reason 1: The Sound Needs Help

A word that ends with a hissing sound such as z, s, x, ch, or sh cannot take a bare -s without sounding awkward. Try saying “quizs.” It is hard to pronounce. Adding -es gives you an extra syllable: quiz-zes.

Reason 2: The Short Vowel Needs Protection

In quiz, the letter i makes a short vowel sound, as in kit. English has a common spelling habit: when you add an ending that starts with a vowel to a short word with a short vowel and a single final consonant, you double that consonant.

You already do this in other words:

• run → running
• stop → stopped
• big → bigger
• quiz → quizzed, quizzing, quizzes

If the z did not double, the i could be read as a long vowel, and readers might pronounce it like quize. The double z keeps the short sound in place.

A Detail About the Letters Q and U

Some people ask why quiz counts as having a “single vowel” when it contains both u and i. In English, the qu pair works as one consonant sound (kw). So the only true vowel in the word is i. That is why it follows the same doubling rule as short words such as fez and whiz.

Why “Quizes” Feels Right but Is Not

Many writers produce “quizes” because they follow the simple “add es” rule and forget the doubling step. The result looks logical, which is why the mistake is so widespread. Still, it breaks the pattern that governs quizzed and quizzing, and standard dictionaries do not accept it.

Common Mistakes with Quizes or Quizzes

Even careful writers slip with this word. Here are the errors seen most often, along with easy fixes.

The Apostrophe Trap

A plural noun does not need an apostrophe.

• ❌ The teacher marked all the quiz’s.
• ✅ The teacher marked all the quizzes.

Use an apostrophe only to show possession: the quiz’s final question (one quiz), or the quizzes’ answer keys (many quizzes).

Self-Check Before Publishing

1. Is the word plural? Then it needs zz before es.
2. Is it a verb ending in -ing or -ed? Double the z again.
3. Is it singular? Use one z.
