Many writers pause here because the plural looks like it should follow the usual pattern of adding an s or es. If you have ever deleted this word three times and still felt unsure, you are not alone.
This article answers the question of quizes or quizzes right away, then explains the rule behind the answer. You will see how the plural of quiz works, how the verb forms change, where the word came from, and which mistakes are easy to avoid. By the end, you will know why quizzes has two z’s and be able to spell it with confidence in emails, essays, and online posts.
Quizes or Quizzes – Quick Answer
The correct spelling is quizzes. The word “quizes” is not listed in standard American or British dictionaries, so it counts as a spelling mistake. If you need the plural of quiz, always write quizzes with two z’s.
Here is the short version:
- Singular: quiz
- Plural: quizzes
- Verb forms: quiz, quizzes, quizzed, quizzing
The same spelling works in every English-speaking country. There is no regional version of “quizes” that is considered correct.
The Origin of Quizes or Quizzes
The exact origin of the word “quiz” is unclear, and dictionaries say so openly. It appeared in English in the late 1700s, first meaning an odd or eccentric person, and later a hoax or a teasing question. By the 1800s, it had moved toward the meaning we use today, which is a short test or a set of questions.
You may have heard a popular story about a Dublin theater manager who made up the word on a bet. Language historians treat that tale as a legend because no solid evidence supports it. What we do know is that the word has been spelled with a z for a long time, and its plural has always followed the same pattern.
Why Quizzes Has Two Z’s
English has a common spelling rule for short words. When a one-syllable word ends in a single vowel followed by a single consonant, the final consonant is usually doubled before an ending that begins with a vowel. This is why “hop” becomes “hopped” and “run” becomes “running.”
Quiz follows the same pattern. In this word, the letter u works like a consonant sound after the q, so the only real vowel before the final z is i. That makes the ending “vowel plus single consonant,” and the z doubles before adding -es.
Other words with the same pattern include these:
- fez becomes fezzes
- whiz becomes whizzes
- quiz becomes quizzes
Not every word ending in z doubles it. Words like “waltz,” “blitz,” and “topaz” form their plurals differently (“waltzes,” “blitzes,” “topazes”), because they have a consonant before the z or a different stress pattern. This is why the topic of words ending in z plural rules can feel confusing, and why it helps to learn quiz as its own clear example.
British English vs American English Spelling
Some words change between British and American English, such as “color” and “colour” or “center” and “centre.” Quiz is not one of them. Both varieties use quiz for the singular and quizzes for the plural.
For a U.S. audience, this is good news. You do not need to remember a separate rule for quiz spelling in American English. If you write quizzes, you are correct in the United States, the United Kingdom, Canada, and Australia.
One small difference is in how the word is used. In the U.S., a quiz is often a short test in school. In the U.K., a quiz can also mean a trivia game played at a pub or on TV. The spelling stays the same either way.
Which Spelling Should You Use?
Use quizzes whenever you mean more than one quiz. The spelling “quizes” has no accepted use, so you do not need to choose between two valid options. This is a case where one form is simply right.
A quick test can help. If you can replace the word with “tests” or “short tests,” you need the plural, and the plural is quizzes.
Use quizzes for:
- More than one test or set of questions, such as “The teacher gave three quizzes this week.”
- Online learning content, such as “The course includes weekly quizzes.”
- Trivia games or entertainment, such as “We play quizzes every Friday night.”
- The third-person singular verb, such as “She quizzes her students before each lesson.”
The last item surprises some writers. Quizzes can be a plural noun or a verb form, and both use the same spelling.

Common Mistakes with Quizes or Quizzes
The most frequent mistake is writing “quizes” because it looks like a normal plural. Many English nouns just add -es, as in “boxes” or “buses.” Writers apply that habit to quiz and leave out the second z.
Other mistakes show up around the same word:
- Writing “quizs” or “quiz’s” for the plural. An apostrophe shows possession, not a plural.
- Writing “quized” instead of “quizzed” for the past tense.
- Writing “quizing” instead of “quizzing” for the present participle.
The fix for all of these is the same. Remember that the final z doubles whenever an ending is added. These are among the common spelling mistakes in English that spell checkers catch quickly, but they still slip through in handwritten notes and fast messages.

Emails are a place where spelling mistakes happen fast. Here are a few correct sentences:

News
News writing is formal and clear, so spelling must be accurate. Examples include:

Plural of quiz Oxford Dictionary
Major dictionaries, including Oxford and Merriam-Webster, list “quizzes” as the plural of quiz. They do not list “quizes” as a variant or alternate spelling. When a standard dictionary gives only one plural, you can treat that form as the correct one.
If you want to double-check any word, look it up in a reliable dictionary and read the entry for the plural and verb forms. Entries usually show them right after the part of speech, in a short line such as “plural quizzes.” This habit is useful for any word you are unsure about.
Quiz plural and singular
The singular is quiz, and the plural is quizzes. You use the singular when you mean one test and the plural when you mean two or more. This is the quiz plural form in standard English.
Here are a few examples:
- “I have a quiz tomorrow.” (one quiz)
- “I have two quizzes this week.” (more than one)
- “That quiz was harder than the last one.” (one quiz)
- “Those quizzes were easy.” (more than one)
Notice that the verb also changes to match. “This quiz is short” uses “is,” while “These quizzes are short” uses “are.” Matching the verb to the noun is part of using the singular and plural forms correctly.
Quizzes meaning
A quiz is a short test of knowledge, usually made up of a few questions. It can be given in a classroom, in a workplace training session, or just for fun. Quizzes can be written, spoken, or online.
As a noun, quizzes meaning is simple: more than one such test. As a verb, “quizzes” means asks someone questions, as in “He quizzes the new hires on safety rules.” Both meanings share the same spelling, and context tells you which one is meant.
Quizzes join
People often search for “quizzes join” when they want to take part in an online quiz game. In that setting, “join” is a verb, and “quizzes” is the plural noun. For example, “Students can join quizzes using a code from the teacher.”
This phrase also shows a small grammar point. When quizzes is the subject of a sentence, the verb stays in its base form. You would write “Quizzes join the lineup each week,” not “Quizzes joins.” With the singular, you add an s: “The quiz joins the lineup.”
Quized or quizzed
The past tense of the verb quiz is “quizzed,” with two z’s. The same doubling rule applies here as it does in the plural. The final z doubles before the ending -ed, just like “stopped” or “planned.”
Here are the forms to remember:
- Base form: quiz
- Third-person singular: quizzes
- Past tense and past participle: quizzed
- Present participle: quizzing
So “quized” and “quizing” are both incorrect. A correct sentence would be “The teacher quizzed the class on Tuesday.”
