English spelling can be tricky, especially when it comes to plural forms of short words. One of the most common spelling doubts people search for online is “quizzes or quizes.” You may have seen both spellings used in blogs, social media posts, or even learning platforms, which naturally creates confusion.
This keyword is popular because quizzes are everywhere today: online learning, job assessments, school exams, marketing campaigns, and social media polls. When writers need the plural form of quiz, they often hesitate. Should it follow simple plural rules and become quizes, or does it need something extra?
The confusion mainly comes from English doubling rules. Some words double the final consonant before adding -es, while others do not. Learners, non-native speakers, students, teachers, and even professional writers frequently stop to check which spelling is correct.
This article solves that confusion clearly and completely. You’ll get a quick answer, the history behind the word, British vs American spelling rules, common mistakes, real-life examples, usage advice by audience, and even Google Trends insights. By the end, you’ll know exactly which spelling to use and why without second-guessing yourself again.
Quizzes or Quizes – Quick Answer
✔️ The correct spelling is quizzes.
❌ Quizes is incorrect and considered a spelling mistake.
Examples:
- She created three online quizzes for her students.
- The app includes daily brain-training quizzes.
The word quiz forms its plural by doubling the final “z” and adding “-es.” English spelling rules require this doubling to maintain pronunciation clarity.
The Origin of Quizzes or Quizes
The word quiz has an unusual and debated history. It first appeared in English in the late 18th century. Some historians believe it came from slang used by students, while others think it may have originated as a made-up word that gained popularity.
What matters for spelling is how English handles short words ending in -z. Over time, English developed a convention: when a one-syllable word ends in a single vowel followed by z, the z is doubled before adding endings like -es or -ed.
That is why:
- quiz → quizzes
- buzz → buzzes
- fizz → fizzes
The spelling quizes ignores this historical rule, which is why it never became standard.
British English vs American English Spelling
Good news: there is no difference between British and American English for this word.
Both British and American English follow the same rule and accept quizzes as the only correct plural form.

| Variant | British English | American English | Correct? |
