You’ve typed “quizes” into a sentence, paused, and thought wait, does that look right? You’re not alone. This is one of the most common spelling slips in English, and it trips up students, bloggers, and even fluent writers.
The correct spelling is “quizzes,” with a double “z.” The mix-up happens because quiz ends in a single consonant, and most people forget that English doubles that final letter before adding “-es.” Once you know the rule, you’ll never second-guess it again.
Quizes or Quizzes – Quick Answer
The correct plural of quiz is quizzes, not quizes. English doubles the final consonant before adding “-es” whenever a short word ends in a single vowel followed by a single consonant, and quiz fits that pattern exactly.
Here’s the rule in one line: quiz becomes quizzes, never quizes.
A couple of quick examples make it stick:
- Correct: She scored well on both quizzes this week.
- Incorrect: She scored well on both quizes this week.
The Origin of Quizzes
Where did this odd little word even come from? Quiz entered English in the late 1700s, and its exact origin is genuinely uncertain dictionaries like Merriam-Webster list it as “origin unknown,” which is rare for such a common word. Some language historians link it to old slang used for teasing or questioning someone playfully.
By the 1800s, quiz had settled into its modern meaning: a short test of knowledge. Newspapers picked it up as a verb too “police quiz suspect” is a headline you’ll still see in British papers today, using quiz to mean “question.”
As the word spread through schools and, later, online learning platforms, its plural form followed standard English spelling rules. That’s how quiz became quizzes and stayed that way.
British English vs American English Spelling
Does it matter if you’re writing for a UK or US audience? Not here. Quiz and quizzes are spelled exactly the same in both British and American English a rare case where regional spelling differences simply don’t apply.
| Form | British English | American English |
| Singular | quiz | quiz |
| Plural | quizzes | quizzes |
| Incorrect | quizes | quizes |
Whether you’re writing for London or Los Angeles, the rule doesn’t change: quizzes is the only correct plural, everywhere.
Which Spelling Should You Use?
Simple answer: always use quizzes. There’s no context, audience, or writing style where quizes becomes acceptable not in casual texts, not in academic papers, not anywhere.
Use Quizzes For:
- Academic writing and school assignments
- Blog posts and articles
- Online courses and e-learning platforms
- Social media captions
- Business and training materials
If you remember nothing else from this article, remember this: quiz always becomes quizzes.
Common Mistakes with Quizes or Quizzes
Why do so many people get this wrong? Usually, it’s autopilot they apply the basic “-s” plural rule without thinking about the doubling requirement. Here are the most common slip-ups, corrected:
- Incorrect: We had three quizes this week. Correct: We had three quizzes this week.
- Incorrect: The teacher graded all the quizes. Correct: The teacher graded all the quizzes.
- Incorrect: Online quizes are popular on social media. Correct: Online quizzes are popular on social media.
Notice the pattern? Every mistake comes from forgetting to double the “z” before adding “-es.”
Quizzes in Everyday Examples
Seeing a word used in context makes the correct spelling stick better than any rule alone. Here’s how quizzes shows up across different types of writing.
“Please complete the weekly quizzes before Friday’s deadline.”
News
“Online learning platforms now use short quizzes to test student progress.”
Social Media
“Just finished all my course quizzes feeling accomplished!”
Formal Writing
“Students completed a series of quizzes throughout the semester.”
Education Platforms
“Interactive quizzes help learners retain key concepts more effectively.”
Quized or Quizzed? Getting the Verb Form Right
Quiz isn’t just a noun it’s also a verb, and that trips people up too. When you’re talking about the act of questioning someone, the correct past tense is quizzed, not quized, and the correct present participle is quizzing, not quizing.
The same doubling rule applies here. Because quiz ends in a single vowel plus a single consonant, you double that final “z” before adding “-ed” or “-ing.” So:
- Correct: The teacher quizzed the class on vocabulary.
- Incorrect: The teacher quized the class on vocabulary.
- Correct: She’s quizzing her students right now.
- Incorrect: She’s quizing her students right now.
One rule, two forms noun and verb both doubled the same way.
