Quizzes is the correct plural form of quiz. The spelling quizes is incorrect in standard English because words ending in a single vowel + consonant usually double the final consonant before adding -es.
A few years ago, while editing content for an education website, I noticed the same mistake appearing again and again. Writers, students, and even business professionals kept typing “quizes” instead of “quizzes.”
At first, it seems like a tiny spelling issue. After all, both words look similar. Yet only one is accepted in standard English.
This confusion happens because English spelling rules are not always simple. Many people know that plural nouns often end with -s or -es, but they are unsure when a letter should be doubled. That uncertainty leads to mistakes in emails, school assignments, blog posts, and social media content.
If you have ever paused and wondered whether to write quizzes or quizes, you are not alone.
By the end of this guide, you will know the correct spelling, understand why it works that way, see real-world examples, avoid common mistakes, and feel confident every time you use the word.
Let’s clear up the confusion once and for all.
Quizzes or Quizes – Quick Answer
The correct spelling is quizzes.
The word quiz becomes quizzes in its plural form because the final z is doubled before adding -es.
Examples
✅ I created three quizzes for my students.
✅ The website offers hundreds of fun quizzes.
❌ I created three quizes for my students.
❌ The website offers hundreds of fun quizes.
Whenever you need the plural of quiz, use quizzes.
The Origin / Background of Quizzes or Quizes
The word quiz first appeared in English during the late 1700s. Its exact origin is debated, but it quickly became a popular term for a short test or a set of questions.
The confusion starts when people try to make the word plural.
Most English words simply add -s:
- Book → Books
- Car → Cars
- Student → Students
Some words add -es:
- Box → Boxes
- Wish → Wishes
- Class → Classes
The word quiz follows a special spelling pattern. Because it ends in a single z, English doubles the z before adding -es.
That creates:
Quiz → Quizzes
Over time, this spelling became the accepted standard in dictionaries, schools, publishing, and professional writing.
