The correct spelling is quizzes with double “z.” The spelling quizes is incorrect in standard English.
The word quiz follows a spelling rule where the final consonant doubles before adding endings like -es or -ed. Because “quiz” ends with a single vowel followed by “z,” the letter doubles.
Examples:
Singular: Quiz
Plural: Quizzes
Past tense: Quizzed
Incorrect forms:
Quizes
Quized
Correct examples:
The teacher gave three quizzes this week.
Our class completed online quizzes for practice.
She quizzed the students before the test.
So if you are wondering can you spell quizzes with one z, the answer is no. English spelling rules require the double “z.”
If you have ever typed quizzes vs quizes into Google, you are not alone. Many writers, students, bloggers, and teachers wonder which spelling is correct. At first glance, both forms may look reasonable. The word “quiz” is short, so adding an “s” for the plural seems simple. Yet English spelling rules often behave in surprising ways.
This confusion usually appears when people write school content, online quizzes, or educational posts. Some also ask related questions such as is it quizzes or quizes, is it quized or quizzed, or why the plural of quiz becomes quizzes instead of something simpler.
The truth is that only one spelling follows correct English grammar rules. Understanding why helps you avoid common mistakes in writing, exams, emails, and social media. In this guide, you will learn the rule, the origin, and the correct usage so you never mix them up again.
The Origin of quizzes vs quizes
The word quiz has an interesting history. It appeared in English during the late eighteenth century. Some language historians believe it started as slang meaning a strange person or a joke. Over time, the meaning changed to describe a short test of knowledge.
When teachers began using the word in schools, the plural form naturally developed. English grammar rules already had a pattern for words ending with z. These words often double the final letter before adding endings.
Because of this rule, the plural of quiz became quizzes instead of quizes.
This rule also explains why people ask why is the plural of quiz quizzes. It follows the same pattern used in many other English words.
Examples include:
Buzz → Buzzes
Fizz → Fizzes
Quiz → Quizzes
The plural of quiz Oxford Dictionary confirms the spelling “quizzes.” Dictionaries, grammar guides, and academic writing all use this form.
The incorrect spelling quizes usually happens when people assume that adding “s” is enough. English, however, often requires doubling consonants to keep pronunciation clear.
British English vs American English Spelling
Many spelling differences exist between British and American English. Words like colour and color or theatre and theater are famous examples.
However, quizzes vs quizes is not one of those differences. Both British and American English use quizzes as the correct plural spelling.
This means writers in the United States, the United Kingdom, Canada, Australia, and other English speaking regions follow the same rule.
Examples in both styles:
American English
Our class has weekly quizzes.
British English
Students completed several quizzes before the exam.
Even international education platforms, apps like Quizizz, and learning websites use the spelling quizzes.
