“Quizzes” is the correct spelling of the plural of quiz. “Quizes” is incorrect and should not be used in English.
Why is the plural of “quiz” quizzes?
We need to add “es” to the word “quiz” because the word ends in a “z”.
When we have a vowel-consonant-e construction in English, we usually pronounce the “e” sound as a long sound. When there is a double consonant that should result in a short vowel sound.
Because the “e” in “quizzes” has a short vowel sound, we need to double the consonant”z”.
We hold many online quizzes every year.
