What it means: A form containing a set of questions.

In a sentence: The teacher gave us a questionnaire to learn about our favorite animals.

The part people get wrong

Watch for double n, and an unstressed vowel that is hard to hear.

Same family: question, questioner, questioning, questionable, survey. If you can spell one, the shared part carries to the others.

Where it comes from: “Questionnaire” comes from French, formed from “question” plus the suffix “-naire,” originally used for people or things connected with a list (as in “millionaire”). It entered English in the 19th century, and its French-style ending is one reason many people find it tricky to spell.
