Spelling
Questionaire or questionnaire?
Questionnaire is the right spelling. Questionaire is a common misspelling of it.
QUESTIONAIRE has one N where QUESTIONNAIRE has two.
Why people write QUESTIONAIRE
Double letters are not heard when the word is said, so it is easy to write only one. The doubling usually comes from how the word was built: a prefix that ends in the same letter as the root (ac + commodate), or a final consonant doubled before an ending (begin, beginning).
Double N, from French: questio-NN-aire.
How often QUESTIONNAIRE is misspelled
In the web pages Google counted for its trillion-word corpus (Peter Norvig's word counts), QUESTIONAIRE appears 26 times for every 1,000 QUESTIONNAIRE, about once for every 38 correct uses.
