What does quention mean?

"Quention" is not a recognized word in the English language. It's likely a misspelling of "question."

If you meant "question", it means:

* To ask for information or clarification: "I have a question about the homework."

* To express doubt or uncertainty: "I question whether this plan will work."

* To challenge or investigate something: "The police questioned the suspect."

Please let me know if you meant something else.
