Frequently Asked Questions

Do "one" and "oui" mean the same thing in a sentence?
No - they are not even the same part of speech. "one" is a noun and "oui" an adverb, so a sentence built for one is usually ungrammatical with the other.
In ordinary French text, does "one" or "oui" show up more?
"oui" is the more common of the two: it sits at frequency rank #132 in our French list, against #2,436 for "one". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
