Frequently Asked Questions

Do "quasi" and "qui" mean the same thing in a sentence?
No - they are not even the same part of speech. "quasi" is a noun and "qui" a pronoun, so a sentence built for one is usually ungrammatical with the other.
In ordinary French text, does "quasi" or "qui" show up more?
"qui" is the more common of the two: it sits at frequency rank #22 in our French list, against #2,332 for "quasi". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
