Frequently Asked Questions

Do "lui" and "luis" mean the same thing in a sentence?
No - they are not even the same part of speech. "lui" is a pronoun and "luis" a verb, so a sentence built for one is usually ungrammatical with the other.
In ordinary French text, does "lui" or "luis" show up more?
"lui" is the more common of the two: it sits at frequency rank #68 in our French list, against #6,627 for "luis". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
