Frequently Asked Questions

Do "and" and "au" mean the same thing in a sentence?

No - they are not even the same part of speech. "and" is a conjunction and "au" an article, so a sentence built for one is usually ungrammatical with the other.

In ordinary French text, does "and" or "au" show up more?

"au" is the more common of the two: it sits at frequency rank #24 in our French list, against #837 for "and". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
