Frequently Asked Questions

Can "Y" and "yes" be used interchangeably?
No - they are not even the same part of speech. "Y" is a character and "yes" a noun, so a sentence built for one is usually ungrammatical with the other.
In ordinary French text, does "Y" or "yes" show up more?
"Y" is the more common of the two: it sits at frequency rank #43 in our French list, against #9,417 for "yes". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
