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" an adverb, so a sentence built for one is usually ungrammatical with the other.
Which is more common, "y" or "yes"?
"y" is the more common of the two: it sits at frequency rank #6 in our Spanish list, against #14,741 for "yes". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
