Frequently Asked Questions

Can "I" and "y" be used interchangeably?
No. They are pronounced the same ([ˈi]), which is exactly why they get swapped in writing, but the dictionary meanings above are different, and pronunciation is no guide here.
Which is more common, "I" or "y"?
"y" is the more common of the two: it sits at frequency rank #6 in our Spanish list, against #360 for "I". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
