Frequently Asked Questions

Is swapping "an" for "ay" ever safe?
No - they are not even the same part of speech. "an" is an article and "ay" an intj, so a sentence built for one is usually ungrammatical with the other.
In ordinary English text, does "an" or "ay" show up more?
"an" is the more common of the two: it sits at frequency rank #30 in our English list, against #12,729 for "ay". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
