Frequently Asked Questions

Is swapping "abo" for "an" ever safe?

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

In ordinary English text, does "abo" or "an" show up more?

"an" is the more common of the two: it sits at frequency rank #30 in our English list, against #38,261 for "abo". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
