Frequently Asked Questions

Do "Mx" and "my" mean the same thing in a sentence?
No - they are not even the same part of speech. "Mx" is a noun and "my" a determiner, so a sentence built for one is usually ungrammatical with the other.
In ordinary English text, does "Mx" or "my" show up more?
"my" is the more common of the two: it sits at frequency rank #27 in our English list, against #18,635 for "Mx". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
