Frequently Asked Questions

Do "stay" and "sth" mean the same thing in a sentence?
No - they are not even the same part of speech. "stay" is a verb and "sth" a pronoun, so a sentence built for one is usually ungrammatical with the other.
In ordinary English text, does "stay" or "sth" show up more?
"stay" is the more common of the two: it sits at frequency rank #473 in our English list, against #40,035 for "sth". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
