Frequently Asked Questions

Can "something" and "something's" be used interchangeably?
No - they are not even the same part of speech. "something" is a pronoun and "something's" a contraction, so a sentence built for one is usually ungrammatical with the other.
Which is more common, "something" or "something's"?
"something" is the more common of the two: it sits at frequency rank #152 in our English list, against #17,494 for "something's". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
