Frequently Asked Questions

Can "to" and "two" be used interchangeably?

No - they are not even the same part of speech. "to" is a particle and "two" a num, so a sentence built for one is usually ungrammatical with the other.

Which is more common, "to" or "two"?

"to" is the more common of the two: it sits at frequency rank #2 in our English list, against #86 for "two". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
