Frequently Asked Questions

Is swapping "ten" for "to" ever safe?

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

Frequency check: "ten" vs "to" - which ranks higher?

"to" is the more common of the two: it sits at frequency rank #2 in our English list, against #959 for "ten". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
