Frequently Asked Questions

Is swapping "Theo" for "two" ever safe?
No - they are not even the same part of speech. "Theo" is a name and "two" a num, so a sentence built for one is usually ungrammatical with the other.
Frequency check: "Theo" vs "two" - which ranks higher?
"two" is the more common of the two: it sits at frequency rank #86 in our English list, against #11,987 for "Theo". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
