Frequently Asked Questions

Do "tho" and "too" mean the same thing in a sentence?

No - they are not even the same part of speech. "tho" is an article and "too" an adverb, so a sentence built for one is usually ungrammatical with the other.

In ordinary English text, does "tho" or "too" show up more?

"too" is the more common of the two: it sits at frequency rank #121 in our English list, against #3,588 for "tho". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
