Frequently Asked Questions

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

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

In ordinary Spanish text, does "to" or "too" show up more?

"to" is the more common of the two: it sits at frequency rank #1,128 in our Spanish list, against #13,802 for "too". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
