Frequently Asked Questions

Do "thin" and "ti" mean the same thing in a sentence?
No - they are not even the same part of speech. "thin" is an adjective and "ti" a pronoun, so a sentence built for one is usually ungrammatical with the other.
In ordinary Portuguese text, does "thin" or "ti" show up more?
"ti" is the more common of the two: it sits at frequency rank #779 in our Portuguese list, against #34,948 for "thin". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
