Frequently Asked Questions

Do "tema" and "tha" mean the same thing in a sentence?
No - they are not even the same part of speech. "tema" is a noun and "tha" a verb, so a sentence built for one is usually ungrammatical with the other.
In ordinary Portuguese text, does "tema" or "tha" show up more?
"tema" is the more common of the two: it sits at frequency rank #840 in our Portuguese list, against #38,931 for "tha". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
