Frequently Asked Questions

Can "it" and "iu" be used interchangeably?

No - they are not even the same part of speech. "it" is a pronoun and "iu" an abbrev, so a sentence built for one is usually ungrammatical with the other.

In ordinary Portuguese text, does "it" or "iu" show up more?

"it" is the more common of the two: it sits at frequency rank #1,934 in our Portuguese list, against #42,065 for "iu". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
