Frequently Asked Questions

Is swapping "ia" for "ins" ever safe?

No - they are not even the same part of speech. "ia" is a verb and "ins" a preposition, so a sentence built for one is usually ungrammatical with the other.

In ordinary Portuguese text, does "ia" or "ins" show up more?

"ia" is the more common of the two: it sits at frequency rank #600 in our Portuguese list, against #27,900 for "ins". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
