Frequently Asked Questions

Do "I" and "ins" mean the same thing in a sentence?

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

Which is more common, "I" or "ins"?

"I" is the more common of the two: it sits at frequency rank #286 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.
