Frequently Asked Questions

Is swapping "I'd" for "in" ever safe?

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

In ordinary Portuguese text, does "I'd" or "in" show up more?

"in" is the more common of the two: it sits at frequency rank #269 in our Portuguese list, against #33,016 for "I'd". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
