Frequently Asked Questions

Is swapping "ib" for "ii" ever safe?
No - they are not even the same part of speech. "ib" is an abbrev and "ii" a verb, so a sentence built for one is usually ungrammatical with the other.
Frequency check: "ib" vs "ii" - which ranks higher?
"ii" is the more common of the two: it sits at frequency rank #968 in our Spanish list, against #24,896 for "ib". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
