Frequently Asked Questions

Do "if" and "ii" mean the same thing in a sentence?
No - they are not even the same part of speech. "if" is a noun and "ii" an adverb, so a sentence built for one is usually ungrammatical with the other.
In ordinary French text, does "if" or "ii" show up more?
"ii" is the more common of the two: it sits at frequency rank #627 in our French list, against #7,069 for "if". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
