Frequently Asked Questions

Can "N" and "nn" be used interchangeably?

No - they are not even the same part of speech. "N" is a character and "nn" an adverb, so a sentence built for one is usually ungrammatical with the other.

In ordinary French text, does "N" or "nn" show up more?

"N" is the more common of the two: it sits at frequency rank #34 in our French list, against #24,303 for "nn". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
