Frequently Asked Questions

Can "N2" and "non" be used interchangeably?

No - they are not even the same part of speech. "N2" is a name and "non" an adverb, so a sentence built for one is usually ungrammatical with the other.

"non" is the more common of the two: it sits at frequency rank #82 in our French list, against #34,636 for "N2". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
