Frequently Asked Questions

Is swapping "shui" for "si" ever safe?
No - they are not even the same part of speech. "shui" is a typographic variant and "si" a conjunction, so a sentence built for one is usually ungrammatical with the other.
Frequency check: "shui" vs "si" - which ranks higher?
"si" is the more common of the two: it sits at frequency rank #46 in our French list, against #34,752 for "shui". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
