Frequently Asked Questions

Is swapping "pu" for "Py" ever safe?

No - they are not even the same part of speech. "pu" is a verb and "Py" a name, so a sentence built for one is usually ungrammatical with the other.

In ordinary French text, does "pu" or "Py" show up more?

"pu" is the more common of the two: it sits at frequency rank #307 in our French list, against #35,663 for "Py". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
