Frequently Asked Questions

Is swapping "sent" for "syn" ever safe?
No - they are not even the same part of speech. "sent" is a verb and "syn" a noun, so a sentence built for one is usually ungrammatical with the other.
In ordinary French text, does "sent" or "syn" show up more?
"sent" is the more common of the two: it sits at frequency rank #1,575 in our French list, against #39,569 for "syn". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
