Frequently Asked Questions

Do "s" and "Sif" mean the same thing in a sentence?

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

Frequency check: "s" vs "Sif" - which ranks higher?

"s" is the more common of the two: it sits at frequency rank #142 in our English list, against #49,636 for "Sif". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
