Frequently Asked Questions

Can "o" and "of" be used interchangeably?
No - they are not even the same part of speech. "o" is a symbol and "of" a preposition, so a sentence built for one is usually ungrammatical with the other.
Which is more common, "o" or "of"?
"o" is the more common of the two: it sits at frequency rank #28 in our Spanish list, against #692 for "of". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
