Frequently Asked Questions

Is swapping "diary" for "of" ever safe?

No - they are not even the same part of speech. "diary" is a noun and "of" a preposition, so a sentence built for one is usually ungrammatical with the other.

In ordinary German text, does "diary" or "of" show up more?

"of" is the more common of the two: it sits at frequency rank #324 in our German list, against #45,854 for "diary". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
