Frequently Asked Questions

Do "thin" and "this" mean the same thing in a sentence?
No - they are not even the same part of speech. "thin" is an adjective and "this" a pronoun, so a sentence built for one is usually ungrammatical with the other.
In ordinary German text, does "thin" or "this" show up more?
"this" is the more common of the two: it sits at frequency rank #2,559 in our German list, against #45,623 for "thin". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
