Um.

So I am refreshing my German using Duolingo -- 146 day streak woo -- and one of the words today was Ernst, meaning seriousness. One of the sentences I encountered three times with this word; the first time was the “refrigerator magnet” sort of thing where you have a list of words that you pick out the correctly translated sentence from.

The German sentence was “Im Ernst” -- and there is no punctuation in Duo but the vocal inflection was as a question. Literally, this translates to “in the seriousness”

The only possible English translation from the provided words, and apparently the default translation for that sentence, is “No kidding”.

Seriously, Duo? Seriously?
