>>11278616It's Kurzgesagt, not your misspelling of it.
Kurzgesagt is a German channel and "kurzgesagt" in German roughly translates to "in a nutshell" in English which is why their YouTube name is now "Kurzgesagt - In a Nutshell"
BUT the cool thing is that the literal meaning of "kurzgesagt" is basically "shortly said". Because "kurz" in German means short, like "kurzes Haar" means "short hair", and "gesagt" in German is the past-tense version of "sagen", which means "to say". And obviously to say something shortly, or briefly, is to describe it in a nutshell, which is why the closest equivalent phrase in English is "in a nutshell".
So yeah, the literal translation of "kurzgesagt" is "shortly said" (or maybe more accurately "short said" but obviously "shortly said" conveys the meaning better).
