Today I learned that "Löschen" doesn't always mean deletion or putting out a fire. For some reason, it also means to unload freight. I mean, come on, how does that make sense?
German: grüner Star, grauer Star
This blew my mind. Grüner Star is glaucoma, grauerStar is cataracts. Why? I have no idea! Is glaucoma green? According to this history of ophthalmology ... maybe.
