Why does "neu" become "Neues" after "etwas"?
I found this sentence in a German children's book: >Jeden Tag entdeckt Katrin etwas Neues. Neues is a noun here? How can that be? I'd think that 'new' was an adjective. As a noun, I found Neue in the dictionary, and then I found other cases of 'etwas Neues' So what is happening here? Is it, in fact, "Neue" that's been changed for some reason?
