Nouns have capital letters, so why is it telling me to use them in other words
grrr why is it telling me to use capital letters for Unsere, when according to my german friend that's wrong! it should be unsere! so why?
Perhaps because DuoLingo is not perfect yet, but still frustrating. Btw, I could think up some contexts, where Unsere is used as a noun. In that case it gets capitalized. I assume, the phrase you are referring to used "unsere" as possessive pronoun?
