Nouns and capital letters
Bitte mit Welcher? (Please with which one?) - these sentences are according to durolingo. Durolingo says welcher in this instance must be a capital as all nouns are capitalized. Why is "which one" a noun here, any more than say "it" or "that" would be?
You're right and Duolingo is wrong. "Welcher" is not a noun and it is not capitalised (unless it is the first word in a sentence).
Thank you for answering. After posting this I found yet another similar sentence which requires a capital letter according to duolingo. So....I am thinking there must be some logic to their doing this????? Apparently in specific situations they treat some adverbs, adjectives as nouns depending on their use.....??????? Just guessing.?
In the sentence you quoted, the spelling is just wrong. Adjectives, on the other hand, sometimes get an article and are then treated as a noun, e.g. "Ich wünsche dir alles Gute" (I wish you all the best). In this sentence, "Gute" is treated as a noun. Similarly, verbs can be turned into nouns and are then capitalised: "Das Schwimmen macht Spaß" (Swimming is fun). Have you got any specific examples?
