Answer Question
Qualche e Alcuno
I had to research the words "qualche" and "alcuno" elsewhere to find out how to use them. Fluenz just changed usage without any explanation, so I thought a little clarification might help others. Qualche is an "indefinite adjective" which may mean "some" or "any". Alcuno is a "plural pronoun" which may mean "some" or "a few". So, there is an explanation for the different usages after all. An adjective and a pronoun are quite different in their application, and now it makes more sense to me.
