(some) when to use different forms

Hello I am going over lesson 8.7 In the Section (some) you have, di and its various forms, qualche, and alcuni. My question is how do I know when to use each variation of some. Sorry the answer is probably in the lesson but I am not getting it. The masc /fem/plural I get. Tom

Hi Tom Qualche is used when it is followed by a singular noun (ending in -o/a) But expresses plurality. Which is probably the most common. Alcuni or alcune is only used in the plural, hence- notes, letters. Not a note or a letter. Un po' di (a bit of) is often used for food items. I think most are interchangeable except alcuni alcune because they are plural. I hope this helps. Grahame

Hi Tom, "some" in Italian can be translated in different ways. "qualche" and "alcuni" can be used when meaning "few". "qualche" is followed by singular noun and "alcuni" by plural nouns. I hope this helps.
