How to use the Quantity partitives Alcuno, Alcuna, Alcuni , Alcune and Qualche
Alcuno, Alcuna, Alcuni , Alcune and Qualche all mean "a few, some." However, usage depends on several factors. One factor addresses countable and non-countable quantities. Something countable, such as coins can have a number in front of it. Something uncountable, such as sugar, normally does not have a number in front of it.
Qualche is an adjective used ONLY with countable nouns. Despite its plural meaning, it always is used with singular masculine and feminine nouns. For example: Every day, I write some letters = Ogni giorno scrivo qualche lettera.
Alcuno, in it masculine and feminine singular and plural forms, can be used as either a pronoun OR as an adjective with plural nouns. Its feminine or masculine singular forms - alcuno or alcuna- are ONLY used in negative sentences. For example, a DL Lesson uses the following: Lui non risponde ad alcuna domanda. = He does not respond to any questions.
Alcuni/alcune can be used, in the plural ONLY with countable nouns instead of qualche. For example: There are a few women here. = Ci sono alcune donne qui.(used as an adjective). There are a few. = Ci sono alcune. (used as a pronoun).
Eccellente! I have it written on a bright orange postit next to meglio and migliore!
But you can say "Voglio delle mele" which means "I want some apples" so how does that work out? Like should I said "Voglio delle mele" or "Voglio qualche mele"?
Buon giorno Jeffrey! Your examples with the apples are both correct. Di+a definite article can be used for both countable (e.g., apples) or non-countable nouns; while qualche is used only for countable nouns. Keep in mind that when asking a question involving 'some" or 'any' use di+the definite article or qualche and not any form of alcuno. Ciao!
