some
The German word 'einige' is used to express an indefinite quantity or amount, just like the English word 'some'. It can be used with both countable and uncountable nouns. For example, 'Ich habe einige Bücher' (I have some books) and 'Ich möchte einige Milch' (I would like some milk).
I bought some books.
In this sentence, 'einige' is used as an indefinite pronoun to refer to an indefinite quantity of books that is more than one book, but not necessarily a large number.
She needs some time to heal.
Here, 'einige' is used to express an indefinite amount of time. It is a way of saying that she needs time, without stating a specific duration, but implying that it will not be immediate.
We will invite some friends.
In this context, 'einige' refers to an indefinite number of friends. The speaker does not reveal the exact number, but it suggests that it is more than one.
