In Destination B2 book, these definitions are given for quantifiers little and a little:
little: uncountable nouns, means 'not much'
a little: uncountable nouns, means 'some'
Now, given the following sentence:
We've only got ______ milk left so get some when you go shopping.
We've only got ______ milk left so get some when you go shopping.
I choose little as I thought the talker meant that there's not much milk left so they needed some to be bought. But the correct answer is a little.
Can someone explain why is that so?
