What is the difference in meaning/usage between "nişte" and "câteva"?
Thanks. Does this mean that "câteva" can only be used with countable things (chairs, people, etc.), but "niște" can be used with both countable and uncountable things (chairs, people, water, soup, air...)? I want to make sure I understand correctly. (At least that's the difference between "some" and "a few" in English.)
You are correct. It's also part of the indefinite article.
Un băiat - Niște băieți.
You can say "niște aer", "niște apă" (some air, some water) etc.
