Questions & Answers about Некоторые студенты не пришли.
Why does this sentence use Некоторые instead of a кое- pronoun from this lesson, like кое-какие?
Некоторые simply means a general "some" or "a portion of." If you used Кое-какие студенты or Кое-кто из студентов, it would carry a secretive tone meaning "a certain few": it implies the speaker knows exactly who didn't come but is deliberately choosing not to name them. For a standard factual statement, некоторые is the natural choice.
Why is the perfective verb пришли used here with не, rather than the imperfective приходили?
Negating a perfective verb focuses on a single, specific failure to achieve a result: they were expected for this specific class or event, but they did not arrive. Using the imperfective не приходили would mean they didn't use to come at all (habitual) or would simply state the fact of their absence over a broader, less specific timeframe.
Quick refresher: how does the prefix при- in пришли change the meaning compared to пошли or ушли?
The prefix при- focuses on arrival at a destination, so пришли means "came" or "arrived." In contrast, пошли focuses on the start of a trip ("set off" or "started walking"), and ушли focuses on departure ("left" or "went away").
Does Некоторые change endings like a noun or an adjective?
