Quantifier Meets Conditional...

I'm not sure if we have a comprehensive document, if it's not in the quantifier video, but it's important to remember they all bill down to some or most. Not all just means some (although it implies it's more than a small amount usually), while almost any can be reasonably interpreted as a most. The question to ask yourself is does the term imply all or none, in which case it's conditional, and if not, does it strongly imply more than half? If yes it's a most, otherwise it's a some.

And "Some" can technically be at least one, but also "all", right? I remember seeing that in a lecture, but I never really understood how some can be all.

It's technically anything except for none, but I've honestly never seen it used as all. I would remember that some doesn't exclude the possibility of all, but I wouldn't worry about that too much.

Thanks Emil!
