Form and rules
How it works
All/most refer to larger groups; both/either/neither normally refer to two.
Both means the two; either means one or the other; neither means not one and not the other.
Use any in negatives/questions and for unrestricted choice; no + noun and none (of) express zero quantity.
Use of before determiners/pronouns when needed: most of the staff, both of them, none of us.
Placement matters around auxiliaries: They have all arrived; They are both ready.
