Not any; not one; no part or amount of something. It can refer to people, things, or amounts.
From Old English “nān,” from “ne” (not) + “ān” (one), literally “not one.” Related to German “nein” (no) and “kein” (none).
In older English, “none” could be followed by either a singular or plural verb, and even today both “none is” and “none are” can be correct depending on meaning. It quietly hides the idea of “not even one” inside a single short word.
