I have long wondered whether the word “none” is plural (“None of us are”) or singular (“None of us is”).

Well, it suddenly occurred to me that the Internet might know, so I asked Oxford, and here is what it told me:

Some traditionalists maintain that none can only take a singular verb (as in “none of them is coming tonight” rather than “none of them are coming tonight”). However, none is descended from Old English nan meaning “not one”, and has been used for around a thousand years with either a singular or a plural verb, depending on the context and the emphasis needed.

I love the Internet dearly.
