None Is vs. None Are
Because none means “not one” and “not any,” some believe that the word should always be treated as singular and followed by a singular verb. However, since the ninth century none has been used with both singular and plural verbs. When it is used to mean “not any,” the plural verb is generally used: We dove for coins but none were found. When it is intended to mean “not one,” it is followed by a singular verb: In spite of all the prophecies, none has come true. Currently, none is usually seen with a plural verb. So if you can’t remember the subtle differences, you can use either a plural or a singular verb and probably no one will even notice—or care.
