"None Is" or "None Are"?
It's a myth that "none" can only be singular. Check out the examples.
"None" can be singular or plural, but many people believe it can only be singular.
"None" Is Singular
"None" can mean roughly “not one” and be followed by a singular verb. It also takes a singular verb when followed by a mass noun:
None of the water is polluted.
"None" Is Plural
Sometimes "none" means roughly “not any”;or your sentence has a sense of plurality. In such cases, "none" can take a plural verb, and;it often sounds more natural.
I talked to the boys, and none of them are coming to the party.
What Should You Do?
You may be chided by the uninformed when you follow "none" with a plural verb, but don’t be afraid to do so if your sentence calls for it.
