Input: Consider Input: Question: Background We have a motivational poster in our office that says: None of us is as smart as all of us. I think that it's grammatically incorrect, and here is my reasoning: All of the tigers have spots. All of us are here. None of us are dead yet. The three examples all sound correct when using the plural "are", rather than "is". Question Unfortunately, some of my coworkers disagree with me. They believe that the quote is correct when it uses the word "is". So my question is this: Is the motivational quote grammatically correct or should it say "all"? 
Answer: "None" is just short for "no one". None is not plural. It's not singular either, but it's even less plural. So "No one of us IS smarter..." I mean, I sure am not, but this is open and shut.

Output: no
