In Major League Baseball, a "perfect game" is a

classic double negative.similar question OG13 SC13.

Precisely. In this sentence, the phrase "nothing else" is a double negative --- there are instances in which double negatives can be correct, but here is a clear grammatical error. The perfect game should is a game in which the team surrenders NOT a hit, NOT a walk, and NOT anything else --- that one "not" at the beginning of the parallel sequence applies equally to each term.
Does this make sense?


Don't you mean OG13 SC21? SC13 ain't got no negatives at all.

Hi mikemcgarry,

Could you explain why it's not true with "and"?

Hi,
when any single item out of the given things IS enoughfor some cause, we will use OR..
when we require all, we will use AND..
Here even one item in th egiven list is sufficient, so we should OR..
I hope I understood your Q correctly

Hi chetan2u,

Thank you so much for your reply. I am not good at grammar, so my question seems akward

Back to the question, when I read the question, I do not determine whether it requires "all" criteria or each of them.

Could you make it clear? Thank you.

Dear oanhnguyen1116

I'm happy to respond. Think about it this way.

The construction "A, B, and C" means one and only one thing: a set with all three of those items included, {A, B, C}.

Because in math & logic, the word "or" is always the inclusive OR, the construction "A, B, or C" includes seven different cases:
1) {A}
2) {B}
3) {C}
4) {A, B}
5) {A, C}
6) (B, C}
7) {A, B, C}

Now in this example, let
A = a walk
B = a hit
C = reaching base some other way
In a "perfect game," none of these things happens. Of the two lists above, which is a complete list of the not allowed things in a "perfect game"? Of course, it's not the single possibility of the "AND" list---it's the seven cases of the "OR" list.

Technically, logically, "not A, B, and C" means that any of three would be allowed individually, that any pair would be fine, and that the only single thing not allowed would be the combination of all three. By contrast, "not A, B, or C" means that no one is allowed and they are not allowed in any combination.

Does all this make sense?
Mike

Now it's clear for me. Thank you so much!
