Okay kiddo, so cyclic negation is like when you say the opposite of something over and over again, but it keeps coming back to the same thing.
Imagine you have an apple in front of you. If you say "this apple is not red," that's a form of negation because you're saying the opposite of what it is. But if you keep saying the negation over and over again, like "this apple is not red, this apple is not green, this apple is not purple," eventually you'll end up back where you started because you've covered all the possible colors.
In math and logic, cyclic negation is often used in a similar way to show that certain statements or concepts can't actually be negated. It's like saying "not not X" - you can keep negating X all you want, but it still ends up being the same thing in the end.
It can get a bit tricky and confusing, but the basic idea is that cyclic negation is a way of showing that some things are just fundamentally true and can't be negated, no matter how hard you try.
