Antimatroid
Antimatroids are like a game where we have a bunch of toys and we want to sort them out in a special way. But we can't just sort them any way we want, there are rules we have to follow.
One of the rules is that we can't have any toys that are too similar to each other in the same group. For example, if we have two dolls that look almost exactly the same, we can't put them in the same group.
Another rule is that we can't have any group that has too many toys in it. We can only have a certain number of toys in each group.
So an antimatroid is just a special way of sorting toys out that follows these rules. We can think of it like a game where we're trying to be really careful and precise about how we organize our toys.
