ELI5: Explain Like I'm 5

Opposite category

Imagine you have a set of toys, like toy cars, toy animals, and toy blocks. Now imagine you have a friend who also has a set of toys, but they have different ones like toy dolls, toy robots, and toy puzzles.

Opposite category is all about comparing these two sets of toys. We can create pairs where for every toy in your set, we find a toy in your friend's set that's related in some way. For example, we can compare toy cars and toy dolls because they are both fun to play with.

We can create these pairs by looking at the different ways the toys can connect to each other. Just like how toy cars can connect to each other by racing or stacking, we can connect toy categories by finding similarities that make them go together. This process of finding pairs helps us make sense of the world around us and understand the connections between different things.

In other words, opposite category is a way of comparing two sets of things by looking at how they are different and similar to each other. It helps us understand and categorize different parts of the world.
