Categorization is like labeling things. We can make groups and put things in those groups according to what makes sense. For example, if we have a box of apples, oranges, and bananas, we might categorize the items into two groups: fruits and vegetables. The apples and oranges would go into the group called "fruits," and the bananas would go into the group called "vegetables." This way, we can identify what is in the box by looking at the categories.
