A category is a group of items, concepts, or entities that share common characteristics and are treated as belonging together. It is used to organize information, objects, or ideas so they can be more easily understood, compared, and managed. Categories can be formal, such as scientific classifications, or informal, like everyday groupings people use in conversation. In many fields, including linguistics, logic, and data science, categories help structure knowledge, define boundaries, and support analysis. They play a key role in how humans think, learn, and communicate about the world.
