Classification and categorization both involve sorting things into groups based on shared characteristics, and the words are often used interchangeably. Classification tends to suggest a more formal or scientific system with defined rules, while categorization can be looser and more everyday. In science, classification usually refers to established systems like the ranking of living things.

Classification is the act or system of grouping things by shared characteristics, often creating named categories, while sorting is simply arranging items into an order or into groups. Classification implies a defined scheme of classes, whereas sorting can be as simple as separating by size or colour. Sorting is often a step within classification.

Classification is widely used in biology, library science, data science, and law, wherever things must be sorted into groups by shared characteristics. In biology it organizes living things, and in libraries it arranges books by subject. The word signals an organized system rather than a one-off grouping.
