Types refer to categories or classifications that help organize and understand various subjects. They can be based on shared characteristics, functions, or purposes. For example, in biology, species are types of living organisms that share similar traits, while in literature, genres categorize works based on style and content. In everyday life, types can also refer to different forms of products or services. For instance, vehicles can be classified into types such as cars, trucks, and motorcycles, each serving distinct needs. Understanding types allows for better communication and decision-making in various fields.
