How are theories classified?

Theories are classified based on various criteria, including their scope, purpose, and field of study. For example, they can be categorized as descriptive, explanatory, or predictive theories, depending on whether they aim to describe phenomena, explain relationships, or forecast future events. Additionally, theories can be classified as grand theories, which provide broad frameworks, or middle-range theories, which focus on specific aspects of a phenomenon. Disciplines such as natural sciences, Social Sciences, and humanities may also influence the categorization of theories.
