What is titular definition?

A titular definition is a definition that is based on the title, name or designation of the person, place or thing being described. In other words, it refers to the specific term or title used to describe a person, place or thing rather than its actual identity or nature. For example, a person may hold the titular position of president but may not have any real authority or power. Similarly, a building may be given a titular name or title based on its function or historical significance but may not actually be used for that purpose in modern times. The term "titular" is often used to describe such formal or ceremonial titles or positions, which may not carry any substantial responsibilities or duties.
