Definition of titular

The word "titular" has its origin in Latin, where "titulus" means "title" or "heading". The Latin term was used to describe the heading or title of a document, such as a literary work or a legal agreement. When brought into English, the word "titular" took on a broader meaning, referring to a title or position that is related to a particular role or office. In the 15th century, the term was commonly used to describe the title of a monarch or nobility, as in "titular king" or "titular duke". Over time, the meaning of the word expanded to encompass other titles, such as a "titular character" in a play or movie, referring to the main or leading role. Today, "titular" is often used to describe a title that is derived from another title, such as a subsidiary title or a secondary title. It can also be used to describe a title that is honorary or titular in nature, rather than actual authority or power.
