A mayor is a leader of a city or town, but there are many other words that can be used to describe this type of position. One term that can be used is "governor", which typically refers to the leader of a state. Another word that can be used is "prefect", which is a term used in some countries to describe the leader of a local government organization. "Burgomaster" is another synonym for mayor, which is used in some parts of Europe. "Municipal chief executive" is a more formal term that can also be used to describe a mayor's position. Regardless of the title used, the role of a mayor is to govern and serve their city or town.
