What term describes someone of nominal leadership without real authority?

The term that describes someone who holds a position of nominal leadership without actual authority is "figurehead." A figurehead typically occupies a formal role that suggests leadership or status but lacks the decision-making power and influence that comes with true authority. This term is often used in political or organizational contexts where individuals may represent a group or institution but do not wield the power to enact significant changes or make critical decisions.

For instance, in a corporation, a CEO might be seen as a figurehead if they are primarily performing ceremonial duties while the real management and decision-making are handled by other executives or board members. This distinction highlights the difference between holding a title and possessing the actual power or control associated with that title.
