What term is used for a person who holds influence but is not elected?

The term used for a person who holds influence but is not elected is "informal leader." An informal leader is someone who exercises influence over others through personal attributes, expertise, or charisma rather than through official position or authority granted by an organization or community. They can motivate, inspire, or mobilize others without the necessity of being in a formal leadership role.

This type of leadership is particularly important in various contexts, such as community organizations, grassroots movements, or group collaborations, as informal leaders can effectively shape opinions and behaviors while fostering teamwork and community engagement. Their impact often comes from their ability to connect with individuals on a personal level or through their deep understanding of particular issues, making their influence significant even without an official title.

The other options represent different aspects of leadership or advocacy. A formal leader typically holds a designated position of authority, such as an elected official, while community organizers and advocates may work actively to promote causes, but they might do so in varying capacities, which doesn't necessarily equate to the broader influence of informal leaders.
