Which word refers to someone who previously held a position or title?

The term that refers to someone who previously held a position or title is "predecessor." This word is commonly used in various contexts, such as in business or politics, to describe an individual who has already occupied a particular role before another person takes over that position. For example, if a new CEO is appointed, the person who held that position prior is known as the predecessor. Using this term helps to clarify the lineage of leadership or authority within an organization, highlighting the transfer of responsibilities.

In comparison, the other terms do not convey the same meaning. A successor refers to a person who follows after, taking over from someone else. A contender is someone who competes for a position but does not imply any prior holding of that position. A colleague is simply a peer or coworker and does not suggest any hierarchical relationship regarding past or present titles.
