moderator

MAH-duh-ray-ter/ˈmɑːdəreɪtər/

A person who guides a discussion.

The moderator makes sure everyone has a chance to speak.

Etymology

A moderator is literally someone who regulates. The Latin sense of manager or director connects naturally with the later role of presiding over a discussion and keeping its proceedings within bounds.
