To close the meeting when no motion is pending is called?

The term that describes the action of closing a meeting when there is no motion pending is "adjourn." This term is used in parliamentary procedure to officially end a meeting, allowing members to leave and signaling that the session has concluded. Adjournment is often done when there is no further business to discuss, and it is important for maintaining proper order in formal meetings.

The choice of "adjourn" encapsulates the formal process required to end a meeting, distinguishing it from other terms that might imply a more informal or abrupt conclusion. For example, "close" and "end session" could imply various contexts but do not carry the same procedural weight in terms of parliamentary rules. "Terminate" might suggest an ending to something more permanent or in a different context, not specifically related to the formal conclusion of a meeting. Thus, "adjourn" is the most accurate term for this specific action in a meeting setting.
