What happens if a motion is not seconded during a meeting?

When a motion is not seconded during a meeting, it fails to proceed to discussion because the lack of a second indicates that no other member supports the motion. In parliamentary procedure, a second is necessary to demonstrate that at least one other person believes the matter deserves consideration. Without that support, the motion does not move forward and is effectively dismissed without being debated or voted upon. This principle reinforces the idea that motions should have sufficient backing from members before they are considered by the group.
