What parliamentary ability is employed to add or make changes to a motion?

The ability to add or make changes to a motion in parliamentary procedure is called an amendment. This process allows members to modify the original motion to clarify, enhance, or refine it before the assembly votes on it. Amendments can be used to introduce new ideas or adjustments that address concerns raised during discussions. This flexibility ensures that the motion can be tailored to better suit the needs and viewpoints of the group, promoting more effective decision-making.

In contrast, nullifying a motion involves completely dismissing it, which does not alter it but eliminates it. Postponing a motion temporarily delays its consideration to a later time, without changing the content of the motion itself. Withdrawing a motion means that the person who made it chooses to retract it entirely, rather than modify it. Each of these options has distinct purposes in parliamentary procedure, but only an amendment specifically focuses on making modifications to an existing motion.
