What does the term "postpone indefinitely" mean?

The term "postpone indefinitely" refers to a parliamentary procedure that allows members to effectively eliminate a motion from consideration without voting on the merits of that motion. When a motion is postponed indefinitely, it means that the discussion on that motion is halted permanently, and it will not be brought up for a vote or further consideration at any time in the future unless reintroduced by a member.

This process is utilized when members wish to avoid a decision on a particular issue, either because they believe it is not currently relevant, they disagree with it, or they think that further discussion would be unproductive. The key aspect of this term is that it allows for the motion to be set aside without the need for a direct confrontation or vote, thus "killing" the motion in a procedural sense.
