Which motion can interrupt a speaker?

The motion that can interrupt a speaker is the point of order. This motion allows a member to challenge a procedure or raise an issue regarding the rules while another member is speaking. It is designed to maintain adherence to parliamentary procedure and ensure that the meeting runs smoothly according to established rules. By allowing interruption, it helps to address potential violations or clarify confusion immediately.

Other motions like previous question, adjourn, and amend typically do not have the ability to interrupt a speaker. Previous questions relate to ending the debate on a motion, adjourn concerns closing the meeting, and amend focuses on altering the wording of a motion currently under consideration—all of these require the current speaker to finish before they can be formally introduced.
