What type of amendment combines striking out and inserting words or phrases?

A substitute amendment is used to propose a complete replacement for a specific part of a motion or a proposal, which is evident in its functionality of striking out certain words or phrases and inserting different ones. This type of amendment effectively changes the essence of the original motion by substituting its content rather than merely altering portions of it.

The use of a substitute amendment is particularly important during debates, as it allows for a more thorough revision of ideas and can introduce entirely new concepts or frameworks into the discussion, enhancing the overall decision-making process. By allowing members to propose comprehensive changes, it encourages a collaborative environment where diverse opinions are taken into account, leading to more thoughtful outcomes.

Other options, while they may pertain to amendments, do not adequately describe the dual action of both striking out and inserting content into the proposal. Consequently, the distinction of the substitute amendment as addressing both elements (removal and addition) highlights its unique function in procedural contexts.
