Which type of motion is primarily used to introduce a new item for consideration?

The main motion is the appropriate type of motion used to introduce a new item for consideration. This is the foundational motion in parliamentary procedure, which allows members of an assembly to bring forward a new proposal or idea for discussion and decision. By presenting a main motion, members can formally initiate debate on the subject, ensuring that the agenda is followed and that everyone has the opportunity to discuss the item at hand.

Using a main motion is essential in structured meetings, as it provides a clear framework for members to propose actions or changes, allowing for effective organization and management of the meeting's agenda. In contrast, the other types of motions—subsidiary, incidental, and privileged—serve different purposes. Subsidiary motions help to modify or dispose of a main motion, incidental motions are related to the procedures of the meeting itself, and privileged motions address urgent matters that require immediate attention but do not introduce new business.
