How should a member properly present a simple main motion?

The phrase "I move that..." is the correct way to present a simple main motion in a parliamentary procedure context. This specific wording is standard and widely accepted in formal meetings governed by parliamentary rules, such as those outlined in Robert's Rules of Order.

Using "I move that..." clearly indicates the speaker's intention to propose a specific action or decision to the assembly. This formula helps to maintain clarity and structure in discussions, ensuring that all members understand that a formal proposal is being made. It also sets the stage for further discussion, debate, or amendments if necessary.

The other phrases, while they might convey a similar sentiment, do not adhere to the established terminology used in parliamentary procedure and may lead to confusion or ambiguity regarding the intent to formally propose a motion. By sticking to the correct phrasing, members facilitate orderly conduct and ensure that their proposals are recognized and recorded appropriately.
