Difference between a proposition and a bill?

A proposition is a proposed idea or plan put forward for consideration, often in a political or legislative context, and can refer to initiatives or amendments that may be voted on by the public or a governing body. A bill, on the other hand, is a formal written proposal for new legislation or an amendment to existing laws that is introduced in a legislative body, such as a parliament or congress, and must undergo a specific process of debate, revision, and approval before becoming law. In essence, while both are proposals, a bill is a specific type of proposition that follows a structured legislative procedure.
