What does "bicameral legislature" mean?

A bicameral legislature refers to a legislative body that consists of two separate chambers or houses. This system is common in various governmental structures, including the United States Congress, which is divided into the House of Representatives and the Senate. The bicameral system allows for more comprehensive representation and checks and balances within the legislative process, as each chamber has its own unique responsibilities, powers, and methods of operation.

This setup contrasts with a unicameral legislature, which comprises only one chamber. The two-chamber arrangement encourages deliberation and can enhance accountability, as legislation must pass through both houses, allowing for more extensive debate, discussion, and amendment of proposed laws before they can become law.
