A bicameral legislature refers to a legislative body that is divided into two separate chambers or houses. While the term bicameral is the most common synonym for this type of legislative system, there are other synonyms that could be used instead. For example, a "dual chamber" or "two-tiered" legislature is another way of describing a bicameral setup. A "two-house" or "two-room" legislature could also be used to convey the same meaning. Additionally, a "separate house" or "divided parliament" could be used in some contexts to describe a bicameral legislative system. Regardless of the synonym used, the key characteristic of a bicameral legislature is that it is made up of two separate and distinct chambers.
