What is the national legislative body of a country typically called?

The term "Congress" is specifically used in the context of the United States as the national legislative body. It is a bicameral institution, consisting of two chambers: the House of Representatives and the Senate. This unique nomenclature sets it apart from other countries, which may have their own terms for similar legislative bodies.

While "Parliament" is often used to describe the national legislative bodies in other countries, such as the United Kingdom, and "Senate" and "Assembly" can refer to various forms of legislative bodies in different jurisdictions, the term "Congress" is distinctively associated with the legislative structure of the United States. Thus, in the context of national legislative bodies, "Congress" accurately describes the U.S. Congress and reflects its status as the law-making authority at the national level.
