Chamber of DeputiesThe chamber of deputies is the lower house in many bicameral legislatures and the sole house in some unicameral legislatures. Historically, French Chamber of Deputies was the lower house of the French Parliament during the Bourbon Restoration, the July Monarchy, and the French Third Republic; the name is still informally used for the National Assembly under the nation's current Fifth Republic.
Lower houseA lower house is one of two chambers of a bicameral legislature, the other chamber being the upper house. Despite its official position "below" the upper house, in many legislatures worldwide, the lower house has come to wield more power or otherwise exert significant political influence. The lower house, typically, is the larger of the two chambers, meaning its members are more numerous. In comparison with the upper house, lower houses frequently display certain characteristics (though they vary per jurisdiction).
SenateA senate is a deliberative assembly, often the upper house or chamber of a bicameral legislature. The name comes from the ancient Roman Senate (Latin: Senatus), so-called as an assembly of the senior (Latin: senex meaning "the elder" or "old man") and therefore considered wiser and more experienced members of the society or ruling class. However the Roman Senate was not the ancestor or predecessor of modern parliamentarism in any sense, because the Roman senate was not a de jure legislative body.
Member of parliamentA member of parliament (MP) is the representative in parliament of the people who live in their electoral district. In many countries with bicameral parliaments, this term refers only to members of the lower house since upper house members often have a different title. The terms congressman/congresswoman or deputy are equivalent terms used in other jurisdictions. The term parliamentarian is also sometimes used for members of parliament, but this may also be used to refer to unelected government officials with specific roles in a parliament and other expert advisers on parliamentary procedure such as the Senate parliamentarian in the United States.
LegislatureA legislature is an assembly with the authority to make laws for a political entity such as a country or city. They are often contrasted with the executive and judicial powers of government. Laws enacted by legislatures are usually known as primary legislation. In addition, legislatures may observe and steer governing actions, with authority to amend the budget involved. The members of a legislature are called legislators.
