A man who uses a great many words to express his meaning is like a bad marksman who instead of aiming a single stone at an object takes up a handful and throws at it in hopes he may hit. Samuel Johnson. Words, like glasses, obscure everything they do not make clear. Before using a fine word, make a place for it.
A unicameral legislature consists of only one chamber, or legislative house. When it began, the U.S. had a unicameral legislature, but then soon changed to a bicameral legislature, a two-house Congress made up of the Senate and the House of Representatives.
Before the United States Constitution was written, the unicameral legislature was not effective enough to handle all of the nation's affairs. Once the Constitution was adopted, the United States moved to a bicameral legislature, a two-house Congress made up of the Senate and the House of Representatives. Bicameral legislatures are generally the structure used within U.S. state governments as well.
