lobby Cultural  

1. A group whose members share certain goals and work to bring about the passage, modification, or defeat of laws that affect these goals. Lobbies (also called interest groups or pressure groups) can be long-standing (such as minority groups struggling to have their civil rights guaranteed) or ad hoc (such as a community threatened by proposed construction of a nuclear power plant). Lobbies may use grassroots methods, such as local rallies and campaigns, to build support for their cause and often employ professional lobbyists, who testify before congressional committees and approach policymakers in all government branches. Powerful lobbies, such as the AFL-CIO and the American Legion, with millions of members, have succeeded in establishing influence in Washington, D.C.

Etymology

Origin of lobby

1545–55; < Medieval Latin lobia, laubia covered way < Old High German *laubia (later lauba ) arbor, derivative of laub leaf

Explanation

A lobby is a large waiting room or reception area. If you're waiting for an appointment in a lobby, maybe you'll get lucky and find a good magazine or even a peppermint candy. You'll find a lot of people hanging around in a lobby — which is basically what it’s there for. A lobby is where you meet your friend at the hotel or catch the elevator for your interview. The idea of the "political lobby group" came from the large entrance halls of the legislature, where people hung around trying to influence the lawmakers. So the next time your class tries to lobby your teacher for extra credit, he can thank the halls of Congress.
