GERMANENESS: One of the most important differences between the House and Senate is the House rule that all amendments must be germane (relevant or related) to the bill under consideration. In the Senate, this is only true for general appropriations and budget bills.
FILIBUSTER: Talking a proposal to death or to get a compromise is only allowed in the Senate. Cloture is the process by which such unlimited debate can be ended. When invoked by roll call vote -- three-fifths of those present and voting -- it limits each senator to one hour of debate. Other delaying tactics such as requiring time-consuming recorded votes or raising complex questions about legislative procedures ("points of order") can be used in either the House or Senate. :)
