Congress is an alphabet soup of obscure abbreviations and terms that make it difficult for anyone other than insiders to follow what happens in the Capitol. This explainer provides a glossary that is intended to help the public unpack some of the most commonly-used terms on Capitol Hill, in the media, and among Hill-watchers. Recognizing these terms is helpful for communicating with Congress effectively and understanding the legislative process. This glossary is not exhaustive and does not delve into every facet of every term. It is intended only to provide readers with a basic understanding of the terms’ most common uses.
