The definition of a caucus is a private meeting of leaders before a more general, open meeting.
Although the exact origin of the word is still unknown, it is often said that caucus comes from “cau´-cau-as´u”—the Algonquin word for "counsel." The term probably introduced into political usage in the United States through the Democratic Party in New York known as Tammany Hall, an organization which commonly adopted Native American terms to suit their own purposes. However, there are also some people who attribute the term to the Latin word “caucus” that means “drinking vessel.” These people say the phrase was first used to describe political activity by the Caucus Club of Boston.
In the United States, the term caucus is often used in reference to the procedure some states use to select their presidential nominees.
Another, although less common, definition of caucus is as a description of a sub-grouping of elected government officials who plan meetings to affect public policy. These groups often share a common interest, such as a shared ethnicity or political faction.(noun)
Caucus is defined as to hold or take part in a private meeting before a more general, open meeting.(verb)
