The Eastern Caribbean Currency Union (ECCU) is one of the world's four regional currency unions. The union is a development of the Organization of Eastern Caribbean States, in which the member countries agree to share the same currency, the Eastern Caribbean dollar (EC dollar).

The ECCU is composed of the nations of Antigua and Barbuda, Dominica, Grenada, St. Kitts and Nevis, St. Lucia, and St. Vincent and the Grenadines and the British territories of Anguilla and Montserrat.

Free people of color (French: gens de couleur libres [ʒɑ̃ də kulœʁ libʁ]; Spanish: gente de color libre) were primarily people of mixed African, European, and Native American descent in the Americas who were not enslaved. However, the term also applied to people born free who were primarily of black African descent with little mixture.

There were distinct groups of free people of color in the French colonies, including Louisiana and in settlements on Caribbean islands, such as Saint-Domingue (Haiti), St. Lucia, Dominica, Guadeloupe, and Martinique. In these territories and major cities, particularly New Orleans, and those cities held by the Spanish, a substantial third class of primarily mixed-race, free people developed.

A volcanic plug, also called a volcanic neck or lava neck, is a volcanic object created when magma hardens within a vent on an active volcano. When present, a plug can cause an extreme build-up of high gas pressure if rising volatile-charged magma is trapped beneath it, and this can sometimes lead to an explosive eruption. In a plinian eruption the plug is destroyed and ash is ejected.

Glacial erosion can lead to exposure of the plug on one side, while a long slope of material remains on the opposite side. Such landforms are called crag and tail. If a plug is preserved, erosion may remove the surrounding rock while the erosion-resistant plug remains, producing a distinctive upstanding landform.
