luminaria

Luminaria is a fairly recent addition to English; early usage dates from the 1930s, about the time that the Mexican Christmas custom started to gain popularity among Anglo-Americans. In some parts of the U.S., particularly New Mexico, these festive lanterns are also called farolitos, which means "little lanterns" in Spanish. We borrowed luminaria from Spanish, but the word has been around with exactly the same spelling since the days of Late Latin. The term ultimately traces to the classical Latin luminare, meaning "window," and to lumen, meaning "light." It is related to other light-bearing words such as luminary, illuminate, and phillumenist (a fancy name for someone who collects matchbooks).
