What Does the Name Lux Mean?
Lux means "light" and comes directly from Latin. The Latin noun lux, with the genitive lucis, was the everyday word for light, particularly daylight, and it belongs to a small family of Latin light words: the verb lucere ("to shine") and the noun lumen ("light," especially a light or lamp).
As a given name in English, Lux is a direct borrowing of the Latin word rather than a development from an older personal name. The same Latin noun also underlies the international unit of illuminance, the lux, and appears in well-known phrases such as fiat lux ("let there be light") and lux et veritas ("light and truth"). The Spanish and Portuguese given name Luz is a relative, since it descends from the same Latin root, but it became a personal name through Christian devotion in the Iberian world and has its own history; it is not the source of English Lux.
Lux Name History & Origins
In classical Latin, lux was a common noun, not part of the small stock of traditional Roman given names, and it carried no fixed personal-name use. Its most durable association is religious: the Latin Bible known as the Vulgate opens the creation account with dixitque Deus: Fiat lux. Et facta est lux ("and God said: Let there be light. And there was light," Genesis 1:3). The word also appears in Christian hymns and titles such as lux mundi ("light of the world"). Other Christian names grew from the same root, including Lucia and its relatives, but those are separate names with their own derivations.
Lux has long been established as a surname in German-speaking Europe and in Luxembourg, where its origin is not settled; explanations that have been offered include a short form of a personal name such as Lukas and a house or place name, and no single derivation is firmly established. As a first name, Lux is chiefly a modern English-language adoption of the Latin word, used for both girls and boys. Recent fictional bearers include Lux Lisbon in Jeffrey Eugenides's novel The Virgin Suicides (1993) and the character Lux in the video game League of Legends (2010); these are notable modern uses of an existing word, not the source of the name.
