Etymology: The stem comes from Latin "lumen," meaning "light," and it is one of the oldest English-related light words. "Lumen" traces back to an Indo-European root, "*leuk-," that also gave English "light" and Latin "lux." The Latin word was a close relative of "lux," so "light" and "lumen" are distant cousins that came into English by different routes. Standalone "lumin" is rare as a noun. It works mainly as a combining form in words like "luminous," "luminary," and "illuminate," which entered English from Latin and Old French in the late Middle Ages. "Luminary," for example, originally meant a source of light, such as the sun or moon, before it came to mean a person who shines in a field. "Illuminate" is built from "in-" plus "lumen," and its sense of lighting up a space carried over to lighting up a manuscript with decoration and then to enlightening a mind.
