The word "illuminant" has its origin in the Latin term "illuminans", which is the present participle of the verb "illuminare". "Illuminare" means "to light up", "to illuminate", or "to make clear". The Latin word is derived from the prefix "il-" (meaning "in" or "on") and "luminare" (meaning "to shine" or "to light"), which itself comes from "lumen" (meaning "light"). Over time, the term "illuminant" was adopted into English, with the same basic meaning of something that illuminates or provides light.
