The Latin word for light is lux. In Latin, lux is used to denote light in both a literal and metaphorical sense. It can refer to physical light, such as sunlight or artificial light, as well as abstract concepts like enlightenment or clarity.
For example, in the phrase lux in tenebris, it means ‘light in darkness,’ symbolizing hope or knowledge in difficult times. The word lux has also influenced many modern languages, including English, where it appears in words like ‘luminous’ and ‘illuminate.’
