Etymology
The word 'phosphorescent' is a modern scientific term built from classical elements. Its first part, 'phosphor', originates from Greek mythology as the name for the planet Venus, the "Light-Bringer". The suffix '-escent', borrowed from Latin, denotes a state of becoming or emitting. The term was formed in the 18th century to describe the property of certain substances to emit a lingering glow after being exposed to light, logically combining the concept of "light" with the process of "emitting". Thus, the literal "becoming a light-bringer" evolved into the precise technical meaning of emitting cold light.
