phosphorus
UK: ˈfɒsfərəs | US: ˈfɑːsfərəs
n. a highly reactive, luminescent chemical element (symbol P) essential for life
n. (archaic) the morning star (Venus) or any luminous substance
Derived from Greek "phōsphoros" (φωσφόρος), combining "phōs" (light) + "phoros" (bearer). The name originally referred to Venus as the "light-bringer" at dawn. In 1669, German alchemist Hennig Brand isolated the element from urine, noting its glowing property—linking it to the ancient term. The "-us" suffix Latinizes the Greek ending.
