phosphorus

phosphorus: [17] Etymologically, phosphorus means ‘bringing light’. The word comes via Latin phōsphorus from Greek phōsphóros, a compound adjective formed from phōs ‘light’ and the suffix -phóros ‘carrying’ (a relative of English bear), which was used as an epithet for the planet Venus as it appears at dawn. It was also applied to any substance that that glowed, and in the mid 17th century it was taken up as the term for the newly isolated element phosphorus, which catches fire when exposed to the air. Phosphate [18] was borrowed from French phosphat, a derivative of phosphore ‘phosphorus’.

phosphorus (n.)

"substance or organism that shines of itself," 1640s, from Latin phosphorus "light-bringing," also "the morning star" (a sense attested in English from 1620), from Greek Phosphoros "morning star," literally "torchbearer," from phos "light," contraction of phaos "light, daylight" (related to phainein "to show, to bring to light;" see phantasm) + phoros "bearer," from pherein "to carry" (see infer).

As the name of a non-metallic chemical element, it is recorded from 1680, originally one among several substances so called; the word used exclusively of the element from c. 1750. It was discovered in 1669 by Henning Brand, merchant and alchemist of Hamburg, who derived it from urine. Lavoisier demonstrated it was an element in 1777. According to Flood, "It is the first element whose discoverer is known."
