Etymology: Ancient Greeks had a word for the morning star, "phōsphoros," meaning "light-bringer," from "phôs" (light) and "-phoros" (bearing). Latin borrowed it as "phōsphorus" for the planet Venus, and it was later applied to the element phosphorus, which glows faintly in the dark, a property that gave the name its sense of "light-bearing" in a new setting. Phosphate comes from the French "phosphate," built on "phosphoric acid" plus the chemical suffix "-ate," which marks a salt or ester. In other words, the word describes a family of salts derived from phosphoric acid, and the name records the element's glow in the chemical vocabulary of the period.
