φωσφόρος

Forms

φωσφόρος (phōsphóros) m or f (neuter φωσφόρον); second declension^[1] Poetic φαοσφόρος (phaosphóros) and φαεσφόρος (phaesphóros).^[2][3]

Etymology

A compound from Ancient Greek φῶς (phôs) + -φόρος (-phóros), “light” and “bearing”, the second part from φέρω (phérō, “to carry”).^[1][4][5] Poetry also has the forms φαοσφόρος (phaosphóros) and φαεσφόρος (phaesphóros), built on the uncontracted noun φάος (pháos); Πάπυρος explains φωσφόρος as contracted from the first of these.^[2][6]

Earliest recorded meaning

Euripides, in the 5th century BC, is the first to use it: in the Ion dawn is “light-bringing”, and in the Helen it is an epithet of Hecate.^[2][7][8]

Semantic evolution

The adjective described what brings or gives light: dawn, torches, the eyes in Plato's Timaeus and the Cyclops' eyeballs in Euripides.^[2][4] As an epithet of torch-bearing goddesses it belonged above all to Hecate and Artemis, and in Aristophanes' Frogs the initiates call Iacchus the light-bringing star of the night rites.^[2][9] As a noun, with or without ἀστήρ (astḗr), ὁ φωσφόρος was the morning star, the planet Venus, the Greek equivalent of Latin lucifer.^[2][5][10] Galen records it as the name of an eye-salve.^[2]

The Second Letter of Peter uses it once, as a figure for the day-star rising in believers' hearts.^[11][12][13] Byzantine writers used it for the sun, the Suda glossing it as the one that makes the light rise, and Psellus for the moon.^[14][15]

Latin phosphorus meant “light-bringing” and “the morning star”; from the 17th century it named substances that shine of themselves, and then the chemical element.^[16] Modern Greek φωσφόρος (fosfóros) is the element, a word taken from French phosphore and so a loan returning to Greek.^[17][18][6]
