Pronunciation

  • IPA (4th-century AD Koine): /ˈɸos/[1]
  • IPA (10th-century Byzantine): /ˈfos/[1]

Forms

φῶς (phôs) n (genitive φωτός); third declension[1]

Etymology

It is the Attic contraction of φάος (pháos) “light”,[2][3][4] which is inherited from Proto-Hellenic *pʰáwos,[1] from Proto-Indo-European *bʰeh₂- (“to shine”).[2][1] Beekes and Frisk trace the whole group to a thematic aorist *φαϝεῖν, seen only in the Homeric φάε (pháe) “appeared, shone” and a few other rare forms; the Pamphylian spelling φάβος (phábos) keeps the old /w/.[2][3]

After the contraction the old s-stem (genitive φάους) was remade as a t-stem, genitive φωτός (phōtós), on the model of χρώς (khrṓs) and ἔρως (érōs); epic φόως (phóōs) is the same contracted form with its vowel “stretched” for metre.[2][3][1] Beekes and Frisk find it unnecessary to assume a separate inherited form φῶς.[2][3] Wiktionary compares Latin iubar (“radiance”), Sanskrit भास् (bhā́s, “light”) and Old English basu (“purple”).[1] Related within Greek are φαίνω (phaínō) and φαεινός (phaeinós) “shining”.[2][1]

Earliest recorded meaning

Homer has only the uncontracted φάος and epic φόως, never φῶς.[4] They mean the light of day and of the sun, which stands for life itself (“to leave the light of the sun” is to die), the light of a lamp, a dear person (“you have come, Telemachus, sweet light”), help or deliverance in battle, and in the plural the eyes.[5]

Semantic evolution

The tragedians use φάος or φῶς as the metre requires, and in prose φῶς is the only form of the nominative and accusative.[4] “To see the light” meant to be alive, and “into the light” meant into existence or into public view.[6][7]

Hellenistic Greek built new words on the stem φωτ-: φωτεινός (phōteinós) “luminous” (from Xenophon on) and φωτίζω (phōtízō) “to give light, enlighten”, which Christians also used of baptism.[2][7] In the Septuagint light appears at Genesis 1:3 and becomes a common metaphor; in the New Testament the word is used of God and of spiritual illumination, the light of truth.[8][6][9] Christian writers applied it to God, to Christ, to the Trinity and to angels and saints, as in the Creed's “light from light”.[10]

It survives as Modern Greek φως (fos).[11] Triantafyllidis notes that some of its learned senses are modelled on French lumière.[11] Modern Greek φωτιά (fotiá) “fire” is a reshaped form of it.[1]

Timeline

  • Homer – φάος and φόως for daylight and life.[4][5]
  • 5th century BC – Sophocles and Euripides speak of the “light of heaven” and the “light of the upper air”.[4][12]
  • 5th–4th century BC – Plato writes of the light of the sun, and Xenophon has the derivative φωτεινός.[4][2][12]
  • 2nd century BC – Polybius uses ἅμα τῷ φωτί, “at daybreak”.[4][12]
  • 1st century AD – the New Testament uses it of God and spiritual light.[6][9]
  • Modern Greek – φως, with senses partly modelled on French lumière.[11]

Usage notes

The lexicographers distinguish φῶς “light” from the acute-accented φώς (phṓs) “man”, a poetic word of uncertain origin; an old proposal links it with the root for “shine”, which Beekes finds semantically implausible.[13][14][2]
