Pronunciation

  • 5th-century BC Attic: /blás.pʰɛː.mos/[1]
  • 4th-century AD Koine: /ˈβlas.ɸi.mos/[1]
  • 10th-century Byzantine: /ˈvlas.fi.mos/[1]

Forms

βλᾰ́σφημος (blásphēmos) m or f (neuter βλᾰ́σφημον); second declension[1]

Etymology

Its second element is from Ancient Greek φήμη (phḗmē, “utterance, report”); the first is uncertain, and words such as βλάβος (blábos, “harm”) and μέλεος (méleos, “vain”) have been proposed.[2] Beekes notes that the verb βλασφημέω (blasphēméō) and the noun βλασφημία (blasphēmíā) seem older than the adjective, which is rare and late, a relation he compares with that of ἀνδραγαθία (andragathíā) to the phrase “good man”.[2]

Wiktionary traces it to Proto-Hellenic *mləspʰāmos, with a first element from Proto-Indo-European *(s)mel- (“to deceive”), a link Beekes does not accept.[1][2]

Byzantine etymologists derived it from βλάβη (blábē, “harm”) and the noun for utterance, or from βάλλω (bállō, “to throw”), as one who “throws” insults.[3]

Earliest recorded meaning

It first appears in the 4th-century orators: Isocrates and Demosthenes use it of words that are slanderous or abusive.[4][5][6]

Semantic evolution

Aristotle applies it to a person, the evil-speaking poet Archilochus, and Plutarch and Lucian use it with a genitive for words that slander someone or something.[5][7][6] In the ancient language it described words of ill omen.[8][7]

The Septuagint (2 Maccabees, Wisdom) and the New Testament give it the religious sense of speaking against God, and use it as a noun for a blasphemer.[9][10][7] It was borrowed as Latin blasphemus.[1] The modern βλάσφημος (vlásfimos) is a learned word continuing the medieval adjective.[8][11]

  • Modern Greek – The word is a learned survival, βλάσφημος (vlásfimos).[8]
