Pronunciation

  • Classical: [ˈdae̯.moːn][1]
  • Ecclesiastical: [ˈdɛː.mon][1]

Forms

daemōn m (genitive daemonis); third declension[1] Also spelt dēmōn in curse tablets; the accusative plural is often daemonas.[2][3]

Etymology

It is borrowed from Ancient Greek δαίμων (daímōn, “god, divine power, spirit”).[4][1][5] Köbler, after Pokorny, connects the Greek word with Proto-Indo-European *dā- (“to divide”), and Etymonline gives a stem Proto-Indo-European *dai-mon- (“divider, provider (of fortunes)”).[5][6] Ancient writers explained it otherwise: Augustine says the demons were named from knowledge, and Servius explains the word as “those who know everything”.[2]

Earliest recorded meaning

Varro writes the Greek κακὸς δαίμων in his Menippean satires; in Latin the word appears from Apuleius,[2] who uses it in On the God of Socrates for a spirit between gods and men, a genius.[4][3][5]

Semantic evolution

For Apuleius and the Platonists a daemon was a spirit that went between gods and men, like the Roman genius or lar.[4][7][3] In astrology Firmicus Maternus gives the name bonus daemōn (Greek ἀγαθοδαίμων) to one of the twelve places of the sky.[7] In Christian writers, following the Greek of the Bible translations,[6] the word means an evil spirit, a devil, and also a pagan god or idol;[8][9][3] correptus daemone is “possessed by the devil”.[3] Medieval Latin keeps these senses and has plant names such as fuga daemonum for St John's wort.[10][11]
