Etymology

From diēs (day) and Mercuriī, genitive of Mercurius (Mercury). Latin calque of Ancient Greek ἡμέρα (hēméra, day) Ἑρμοῦ (Hermoû) ("of Hermes"). The association of the seven week days with the seven classical planets is first attested in the Anthologiarum by Vettius Valens, ca. AD 170 and was known to Cassius Dio by the early 3rd century.

Pronunciation

  • (Classical Latin) IPA(key): [ˈdi.eːs ˈmɛr.kʊ.riː]
  • (modern Italianate Ecclesiastical) IPA(key): [ˈd̪iː.es ˈmɛr.ku.ri]
  • The pronunciation Mercurī instead of regularized Mercuriī is the one regularly expected for BCE Classical Latin, but it is also reflected by Romance centuries later, and in light of this was likely in general use for naming this weekday.
  • (Regularized) IPA(key): [ˈdi.eːs mɛrˈkʊ.ri.iː]
  • (Regularized) IPA(key): [ˈd̪iː.es merˈkuː.ri.i]
