Pronunciation

  • Classical: [ˈmyː.ri.as][1]
  • Ecclesiastical: [ˈmiː.ri.as][1]

Forms

mȳrias f (genitive mȳriadis); third declension[1] The accusative plural is myriadas, as in Greek.[2][3] Medieval writers also spell it mirias.[3][4]

Etymology

It is borrowed from Ancient Greek μυριάς (muriás, “ten thousand”),[1][5][2] from μυρίος (muríos, “countless”).[5][6] Its further origin is not certainly explained.[5]

Earliest recorded meaning

Georges cites it from the Latin translation of Irenaeus and Bede's work on numbers,[2] of the 8th century.[5]

Semantic evolution

It meant the number ten thousand, or a myriad, in Christian and medieval Latin.[7][8][4] Medieval writers used it for a countless number: of people, of money or of years,[9] and of the hosts of heaven, the countless angels.[4][3] Humanist translators of Plutarch used it for the Greek ten thousand.[10][4] English took myriad in the 1550s, from French and directly from the Late Latin word.[6]

Timeline

  • 1st third of 8th century AD – Bede uses it in his work on numbers.[2][5]
  • 1550s – English borrows myriad, partly from it.[6]
