Forms
μῡρῐᾰ́ς (mūriás) f (genitive μῡρῐᾰ́δος); third declension[1] Boeotian μουριάς.[2]
Etymology
It is derived from μυρίος (muríos, “countless; ten thousand”) with the suffix -άς.[1][3][4] μυρίος has no etymology, according to Beekes.[5] Wiktionary mentions links with a root for “damp”, as of the countless waves, or with μύρμηξ (múrmēx, “ant”), and Etymonline a root for “abundant”.[5][1][4]
Earliest recorded meaning
Simonides and Herodotus use it for the number ten thousand.[6][2]
Semantic evolution
It was used in counting men, money (drachmas), and measures of corn.[6][2] From Euripides on it also meant a countless multitude, and as an adjective “innumerable”.[6][2] Archimedes and Diophantus used it as a unit of large numbers, with the “second myriad” for ten thousand times ten thousand.[6][3]
The Septuagint and the New Testament use it for ten thousand and for countless hosts, especially of angels, with the apocalyptic “myriads of myriads” in Revelation.[7][3] Through Late Latin myrias and French it gave English myriad (1550s).[4]
