In English, the "ten thousand" sense of "myriad" mostly appears in references to Ancient Greece, such as the following from Thirwall's History of Greece: "4000 men from Peloponnesus had fought at Thermopylae with 300 myriads." More often, however, English speakers use "myriad" in the broad sense -- both as a singular noun ("a myriad of tiny particles") and a plural noun ("myriads of tiny particles"). "Myriad" can also serve as an adjective meaning "innumerable" ("myriad particles"). "Myriad" comes from Greek "myrias," which in turn comes from "myrioi" ("countless" or "ten thousand"). A relative of "myriad" is "myriapod," which descends in part from the Greek word for "foot." A myriapod is a creature with many feet -- a centipede or millipede, that is.
