Origin of myriadGreek m&umacron;rias, m&umacron;riad-, ten thousand, from m&umacron;rios, countless. Usage Note: Throughout most of its history in English myriad was used as a noun, as in a myriad of reasons. In the 1800s, it began to be used in poetry as an adjective, as in myriad dreams. Both usages in English are acceptable, as in Samuel Taylor Coleridge's “Myriad myriads of lives.” This poetic, adjectival use became so well entrenched generally that many people came to consider it as the only correct use. In fact, however, both uses are acceptable today.
Used as an adjective (see below), 'myriad' requires neither an article before it nor a preposition after. Because of this, some consider the usage described in sense 2 above, where 'myriad' acts as part of a nominal (noun) group (that is, "a myriad of animals"), to be tautological.
From French myriade, from Late Latin myriadis (genitive of myrias), from Ancient Greek Î¼Ï…ÏÎ¹Î¬Î´Î¿Ï‚ (myriados), genitive of Î¼Ï…ÏÎ¹Î¬Ï‚ (myrias, “number of 10,000"), from Î¼ÏÏÎ¹Î¿Ï‚ (myrios, “numberless, countless, infinite").
