Throughout most of its history in Englishmyriad was used as a noun, as ina myriad of men. In the 9th centuryit began to be used as an adjective,as inmyriad men; this usage became so well entrenchedthat many people came to consider it as the only correct possibility.In fact, both uses have not only ample precedent in English but also etymological justification from Greek,in as much as the Greek wordmurias from which myriad derives could be used as either a noun or an adjective.Both uses may be considered equally acceptable,as in Samuel Taylor Coleridge`s.Myriad myriads of lives..
在英文中，myriad 的大部分歷史一直被用作名詞， 如在數以萬計的男子 。 在9世紀，它開始被用作形容詞，如在myriad men 中， 這種用法很快就被人們認可了，而且還認為它是唯一的正確用法。事實上，這兩種用法不僅在英文中而且在希臘語的語源糾正中都有許多先例，因為源於myriad 的希臘語單詞 munias ， 既可用作名詞也可用作形容詞。兩種用法同樣被接受，如塞繆爾·泰勒爾里奇的.Myriad myriad of lives.
