Is myriad a noun?: Usage Guide

Recent criticism of the use of myriad as a noun, both in the plural form myriads and in the phrase a myriad of, seems to reflect a mistaken belief that the word was originally and is still properly only an adjective. As the entries here show, however, the noun is in fact the older form, dating to the 16th century. The noun myriad has appeared in the works of such writers as Milton (plural myriads) and Thoreau (a myriad of), and it continues to occur frequently in reputable English. There is no reason to avoid it.

Did you know?

You don’t need ten thousand justifications to use myriad as a noun, only one: with more than 400 years of usage history behind it, the noun myriad, as in the phrase “a myriad of,” is a well-established and respectable member of the English language. Still, we understand that “myriad of” raises the hackles of myriad folks who were taught at one point or another that myriad is only to be used as an adjective, and that phrases like “a myriad of emailers vexed about myriad” should be shunned in favor of “myriad emailers vexed about myriad.” Now, to each their own lexical peeves and pleasures, but let it be known that myriad entered the English language in the mid-1500s as a noun, and since its introduction has been used in the senses of “ten thousand,” “a set of ten thousand,” “an immense or indefinitely large number,” and “a great multitude”; furthermore, it has appeared in the works of such writers as Milton, Thoreau, Twain, and DuBois—no slouches when it comes to wielding words. Myriad the adjective is about 200 years younger, but both continue to enjoy wide use today.
