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.

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 acceptable English. There is no reason to avoid it.

In fact, from the 16th to the 19th century, the English noun was used to mean "ten thousand", primarily in translations from Greek or Latin, or in reference to the Greek numerical system.

The noun is used in both the singular (a myriad of voices) and in the plural (the myriads of voices; the voices of myriads).

Since myriad seems to be used in the picture more as an adjective instead of a noun, would it be more accurate for the character in the cartoon to be saying: "I have a myriad of doubts about the legality of our business contract!!" or "I have myriads of doubts about the legality of our business contract!!"?
