ORIGIN mid 16th cent. (sense 2 of the noun) : via late Latin from Greek murias, muriad-, from murioi‘10,000.’

USAGE Myriad is derived from a Greek noun and adjective meaning ‘ten thousand’. It was first used in English as a noun in reference to a great but indefinite number. The adjectival sense of ‘countless, innumerable’ appeared much later. In modern English, use of myriad as a noun and adjective are equally standard and correct, despite the fact that some traditionalists consider the adjective as the only acceptable use of the word.
