About the word "myriad"...

It's an adjective, not a noun.*

Example:
Hillary Clinton has myriad ways of misusing the word myriad.

NOT:
Hillary Clinton has a myriad of ways of misusing the word myriad.

*Before posting this I looked up the word on dictionary.com and discovered that it can be used as both a noun and an adjective. I have decided to continue this posting to prove how humble I am instead of proving how stupid everyone else was. It also proves the importance of fact checking and, to a degree, the fact that journalists are still relevant in a world filled to the brim with misinformation.
