How do you change eloquent in to a noun?

"Eloquent" is already a noun! It's a bit tricky because it can be both an adjective (describing something as fluent and persuasive) and a noun (meaning the quality of being eloquent).

Here's how it works:

* Adjective: "The speaker gave an eloquent speech."

* Noun: "Her eloquence was captivating."

So, you don't need to change "eloquent" into a noun, you just need to use it as one!
