Here's why:
* Definition: Eminent means "famous and respected within a particular sphere."
* Example: "The eminent scientist gave a lecture on climate change." In this sentence, "eminent" describes the scientist.
However, "eminent" can also be used as a noun in rare cases. This usage refers to a person who is outstanding in their field.
* Example: "The legal team included several eminents in their field." In this sentence, "eminents" refers to the outstanding lawyers.
Therefore, while the primary use of "eminent" is as an adjective, it can also be used as a noun in specific contexts.
