What is a noun or pronoun placed beside another to identify describe?

That's a great question! The word you're looking for is adjective.

Here's why:

* Nouns are words that name people, places, things, or ideas (e.g., dog, park, book, happiness).

* Pronouns are words that replace nouns (e.g., he, she, it, they).

* Adjectives are words that describe or modify nouns and pronouns, providing more information about them.

For example:

* The red car - "Red" is an adjective describing the noun "car."

* She is beautiful. - "Beautiful" is an adjective describing the pronoun "she."
