Does an adjective describe a noun?

Yes, that's the primary function of an adjective. An adjective is a word that describes or modifies a noun, providing more information about its qualities, characteristics, or attributes.

Here's a breakdown:

* Noun: A word that names a person, place, thing, or idea (e.g., dog, park, book, happiness).

* Adjective: A word that describes a noun (e.g., big dog, green park, old book, intense happiness).

Example:

* The red car is parked in the long driveway.

* "Red" describes the car (noun).

* "Long" describes the driveway (noun).

Essentially, adjectives enhance the understanding of nouns by adding color, detail, and specificity.
