* Adjectives describe: They tell us more about the noun or pronoun, adding qualities, characteristics, or details.
* Nouns and pronouns remain nouns and pronouns: Even with adjectives, the noun or pronoun still acts as the subject, object, or other grammatical element in the sentence.
Example:
* The blue car is fast.
* "Blue" describes the car, but the car is still the subject of the sentence.
Therefore, adjectives do not change the grammatical function of a noun or pronoun, they simply modify them.
