Here's the breakdown:
* Adjective: A word that describes a noun or pronoun (e.g., beautiful, tall, red).
* Phrase: A group of words that functions as a single unit but doesn't contain a subject and verb.
* Adjective Phrase: A group of words that modifies (describes) a noun or pronoun and starts with an adjective.
Example:
* The very tall building (adjective phrase) is a landmark.
In this example, "very tall" is the adjective phrase that modifies the noun "building." It starts with the adjective "tall."
