Here's why:
* Verb: The core of the phrase is "have been," which is a form of the verb "to be."
* Phrase: It's a group of words that acts as a single unit and expresses an action or state of being.
* Present Perfect Tense: The phrase is in the present perfect tense, indicating an action that started in the past and continues to the present or has a result in the present.
For example, in the sentence "I have been to Paris," "I have been" is the verb phrase that tells us about the speaker's past experience.
