Here's what's likely meant:
* A phrase with a pronoun as its head: This means the pronoun is the main word in the phrase, acting as its core element.
* Example: "She with the red hat" (pronoun "she" is the head of the phrase)
* A phrase that refers to a pronoun: This means the phrase explains or modifies a pronoun that appears earlier in the sentence.
* Example: "They were very excited about the trip, especially John." (the phrase "especially John" refers back to the pronoun "they")
Instead of "pronoun phrase," consider these more accurate terms:
* Pronoun: This refers to the word itself, such as "he," "she," "it," "they," "we," "you," "I," or "who."
* Pronoun clause: This is a clause (with a subject and verb) that functions as a pronoun.
* Example: "Whoever wins the race will be declared the champion."
* Prepositional phrase: This is a phrase that starts with a preposition and modifies a noun or pronoun.
* Example: "The book on the table belongs to me."
* Appositive phrase: This is a phrase that renames or identifies a noun or pronoun.
* Example: "My dog, a playful golden retriever, loves to fetch."
