Here's what you might be thinking of:
* Antecedent: This is the word or phrase that a pronoun refers to. For example, in the sentence "The cat sat on the mat, and *it* purred," the antecedent of the pronoun "it" is "the cat."
* Prepositional Phrase: This is a phrase that starts with a preposition and modifies a noun or pronoun. For example, "in the garden," "on the table," or "with a smile."
Confusion:
People might use the term "antecedent phrase" to describe a phrase that functions as the antecedent of a pronoun. However, this is not a standard grammatical term. It's more accurate to refer to the entire phrase that contains the antecedent.
Example:
* Incorrect: "The phrase 'the big red ball' is the antecedent phrase of 'it' in the sentence 'The big red ball bounced, and it rolled away'."
* Correct: "The phrase 'the big red ball' is the antecedent of the pronoun 'it' in the sentence 'The big red ball bounced, and it rolled away'."
