Change the italicized group of words into a prepositional phrase. Then write the complete sentence. Our town has a library. I go there every week.

A prepositional phrase is a structure that contains a preposition and its object. The preposition shows the relationship between a noun or pronoun and another word in the sentence. In this type of phrases, the preposition's object is the noun or pronoun that follows the proposition. "I go every week to our town's library." Would be the way of saying those two sentences in one prepositional phrase.
