Answer:
A prepositional phrase begins with a preposition and ends with a noun or pronoun (the object of the preposition). A preposition is a kind of connector word. It shows how the noun or the pronoun in the prepositional phrase connects to the rest of the sentence. Common prepositions are words like "at," "of," "to," "from," "above," and "near." Prepositions are very powerful in writing because they show the relationship between things and ideas.
