1. Prepositions are words that connect nouns and pronouns to other words in the sentence. The noun or pronoun is called the object of the preposition. A prepositional phrase consists of the preposition, the object of the preposition, and all the modifiers of the object.
2. The prepositional phrase works as an adjective (telling what kind or whose), adverb (telling where, when, how, or how often), or noun (when the phrase serves as a subject of the verb or a direct object) in the sentence depending upon its purpose in connecting the object to another word in the sentence.
