Prepositional phrases consist of a preposition followed by a noun or pronoun known as the object of the preposition. There are two main types of prepositional phrases: adjective phrases which modify nouns, and adverb phrases which modify verbs. Examples are given such as "with Ben" and "to the beach". A prepositional phrase can also contain multiple phrases that together modify a noun or verb. Distinguishing prepositional phrases from infinitives is explained, with infinitives containing "to" followed by a verb rather than a noun.
