The most basic sentence structure in English is a subject plus a verb. A subject performs the action in the sentence, and the verb identifies the action. Keep in mind that in some languages, such as Spanish and Italian, an obvious subject does not always perform the action in a sentence; the subject is often implied by the verb. However, every sentence in English must have a subject and a verb to express a complete thought.
Not all sentences are as simple as a subject plus a verb. To form more complex sentences, writers build upon this basic structure. Adding a prepositional phrase to the basic sentence creates a more complex sentence. A preposition is a part of speech that relates a noun or a pronoun to another word in a sentence. It also introduces a prepositional phrase. If you can identify a preposition, you will be able to identify a prepositional phrase.
On is the preposition. On the couch is the prepositional phrase.
