Which of the following is a prepositional phrase functioning as an adverbial of place? In the sentence 'The cat is on the roof,' 'on the roof' functions as what?

• A. Noun phrase
• B. Adverbial of place
• C. Prepositional phrase
• D. Adjective clause

Answer: (B)

A phrase that tells us where something happens is an adverbial of place. In the sentence The cat is on the roof, the group on the roof is built from the preposition on plus its object the roof. This unit modifies the verb be (is), answering the question where is the cat? so its function is adverbial of place. It’s not a noun phrase because it doesn’t serve as a noun; it’s not an adjective clause because there’s no relative clause structure. It is a prepositional phrase whose role here is to indicate location.
