Notional grammars traditionally define prepositions as words that “link to other words, phrases, and clauses” and that “express spatial or temporal relations.” A prepositional phrase is a phrase that consists of a preposition plus another word, phrase, or clause functioning as the prepositional complement.
In grammar, a direct object is a word, phrase, or clause that follows and receives the action of a transitive verb. Although nouns, pronouns, and noun phrases most frequently perform the function, prepositional phrases sometimes, although rarely, function as direct objects in English. Examples of prepositional phrases as direct objects include the following:
- You must organize under the bed.
- Her sister is painting along the ceiling.
- My grandfather scrubbed behind the freezer.
- I will decorate on top of the roof.
