prepositional phrase
Noun: A prepositional phrase is a grammatical structure that functions as a single unit within a sentence. It begins with a preposition (e.g., in, on, at, with, for, about) and is followed by its object, which is typically a noun, pronoun, or noun phrase (e.g., the house, her, a long journey). The entire phrase acts as a modifier, providing additional information about location, time, manner, reason, or other relationships.
A prepositional phrase can modify a noun, a verb, or an entire sentence. Its role is to add detail and context. - Modifying a noun (acts as an adjective): The phrase describes which one or what kind. - Modifying a verb (acts as an adverb): The phrase describes how, when, where, or why an action occurs.
Modifying a noun:
- The book on the shelf is mine. (Specifies which book.)
- A woman with great courage spoke to the crowd. (Describes what kind of woman.)
Modifying a verb:
- She slept during the movie. (Tells when she slept.)
- They walked through the park. (Tells where they walked.)
- He works for a charity. (Tells why or for what purpose he works.)
As a sentence modifier:
- In my opinion, the plan is flawed. (Modifies the entire statement.)
- Multiple prepositional phrases: Sentences can contain several prepositional phrases.
- The keys are in the drawer under the desk in the study.
- Prepositional phrases vs. phrasal verbs: It is important not to confuse a prepositional phrase with the particle in a phrasal verb. In a phrasal verb (e.g., , ), the word following the verb is a particle, not a preposition introducing a phrase with an object. Compare:
- She looked after the children. (Phrasal verb: looked after means 'cared for'.)
- She looked after the storm passed. (Prepositional phrase: after the storm passed tells when she looked.)
- Preposition (n): The word that begins the phrase (e.g., , , , ).
- Object of the preposition (n): The noun, pronoun, or noun phrase that follows the preposition and completes the phrase.
- Adpositional phrase: A more formal linguistic term that includes both prepositions and postpositions.
- Modifying phrase: A general term for a phrase that provides additional description.
- Absolute phrase: A modifying phrase that contains a noun and a participle but is not connected to the main clause by a conjunction (e.g., , she went home). This is structurally different from a prepositional phrase.
- Infinitive phrase: A phrase beginning with "to" followed by the base form of a verb (e.g., ). This is distinct from a prepositional phrase starting with the preposition "to" (e.g., ).
- A prepositional phrase always contains a preposition and its object. It never contains a finite verb (a verb that shows tense).
- The object of the preposition can sometimes be a gerund (a verb form ending in that functions as a noun), as in "She is good ."
