A prepositional phrase is a group of words that begins with a preposition and ends with a noun or pronoun, giving information about where, when, how, or why something happens. Phrases such as beneath the surface, before the storm, and with great care are all prepositional phrases.
What is a preposition?
Before understanding a prepositional phrase, you need to know what a preposition is. A preposition is a word that shows the relationship between a noun (or pronoun) and other words in a sentence. Prepositions typically express:
- Place: in, on, under, above, behind, beside, between, through
- Time: before, after, during, since, until, by
- Direction: towards, away from, into, out of, across
- Manner: with, without, by, despite
- Reason: because of, due to, for
Common prepositions in English include: in, on, at, by, for, with, about, against, between, through, under, over, before, after, during, beside, beneath, beyond, towards, despite.
What is a prepositional phrase?
A prepositional phrase consists of a preposition followed by its object — the noun, pronoun, or noun phrase that completes the prepositional relationship — along with any modifiers of that object.
Structure: PREPOSITION + (modifier) + NOUN/PRONOUN
| Prepositional phrase | Preposition | Object |
|---|---|---|
| in the dark forest | in | the dark forest |
| beneath the surface | beneath | the surface |
| before the final bell | before | the final bell |
| with quiet determination | with | quiet determination |
| despite the rain | despite | the rain |
The object of the preposition can be a simple noun (in silence), a pronoun (beside him), or a noun phrase with modifiers (in the cold, grey morning).
What work does a prepositional phrase do in a sentence?
Prepositional phrases function as either adverbials (modifying a verb, adjective, or the whole sentence) or noun phrase modifiers (modifying a noun):
As an adverbial (answering where?, when?, how?, why?):
She waited at the corner of the street. (where?) Before the lesson, he checked his notes. (when?) He spoke with great authority. (how?)
As a noun phrase modifier (telling us more about a noun):
The house at the end of the lane was empty. (which house?) A figure in a dark coat appeared at the door. (which figure?)
How do writers use prepositional phrases for effect?
In creative writing, prepositional phrases are not merely functional — they are a key tool for:
1. Creating atmosphere through precise placement:
In the shadow of the church, the figure waited.
The prepositional phrase "In the shadow of the church" placed at the start of the sentence gives the setting a sinister, gothic quality before we even know who is there.
2. Varying sentence structure:
Prepositional phrases used as fronted adverbials (placed at the beginning of a sentence, before the subject) are a standard KS3 technique for achieving sentence variety:
Without a word, she turned and walked away. Beneath the surface of the lake, something was moving.
Both fronted prepositional phrases build suspense by withholding the main information (who? what?) until after the scene is established.
3. Adding layered detail to description:
The old man sat in the corner of the darkened room, beside the dying fire, with his hands folded in his lap.
Three prepositional phrases, stacked, build a precise and vivid image of stillness and isolation.
How do you identify a prepositional phrase in a text?
Follow these three steps:
- Find the preposition — look for a word showing relationship: in, on, at, beneath, beyond, through, despite, after, before, etc.
- Find its object — the noun or pronoun that comes after the preposition and completes its meaning.
- Include any modifiers — adjectives or articles that sit between the preposition and its noun are part of the phrase: in the old, abandoned house — the entire phrase is the prepositional phrase.
Worked identification:
"The children ran through the narrow gate and into the field beyond the wall."
Two prepositional phrases:
- through the narrow gate (preposition: through, object: the narrow gate)
- into the field beyond the wall (preposition: into, object: the field beyond the wall — note that beyond the wall is itself a prepositional phrase modifying field)
Prepositional phrases can nest inside each other in this way.
Frequently asked questions
Is a prepositional phrase the same as a fronted adverbial?
A fronted adverbial is an adverbial phrase (including many prepositional phrases) placed at the beginning of a sentence, before the subject. All fronted adverbials with prepositional structure are prepositional phrases used in a particular position, but not all prepositional phrases are fronted adverbials. A prepositional phrase can appear anywhere in a sentence; a fronted adverbial is, by definition, at the front.
Can a preposition come at the end of a sentence?
Yes, in everyday English this is common and perfectly acceptable. "This is the house I grew up in" is standard spoken and informal written English, despite the old prescriptive "rule" that sentences should not end with prepositions. That rule was never a genuine rule of English grammar — it was borrowed from Latin, where ending with a preposition is impossible. You may hear it repeated, but it is not a standard modern grammar requirement.
Why do prepositional phrases matter in creative writing?
Precise prepositional phrases are one of the most reliable ways to add detail, atmosphere, and variety to writing. A sentence like "The figure walked" tells the reader little; "The figure walked through the fog, towards the unlit house, with a deliberate, unhurried step" creates presence, atmosphere, and narrative tension. Accumulating precise prepositional phrases is a skill directly assessed in KS3 and GCSE creative writing.
What is the difference between a prepositional phrase and a noun phrase?
A noun phrase is built around a noun and includes any determiners, adjectives, or other modifiers of that noun: the old, crumbling castle. A prepositional phrase is built around a preposition and includes the noun phrase that follows it: inside the old, crumbling castle. A prepositional phrase always contains a noun phrase as its object; a noun phrase does not require a preposition.
