A prepositional phrase works like a bridge in a sentence.

What Is a Prepositional Phrase? An Explanation With Examples

I like to imagine prepositions as little grammatical bridges; they are the structures that connect one element of a sentence to the next. However, they need solid support on either side, or else they slide purposelessly into an infinite abyss of wasted words.

So, the next step is to build a functional unit where the preposition has a destination or a grammatical object to relate to. We do this by combining the preposition with a noun to form a prepositional phrase.

What Is a Prepositional Phrase Definition?

Let’s start with a simple question and build from there: What is a prepositional phrase definition?

Prepositional phrase (noun): a phrase that starts with a preposition and ends in either a noun, noun phrase, or pronoun.

What Is a Prepositional Phrase?

A prepositional phrase, at the very minimum, consists of a preposition and its object and frequently includes a direct or indirect article.

  • at the studio
  • in the car

It can also incorporate modifiers that further define the object. These can be noun adjuncts, adjectives, and even other prepositional phrases.

  • at the television studio
  • in the blue car next to the building
A blue car next to a building is the subject next to a prepositional phrase.

Prepositional phrases then function as either adjectives or adverbs.

Adjectival prepositional phrases provide additional meaning about a noun (or element acting as a noun) such as quantity or amount, attributes or characteristics.

  • Park in the lot with fewer cars.
  • The studio on the east side is where we need to go.
  • My mom said she would bring a bag of snacks for us.

Adverbs modify verbs, as well as adjectives and other adverbs, and so have a broader function than adjectives do. They answer these questions: wherewhenfor what purposein what way, and to what extent?

Like their adjectival counterparts, adverbial prepositional phrases generally follow the adjective or adverb that it modifies. When they are used to modify verbs, however, they may appear several elements away from their target.

  • We got to the studio faster in your car than we would have on the train.
  • I was really happy for the chance to appear on “Jeopardy!”
  • I think we should wait for my mom inside the studio.

How Do Prepositional Phrases Express Relationships?

The primary function of a preposition is to form and express a relationship between its object and another word, phrase or clause. Preparing for a round in the “Relationship” category, however, would involve data centers full of electronic literature, a liberal interpretation of the word, and probably several lifetimes.

Fortunately for us, prepositions can be broadly categorized based on the type of relationship they convey:

  • Place
  • Direction or Movement
  • Time
  • Reason or Purpose
  • Agency
  • Origin
  • Connection
  • Instrument or Device

The vast majority of prepositions used in everyday speech and literature fall neatly into one of these categories. There are instances, though, when defining the relationships between abstract concepts and the prepositional phrases that qualify them can present a Double Jeopardy-level challenge.

Either way, by breaking down the sentence into its grammatical elements and examining the context, we can usually identify and categorize even the most elusive prepositions.

Place

A man in a suit kicks a teddy bear, using prepositional phrases to clarify its position

Once, I had a boss who referred to tangible property as something you could kick. He was talking about classifying business expenses, but all the same; prepositions of place always indicate a physical location that you can see, touch, or kick. They can define a place as compared to a reference point or designate the position of a person, event, or object.

Place Prepositions Prepositional Phrase Examples
atinonI’m standing at my podium on the set of “Jeopardy!”Our guests will be in the studio, sitting on the main floor.
nearbyclose toI can see my mom standing by the souvenir shop. They let us park near the studio. Will you stay close to me?
next tobetweenI really hope my podium is next to yours. There’s an extra set of speakers between the audience and us.
behindaboveunderbelowMy mom is sitting behind a really tall person. Will the lights above the stage make us hot? I’m getting too hot under these lights. Maybe they’ll let me keep a glass of water below my podium.

Direction or Movement

These prepositions qualify the actual motion between those kickable locations. They include describing the way something moves, how it moves, or where it goes.

Direction PrepositionsPrepositional Phrase Examples
tofromWe might get there faster if we go to the left here. Let’s wave at my mom when she walks in from the lobby.
underbeneathaboveoverI jumped out from under my blankets at 5 a.m.I reached beneath my bed to find my shoe. The sun was just rising above the horizon as we left.We had a great view of it as we drove over the river.

towardaway fromintoontooffHe stalked toward us waving a rake.We ran away from him and into the studio. We climbed onto a low partition and waited for someone to find us.We jumped off the wall and sat on the benches instead.

Time

Prepositions of time answer "when"

Prepositions of time answer the question “When?” and are used to indicate specific moments or general periods of time in the past, present or future. They can also describe precise or ambiguous lengths of time. Time prepositions are usually specific to the period or interval they describe.

Time PrepositionsPrepositional Phrase Examples
atinonWe need to leave at 6 a.m.We started watching “Jeopardy!” regularly in 2003. Our show will air on a Friday.
forduringasThe drive to the show was short but seemed to last for hours. We discussed our strategies during the drive. You were competitive as a kid.
bysinceuntilafterbeforeThe producer said that we must arrive by 7 a.m.I haven’t been this nervous since I took my SATs.We’ll probably be there until 8 p.m. or so.Will we see the host at all after Final Jeopardy?I’ve never done anything this cool before now.
pasttoWe pulled into the parking lot at twenty past six.The filming ran long, and we left at a quarter to nine.

Reason, Purpose, or Role

The function of reason and purpose prepositions is to help explain why. They can either describe the cause or nature of an event or state of being or why that event or state is happening.

Reason PrepositionsPrepositional Phrase Examples
because ofWe arrived at the studio early because of light traffic.
asWe had special badges that marked us as competitors.
forI’m appearing on “Jeopardy!” for personal satisfaction rather than to win.
fromYour drive to succeed stems from sheer determination.
on account ofI think you’ll win on account of your dedication to trivia.
throughWe discovered friendship through our love of “Jeopardy!”

Agency

Also known as instrumentality or causation, agency is one of those elusive, abstract relationships I touched on earlier. The concept is the same as that of a real-life agent — you know, the person you hire as the middle-person (the instrument) to “make it all happen” (causation) after your massive “Jeopardy!” winnings render you too important to manage your own schedule. Since prepositions of agency place the emphasis on the happening, the sentence structure naturally utilizes the passive voice.

Agency PrepositionsPrepositional Phrase Examples
withMy stomach felt like it was filled with butterflies.
byWe were inspired by Ken Jennings.

Connection

Answer and fill in the blank: Another word for relationship, the primary function of a preposition is to express the ______ between grammatical elements.

If you asked, “What is connection?” you’re correct and probably wondering why this broad brush has its own category.

Prepositions specific to connection are reserved for the most literal interpretations of the concept; that is, physically being in the same place at the same time, having ownership or custody, and attachments to people or objects.

Connection PrepositionsPrepositional Phrase Examples
withCome with me and say hi to my mom.
ofThis section of the studio still boasts the original architecture.
toYou have been such a great friend to me.

Instrument or Device

A train station is a perfect setting for the use of prepositional phrases in conversation.

The prepositions paired with tools that are used to perform actions are prepositions of instrument or device. These usually refer explicitly to devices, equipment or technology used for transportation or performing tasks, but they can sometimes represent intangible means.

Instrument PrepositionsPrepositional Phrase Examples
onWe played a lot of trivia games on our cell phones.
withArmed with copious irrelevant knowledge, we marched onto the “Jeopardy!” stage.
byWe probably could have gotten to the studio by train.

Origin

Prepositions of origin convey, quite literally, where something came from. This includes the location or entity that designed or manufactured an object, the source of an idea or concept, or the origin of a person, including cultural and ethnic identity, birthplace and area of residence.

Origin PrepositionsPrepositional Phrase Examples
offrom“Jeopardy!” was a creation of Merv Griffin, who was from California.
out ofWe observed a moment of silence for Alex Trebek out of respect.

As I’m sure you’ve realized by now, many of the most commonly used prepositions fall into more than one category. If your goal is to avoid grammar and clarity issues in your writing that involve incorrect preposition usage, this will be important to remember.

So, What Is a Prepositional Phrase and Its Purpose Again?

We’ve gone into great detail about the types of little grammatical bridges and what kinds of clause elements each preposition can and cannot connect. But, it’s crucial to remember what is a prepositional phrase because without those elements, or prepositional objects, prepositions are a bridge to nowhere. Keep this in mind as you start exploring the purpose of prepositional phrases and the limitless opportunities they provide for added definition and color in speech.
