Modifiers

A modifier is a word, phrase, or clause that gives extra information about another word in a sentence. You already know that adjectives and adverbs are modifiers. Now you will learn how prepositional phrases can also work as modifiers, and how to place all modifiers in the right position so your sentences are clear.

What You'll Learn

How prepositional phrases can modify nouns (like adjectives) and verbs (like adverbs)
How to tell whether a prepositional phrase is modifying a noun or a verb
How to place modifiers close to the words they describe
How moving a modifier can change the meaning of a sentence

When to Use

Giving more detail about a noun: "The girl with the ponytail won the race." (The prepositional phrase tells us which girl.)
Telling where something happened: "The cat slept on the warm windowsill." (The prepositional phrase tells us where the cat slept.)
Telling when something happened: "We have swimming lessons on Fridays." (The prepositional phrase tells us when.)
Describing how something was done: "She spoke with great confidence." (The prepositional phrase tells us how she spoke.)
Making your writing more specific: "The book about dinosaurs on the top shelf belongs to my brother." (Two prepositional phrases give extra detail.)

How to Form

What Is a Prepositional Phrase?

A prepositional phrase starts with a preposition and ends with a noun (or noun phrase). It works as a modifier by telling us more about a noun or a verb.

Preposition	Prepositional Phrase	What It Tells Us
with	with a bright smile	which / what kind
on	on the kitchen counter	where
in	in the early morning	when
from	from the neighbourhood	which / where
near	near the hawker centre	where
of	of colourful beads	what kind

Prepositional Phrases That Modify Nouns

When a prepositional phrase comes right after a noun, it works like an adjective -- it tells us which one or what kind.

Noun Alone	With Prepositional Phrase Modifier	What It Tells Us
the boy	the boy in the red shirt	which boy
a necklace	a necklace of colourful beads	what kind
the house	the house near the MRT station	which house
the students	the students from the other class	which students
the cake	the cake with chocolate icing	what kind

Prepositional Phrases That Modify Verbs

When a prepositional phrase tells us where, when, or how about the verb, it works like an adverb.

Sentence Without Modifier	With Prepositional Phrase Modifier	What It Tells Us
The children played.	The children played at the playground.	where
She practises the piano.	She practises the piano every day after school.	when
He answered the question.	He answered the question with confidence.	how
The bird flew.	The bird flew over the rooftops.	where

How Placement Changes Meaning

The position of a prepositional phrase can change which word it modifies -- and change the meaning of the whole sentence.

Sentence	Meaning
The man saw the monkey with binoculars.	The man used binoculars to see the monkey.
The man saw the monkey with the long tail.	The monkey had a long tail.
She served the cake on the plate to her friends.	The cake was on the plate.
She served the cake to her friends on the patio.	The serving happened on the patio.

Key Rules

Place a modifier close to the word it describes: A prepositional phrase that describes a noun should come right after that noun. "The girl with the red ribbon smiled" is clear. "The girl smiled with the red ribbon" is confusing -- it sounds like she used a ribbon to smile.
A prepositional phrase after a noun usually modifies that noun: "I saw the dog in the garden" -- most likely describes where the dog is. If you mean where you saw it, rearrange: "In the garden, I saw the dog."
A prepositional phrase at the end of a sentence often modifies the verb: "She read her book in the library" -- "in the library" tells where she read. It modifies the verb "read".
You can move a prepositional phrase to the front for emphasis: "After the assembly, the pupils returned to class." Moving it to the front highlights when the action happened. Use a comma after a prepositional phrase that starts a sentence.
Do not let a modifier sit between two words it could describe: If "on the table" could describe either "the vase" or "placed", make the meaning clear by moving the phrase. Unclear: "He placed the vase on the table carefully." Clear: "He carefully placed the vase on the table."
Check that every modifier has a clear word to describe: Every prepositional phrase should clearly point to a specific noun or verb. If a reader cannot tell which word the phrase describes, move it closer to the correct word.

Common Mistakes

Wrong	Right	Why
The boy kicked the ball with the blue shirt.	The boy with the blue shirt kicked the ball.	"With the blue shirt" describes the boy, not the ball -- move it next to "boy"
I saw a bird walking to school.	Walking to school, I saw a bird.	As written, it sounds like the bird was walking to school -- move the modifier to show who was walking
She ate the sandwich sitting on the bench cold.	She ate the cold sandwich sitting on the bench.	"Cold" describes the sandwich -- place adjectives before the noun they modify
The teacher spoke to the pupils with a loud voice in the hall.	In the hall, the teacher spoke to the pupils with a loud voice.	Two prepositional phrases in a row can cause confusion -- separate them for clarity
He found the ring of his mother under the sofa.	He found his mother's ring under the sofa.	"Of his mother" should stay close to "ring" or be rewritten to avoid confusion with "under the sofa"
With a big smile the girl waved at her friends.	With a big smile, the girl waved at her friends.	A prepositional phrase at the start of a sentence needs a comma after it

Clue Words

Common prepositions that begin modifier phrases:

in, on, at, with, from, of, near, by, for, about, between, behind, beside, under, over, through, across, along, after, before, during

Questions to identify what a modifier describes:

Which one? -- the phrase modifies a noun (e.g., "the girl in the blue dress")
What kind? -- the phrase modifies a noun (e.g., "a book about space")
Where? -- the phrase modifies a verb (e.g., "They played in the park")
When? -- the phrase modifies a verb (e.g., "We left after lunch")
How? -- the phrase modifies a verb (e.g., "He spoke with excitement")

Tip: If you are not sure which word a prepositional phrase modifies, try moving it right next to the word you think it describes. If the sentence still makes sense and means what you want, you have placed it correctly.

Practice Tips

The "which word?" test: For every prepositional phrase in your sentence, ask: "Which word does this describe?" If the answer is unclear, move the phrase closer to the word it should modify.
Try moving the phrase: Rewrite the sentence with the prepositional phrase in different positions. Choose the position where the meaning is clearest and there is no confusion.
Read aloud for oddness: Read your sentence out loud. If something sounds funny or confusing -- like a bird walking to school -- a modifier is probably in the wrong place. Move it.
One phrase at a time: When a sentence has more than one prepositional phrase, check each one separately. Ask what it modifies and whether it is in the best position.
