A participial phrase is a group of words built around a participle, such as carrying, broken, or written. It can describe a person or thing or provide information about an action.
For example:
Holding a folded map, Daniel searched for the trail.
The opening phrase tells us what Daniel was doing while he searched.
Participial phrases can also express reasons, results, and other circumstances. The key is understanding how they connect to the rest of the sentence.
What Is a Participial Phrase?
A participial phrase contains a participle and may include an object, complement, or modifier that completes or adds to its meaning.
Consider:
The woman carrying a large suitcase boarded the train.
The highlighted phrase has two parts:
- Participle: carrying
- Object: a large suitcase
The object tells us what the woman was carrying. Together, these words form a participial phrase modifying woman.
Not every participial phrase needs an object.
Compare:
The children playing outside heard the bell.
Here, playing is the participle, and outside tells us where the children were playing.
Participles are nonfinite verb forms, meaning they do not independently establish tense. The tense of the larger sentence helps establish when the action takes place.

Types of Participial Phrases
Participial phrases commonly use present participles, past participles, and perfect participial constructions.
The form of the participle does not automatically tell you when the action happens. The surrounding sentence establishes the time and relationship between events.
Present Participial Phrases
A present participial phrase uses the -ing form of a verb.
The puppy sleeping beneath the chair belongs to my neighbor.
Sleeping beneath the chair identifies the puppy. It contains the participle sleeping and the prepositional phrase beneath the chair.
Present participial phrases can also describe an activity happening alongside another action.
Listening to the announcement, the passengers gathered near the platform.
The phrase describes what the passengers were doing as they gathered.
The name present participle does not mean the action must happen in the present.
Walking through the orchard, Lena noticed a broken branch.
The main verb noticed places the event in the past. The participle walking describes what Lena was doing when she noticed the branch.
Past Participial Phrases
Past participial phrases use forms such as damaged, written, chosen, and forgotten.
The documents stored in the basement were damaged by moisture.
Stored in the basement identifies the documents.
Past participial phrases often describe something affected by an action or in a particular state.
Surprised by the sudden applause, the speaker paused.
The phrase describes the speaker’s reaction and helps explain the pause.
Many past participles are irregular.
| Base verb | Past participle | Example |
|---|---|---|
| break | broken | the mirror broken during the move |
| write | written | the instructions written on the label |
| choose | chosen | the candidate chosen by the committee |
| freeze | frozen | the pipes frozen overnight |
The term past participle does not necessarily indicate that the action occurred earlier than the main event.
Perfect Participial Phrases
A perfect participial construction uses having + past participle to present an earlier action or experience in relation to the main clause.
Compare:
Reading the report, Maya noticed an error.
Maya noticed the error while reading.
Having read the report, Maya wrote her response.
Maya finished reading before writing her response.
The choice changes the relationship between the events. It is not simply a difference in formality or style.
A perfect participial construction can also explain how an earlier experience relates to a later situation.
Having lived abroad for several years, Daniel understood the difficulties of moving to a new country.
Daniel’s experience of living abroad helps explain his understanding.
Perfect participial constructions can also be passive:
Having been selected for the program, Amir received an invitation.
Amir’s selection took place before he received the invitation.
The passive form makes Amir the person affected by the selection, rather than the person performing it.
What Participial Phrases Can Express
Participial phrases can identify people or things, describe circumstances, explain reasons, or express results.
The relationship is sometimes clear from the sentence without using connecting words such as because or while.
Description or Identification
The technician checking the alarm noticed a fault.
Checking the alarm identifies which technician noticed the fault.
The participial phrase directly modifies technician.
Actions Happening Together
Checking the alarm, the technician noticed a fault.
Now the same words describe what the technician was doing when the fault was noticed.
The participial construction relates to the subject of the main clause, rather than identifying which technician we mean.
Reasons or Background Circumstances
Recognizing the handwriting, Eva opened the envelope immediately.
The phrase helps explain why Eva opened the envelope.
Compare:
Because Eva recognized the handwriting, she opened the envelope immediately.
The second sentence states the reason explicitly.
The participial version allows readers to understand the connection from context.
Results
The technician pressed the wrong button, triggering the alarm.
Here, triggering the alarm expresses the result of pressing the wrong button.
The construction relates to the preceding action rather than simply identifying the technician or describing the button.
Compare another example:
The heavy branch fell onto the fence, damaging several wooden panels.
The damage resulted from the branch falling.
This is different from a noun-modifying participial phrase:
The branch lying across the fence blocked the path.
Here, lying across the fence identifies or describes the branch.
The distinction matters when you decide what the construction refers to. Sometimes it identifies a noun; other times it explains what happened during or after an event.
Placement and Punctuation of Participial Phrases
Where you place a participial phrase affects how readers understand it. Commas help show whether it identifies something or adds extra information.
Introductory Participial Phrases
An introductory participial phrase is normally followed by a comma.
Hurrying toward the exit, Marcus dropped his keys.
The phrase tells us what Marcus was doing when he dropped his keys.
Another example:
Having packed the equipment, the crew left the campsite.
The comma separates the opening participial construction from the main clause.
In both examples, the understood subject of the participial construction is the subject of the main clause.
Identifying Participial Phrases
When a participial phrase is needed to identify which person or thing is meant, commas are normally omitted.
The students waiting near the laboratory will enter first.
The phrase identifies the students who will enter first.
Without it, the sentence would refer more generally to the students.
Supplementary Participial Phrases
When the person or thing is already identified, a participial phrase may add supplementary information.
The students, waiting near the laboratory, checked their notes.
Here, the phrase describes the students’ circumstances rather than selecting one group of students from others.
Commas set the supplementary information apart.
Compare:
| Sentence | How the phrase works |
|---|---|
| The paintings displayed near the entrance are for sale. | Identifies which paintings; no commas |
| The paintings, displayed near the entrance, attracted considerable attention. | Adds supplementary information; commas |
| Noticing the crowd, the artist approached the entrance. | Introductory construction; comma after it |
| The artist approached the entrance, smiling at the visitors. | Adds information about the artist’s action; comma before it |
Participial Phrases at the End
A final participial phrase can describe the subject or add information about the result of an action.
Sofia walked into the classroom, carrying a stack of notebooks.
Sofia was carrying the notebooks as she entered.
The pipe burst overnight, flooding the storage room.
The flooding resulted from the pipe bursting.
These final constructions are supplementary, so commas help separate them from the main clause.
The phrase does not always need to sit directly beside a noun. Its connection to the sentence needs to be clear.
Dangling and Misplaced Participial Phrases
A participial phrase can create confusion when it appears to relate to the wrong person or thing.
Two common problems are dangling and misplaced modifiers.
Dangling Participial Phrases
Consider:
Walking into the kitchen, the smell of fresh bread filled the room.
The opening phrase suggests that the smell was walking into the kitchen.
But the intended person is missing.
Clear revision:
Walking into the kitchen, I noticed the smell of fresh bread.
Now I is the person walking.
You can also use a full clause:
As I walked into the kitchen, the smell of fresh bread filled the room.
Both revisions correct the relationship, but they organize the information differently.
Misplaced Participial Phrases
Consider:
The supervisor spoke to the technician wearing a blue jacket.
As written, the phrase naturally suggests that the technician was wearing the jacket.
That sentence is perfectly acceptable if this is the intended meaning.
However, suppose the supervisor was wearing the jacket. The placement would then be misleading.
Clear revision:
Wearing a blue jacket, the supervisor spoke to the technician.
Now the phrase clearly describes the supervisor.
Before revising a sentence, check what the participial construction is supposed to describe. A phrase is not misplaced merely because it appears after a noun. The problem arises when its position communicates the wrong relationship.
Participial Phrase vs. Gerund Phrase vs. Verb Phrase
Similar verb forms can appear in participial phrases, gerund phrases, and verb phrases.
The difference is their grammatical function.
Compare these sentences.
Participial Phrase
The volunteers painting the fence arrived early.
Painting the fence modifies volunteers. It identifies which volunteers arrived early.
Gerund Phrase
Painting the fence took most of the afternoon.
Here, painting the fence functions as the subject of the sentence.
It names an activity rather than modifying a noun.
Verb Phrase
The volunteers were painting the fence.
Were painting forms the verb phrase of the clause.
The auxiliary were carries tense and agreement, while painting is the main verb form.
The differences are easier to see side by side.
| Construction | Example | Function |
|---|---|---|
| Participial phrase | The workers repairing the roof need more supplies. | Modifies workers |
| Gerund phrase | Repairing the roof requires specialist equipment. | Functions as the subject |
| Verb phrase | The workers are repairing the roof. | Forms the verbal part of the clause |
The -ing ending does not determine the construction’s grammatical role. Look at what the word group does in the sentence.
Participial Phrases and Relative Clauses
Some participial phrases can express information that would otherwise appear in a relative clause.
Compare:
The documents that were stored in the archive were difficult to access.
The documents stored in the archive were difficult to access.
Both highlighted groups identify the documents.
The participial version is shorter, but it preserves the intended meaning.
A similar change is possible with an -ing construction:
The woman who is standing beside the counter is our new manager.
The woman standing beside the counter is our new manager.
Both identify the same woman.
However, not every relative clause can be shortened naturally.
Consider:
The student who owns the bicycle lives nearby.
The wording the student owning the bicycle is possible in some contexts but sounds awkward in ordinary English.
Keeping the relative clause is more natural here.
The choice depends on the verb, the intended meaning, and how the sentence reads. A shorter construction is not automatically better.
How to Identify Participial Phrases: Examples and Practice
To identify a participial phrase, look for a participle and the words connected to it. Then determine how the construction relates to the rest of the sentence.
Consider:
Carrying a tray of glasses, the waiter moved carefully through the crowded room.
The participle is carrying, and its object is a tray of glasses.
The complete participial phrase is:
carrying a tray of glasses
The waiter is the person carrying the tray. The phrase describes what he was doing as he moved.
Now compare:
The photographs damaged by sunlight were removed from the display.
The participle is damaged. The words by sunlight belong with it.
The phrase identifies which photographs were removed.
When checking a participial phrase, ask which words belong to it and what it relates to.
Practice: Identify the Construction
Identify the highlighted construction or decide whether the sentence needs correction.
1. The gardener working beside the greenhouse waved to us.
2. Having completed the survey, the researchers compared their findings.
3. Running along the beach was her favorite morning activity.
4. The guests were waiting outside the auditorium.
5. The vase fell from the shelf, shattering into several pieces.
6. Walking through the park, the flowers looked beautiful.
Answers and Explanations
1. Participial phrase. Working beside the greenhouse modifies gardener. It identifies which gardener waved.
2. Perfect participial construction. Having completed the survey tells us that the researchers finished the survey before comparing their findings.
3. Gerund phrase. Running along the beach functions as the subject of the sentence. It names an activity.
4. Verb phrase. Were waiting forms the verbal part of the clause. The auxiliary were carries tense and agreement.
5. Participial construction expressing a result. Shattering into several pieces describes what happened to the vase as a result of falling from the shelf. It relates to the event in the main clause.
6. Dangling participial phrase. The sentence suggests that the flowers were walking through the park. The intended person doing the walking is missing.
A clearer version is:
Walking through the park, I admired the beautiful flowers.
Now the subject I is also the person walking.
Participial phrases can describe people and things, connect related actions, and show reasons or results. When those relationships are clear, they can make your writing more concise and easier to follow.
