Participle Clauses
Learn how a participle clause shortens a full clause into a more compact phrase, using an -ing or -ed form of a verb instead of a separate subject and verb.
A shorter way to add information
A participle clause replaces a full clause with a shortened one.
A participle clause is a shortened clause built around a participle, such as an -ing form or an -ed form, instead of a full clause with its own subject and a fully conjugated verb.
Compare Because she felt tired, she went to bed. with Feeling tired, she went to bed. Both sentences share the same meaning, but the second replaces the full clause because she felt tired with the shorter participle clause feeling tired.
Participle clauses are common in both written and spoken English, and are especially useful for combining closely related ideas more concisely.
Before you begin
Participle clauses are one structure within advanced grammar.
This lesson focuses on participle clauses specifically. If you would like an overview of the other structures covered under advanced grammar, begin with the Advanced Grammar page.
The central idea
A participle clause has no separate subject of its own.
Compare a full clause with its shortened participle clause version.
01
Full Clause
Includes its own subject and a fully conjugated verb.
Because she felt tired, she went to bed.
02
Participle Clause
Shortens the clause, with no separate subject.
Feeling tired, she went to bed.
The useful question is: Who is the participle clause really about?
Feeling tired, she went to bed.
The participle clause has no subject of its own, so it borrows the subject of the main clause. Here, she is understood to be the one feeling tired.
Present participle clauses
Built with the -ing form, often for an active meaning.
Describing an action happening at the same time
Walking through the park, I noticed the trees had begun to change colour.
The walking and the noticing happen around the same time, and the subject of both actions is the same person, I.
Replacing a reason clause
Knowing the roads well, she chose a faster route.
This participle clause replaces a fuller reason clause, such as because she knew the roads well.
Past participle clauses
Built with the -ed form or an irregular past participle, often for a passive meaning.
Describing something that was done to the subject
Written in 1932, the novel remains popular today.
This shortens a passive clause such as which was written in 1932. The novel did not write itself, so the participle takes a passive meaning.
Another example
Exhausted by the long journey, they went straight to sleep.
They were exhausted by the journey, rather than exhausting it.
Perfect participle clauses
Built with “having” plus a past participle, to show one action happened before another.
Showing a completed action before the main action
Having finished the work, she went home early.
Having finished shows that finishing the work happened before going home, replacing a fuller clause such as after she had finished the work.
Comparing with a simple -ing clause
Finishing the work, she went home. → suggests the actions overlap closely
Having finished the work, she went home. → makes it clear the work was already complete
Adding having makes the order of events clearer when it matters to the meaning.
Replacing relative clauses
A participle clause can shorten a relative clause describing a noun.
Shortening an active relative clause
The man who is standing by the door is my uncle.
The man standing by the door is my uncle.
The relative pronoun and the verb is are both removed, leaving just the -ing form.
Shortening a passive relative clause
The documents that were left on the desk have gone missing.
The documents left on the desk have gone missing.
Here, the relative pronoun and were are removed, leaving the past participle.
Matching the subject
The subject of the participle clause must match the subject of the main clause.
A mismatch creates confusion
Walking through the park, the trees looked beautiful.
As written, this sentence suggests that the trees were walking through the park, since the participle clause has no subject of its own and automatically borrows the subject of the main clause.
Correcting the mismatch
Walking through the park, I thought the trees looked beautiful.
Changing the main clause so its subject genuinely matches the implied subject of the participle clause fixes the confusion.
A useful decision guide
Ask what the participle clause needs to express.
01
Does the subject perform the action?
Use the -ing form for an active meaning.
02
Does something happen to the subject?
Use the -ed or irregular past participle form for a passive meaning.
03
Did the action finish before the main clause’s action?
Use having plus the past participle to make that order clear.
04
Does the subject of the main clause match the implied subject?
Check carefully, since the participle clause always borrows the main clause’s subject.
Common mistakes
Do not let the participle clause’s subject drift away from the main clause.
Creating a dangling participle.
Not: Having cooked dinner, the smoke alarm went off.
Correct: Having cooked dinner, she set off the smoke alarm.
The smoke alarm did not cook dinner, so the main clause’s subject must genuinely match.
Using -ing where a passive meaning is needed.
Not: Writing in 1932, the novel remains popular.
Correct: Written in 1932, the novel remains popular.
The novel was written, rather than doing the writing itself, so the past participle is needed.
Leaving out “having” when the order of events matters.
Less clear: Finishing her homework, she watched television for two hours.
Clearer: Having finished her homework, she watched television for two hours.
Having makes it clear that the homework was already complete before the television started.
Check your understanding
Which participle form fits?
Choose the correct answer for each sentence.
__________ nervous, she took a deep breath before the interview.
✅ Exactly! She is actively feeling nervous, so the -ing form is correct.
❎ Not quite. Ask whether the subject is actively feeling something, or having something done to her.
Nervousness is an active feeling, not something done to her by someone else.
__________ in the 1800s, the bridge is still standing today.
✅ Exactly! The bridge was built, rather than doing the building itself.
❎ Not quite. The bridge did not build itself, so this needs a passive meaning.
__________ dinner, we decided to go for a walk.
✅ Exactly! Having eaten makes it clear that dinner was already finished before the walk.
❎ Not quite. Think about whether eating and walking happened at the same time, or one after the other.
“Having cooked dinner, she set off the smoke alarm.” Does the subject match correctly?
✅ Exactly! She is the one who both cooked dinner and set off the alarm.
❎ Not quite. Check who the participle clause and the main clause both refer to.
Choose the best explanation
Select the sentence that explains the participle clause correctly.
Why is “Walking through the park, the trees looked beautiful” a dangling participle?
✅ Exactly! The participle clause borrows whatever subject follows it, which here creates an unintended meaning.
❎ Not quite. Think about who is logically doing the walking in this sentence.
Why does “Having finished her homework, she watched television” use having finished rather than finishing?
✅ Exactly! The perfect participle clarifies that one action was fully completed before the next began.
❎ Not quite. Think about the order of the two actions in this sentence.
Which sentence correctly shortens “The documents that were left on the desk have gone missing”?
✅ Exactly! The past participle left correctly shortens the passive relative clause.
❎ Not quite. The documents were left there, rather than doing the leaving themselves.
Try it another way
Complete each participle clause.
Type the correct participle form of the verb shown in brackets.
✅ Exactly! They were exhausted by the flight, so the past participle is used.
❎ Not quite. The flight exhausted them, not the other way around.
✅ Exactly! He is actively carrying the bags, so the -ing form is correct.
❎ Not quite. He is performing the action of carrying, so this needs an active form.
✅ Exactly! Checking the forecast happened before deciding to postpone.
❎ Not quite. Think about which action happened first.
Edit the sentence
Rewrite each pair of sentences using a participle clause.
Combine the two ideas into one sentence.
She realised she had left her phone at home. She turned the car around. (combine using a participle clause)
✅ Exactly! Realising… shortens the first sentence into a participle clause.
❎ Not quite. Turn the first sentence into an -ing clause, and keep the same subject in both parts.
The fence was painted bright red. It stood out against the garden. (combine using a participle clause)
✅ Exactly! Painted… shortens the passive first sentence into a past participle clause.
❎ Not quite. The fence was painted, so this needs a past participle, not an -ing form.
He finished the marathon. After that, he collapsed onto the grass. (combine using a perfect participle clause)
✅ Exactly! Having finished… shows that the marathon was completed before he collapsed.
❎ Not quite. Use having plus the past participle to show the correct order of events.
Quick review
A shortened clause, with the subject borrowed from the main sentence.
A participle clause shortens a full clause, replacing its subject and finite verb with a participle form.
Present participle clauses (-ing) usually carry an active meaning.
Past participle clauses (-ed or irregular) usually carry a passive meaning.
Perfect participle clauses (having + past participle) show that one action finished before another began.
Participle clauses can also shorten relative clauses describing a noun.
The subject of the participle clause is always understood to be the subject of the main clause; a mismatch creates a dangling participle.
Remember
Ask who the shortened clause is really about.
A participle clause has no subject of its own, so it silently borrows the subject of the main clause. Checking that this borrowed subject actually makes sense is the surest way to avoid a dangling participle.
