Participial Clauses
Learn how participle clauses express time, reason, condition, contrast and passive meaning—and practise using them accurately.
1. What is a participle clause?
A participle clause uses a participle instead of a full clause. It can make writing more concise and add information about time, reason, condition, contrast or an accompanying action.
Full clause: Because she felt unwell, she cancelled the meeting.
Participle clause: Feeling unwell, she cancelled the meeting.
The implied subject of feeling unwell is she—the subject of the main clause.

2. The main forms
- Present participle (-ing): active meaning; often simultaneous action or reason.
Noticing the mistake, she corrected it. - Perfect participle (having + past participle): earlier completed active action.
Having checked the data, he published the results. - Past participle: passive meaning or a state.

Choose: time / reason / earlier action / condition / contrast.

4. Reducing full clauses
A participle clause can often replace a subordinate clause when its subject is the same as, or clearly understood from, the main clause.

→ While waiting for the interview, I reviewed my notes.

The documents receive the action. Try beginning with “Signed yesterday…”.
3. After we had discussed the proposal, we voted on it.
Hint

- While travelling through South America, she kept a journal.
Other grammatically correct versions may be possible.
5. Perfect participles and passive forms
Use having + past participle to make it clear that one action was completed before the main action.
Use having been + past participle when the earlier action is passive.
Practice: Complete the sentences
1. ______ the report, the researchers submitted it to the journal. (finish — active, earlier action)
Hint
Use “Having…” followed by the past participle of finish.
2. ______ several times, the proposal was finally accepted. (revise — passive, earlier action)
Hint
Use “Having been…” + past participle.
3. ______ the warning signs, the hikers decided to turn back. (notice — active, reason)
Hint
They noticed the signs before deciding.
6. Avoiding dangling participles
The subject of the participle clause should normally be the same as the subject of the main clause.
Unclear: Walking into the room, the music sounded unusually loud.
Clear: Walking into the room, I noticed that the music sounded unusually loud.
Practice: Correct the sentences
1. Driving through the city, the historic buildings caught our attention.
Hint
Who was driving? Make that person the subject of the main clause.
2. Having completed the assignment, the television was turned on.
Hint
Who completed the assignment and turned on the television?
3. Covered in dust, Maria carefully opened the old suitcase.
Hint
What was covered in dust? Move the participle phrase next to that noun or rewrite the sentence.

- Having completed the assignment, I turned on the television.
- Maria carefully opened the old suitcase, which was covered in dust. / Covered in dust, the old suitcase was carefully opened by Maria.
