π§© Lesson 3.2: Relative & Participle Clauses
You already know how to add information with who, which and that. Now you'll learn the elegant B2 move that separates fluent writers from careful ones: cutting those clauses down to lean participle phrases. "The man who is standing there" becomes "the man standing there." Same meaning, fewer words, twice the polish.
π What You'll Learn
By the end of this lesson, you will be able to:
- Review the difference between defining and non-defining relative clauses
- Reduce relative clauses to participle clauses β active to -ing, passive to -ed
- Combine two ideas into one concise sentence using a participle clause
- Use participle clauses to show time, reason and sequence β and avoid the dangling participle error
β±οΈ Estimated Time: 55β65 minutes
π― Project: Describe a scene, a process, or a person's story in 6+ sentences, using participle clauses to sound concise and fluent.
In This Lesson
A Quick Recap of Relative Clauses
A relative clause adds information about a noun using a relative pronoun β who, which, that, whose, where, when. You met these at B1. There are two kinds, and telling them apart matters for everything that follows.
| Defining | Non-defining | |
|---|---|---|
| Job | identifies which one β essential | adds extra info β non-essential |
| Commas? | No commas | Commas (or dashes/parentheses) |
| that? | Can use that | Cannot use that |
| Example | The woman who lives next door is a doctor. | My sister, who lives next door, is a doctor. |
β οΈ Quick reminder: In a defining clause you can drop the pronoun when it's the object β "the movie (that) we watched." You cannot drop it in a non-defining clause. Hold on to this distinction; reducing clauses works differently for each.
That's the review. The real work of this lesson is what comes next: making these clauses shorter.
π§ Mindset
Nothing here is brand-new vocabulary or a new tense β you already own -ing forms and past participles from the continuous and the passive. B2 is about compression: saying the same thing with fewer, better-chosen words. If reducing a clause feels like a puzzle at first, that's exactly right β you're learning to see the same sentence from two angles at once. That flexibility is a skill, and it grows every time you try it. π±
Reducing Clauses: The Core Move
Here's the whole idea in one line: in a defining relative clause, you can often delete the relative pronoun and the verb be, leaving a participle. What kind of participle depends on whether the original verb was active or passive.
Active β Present Participle (-ing)
If the relative clause describes something the noun does (active), reduce it to an -ing participle.
| Full relative clause | Reduced participle clause |
|---|---|
| The man who is standing there is my uncle. | The man standing there is my uncle. |
| The woman who lives next door is a doctor. | The woman living next door is a doctor. |
| Anyone who wants a ticket must line up here. | Anyone wanting a ticket must line up here. |
| The train that leaves at noon is full. | The train leaving at noon is full. |
π‘ Notice the two cases
When the clause is be + -ing ("who is standing"), you simply drop who is. When it's a simple-tense verb ("who lives", "that leaves"), you change that verb itself into the -ing form. Both routes land on the same clean result: a bare -ing participle.
Passive β Past Participle (-ed / 3rd form)
If the relative clause is passive β something is done to the noun β reduce it to a past participle (the 3rd form: written, sold, built, made).
| Full relative clause | Reduced participle clause |
|---|---|
| The letter which was written by John arrived late. | The letter written by John arrived late. |
| The books that are sold here are second-hand. | The books sold here are second-hand. |
| The bridge which was built in 1890 is closed. | The bridge built in 1890 is closed. |
| Products that are made locally cost more. | Products made locally cost more. |
β οΈ The one test that always works
Ask: does the noun DO the action, or RECEIVE it? If it does it β -ing ("the man standing" β he stands). If it receives it β past participle ("the letter written" β someone wrote it). Get this right and you'll never confuse the two forms. And remember β this reduction works on defining clauses; keep the commas (and the full pronoun) for non-defining ones in careful writing.

Combining Ideas & Showing Relationships
Participle clauses do more than trim relative clauses. They can also join two sentences into one, quietly signaling time, sequence or reason β without a linking word like because or when. This is the move that makes prose flow.
Time & Sequence
A participle clause can show that two actions happen at the same time, or one after another.
| Two sentences | Combined with a participle | Meaning |
|---|---|---|
| I was walking home. I saw an accident. | Walking home, I saw an accident. | = While I was walking (same time) |
| She finished work. Then she went home. | After finishing work, she went home. | = sequence (after + -ing) |
| He opened the door. He turned on the light. | Opening the door, he turned on the light. | = two near-simultaneous actions |
Reason (= because)
A participle clause at the start of a sentence very often means because β it gives the reason for the main action. This works with both -ing and negative forms.
| Full clause with because | Participle clause |
|---|---|
| Because he felt tired, he went to bed. | Feeling tired, he went to bed. |
| Because we didn't know the way, we got lost. | Not knowing the way, we got lost. |
| Because it is made of glass, it breaks easily. | Made of glass, it breaks easily. |
π‘ Negatives go in front
To make a participle clause negative, put not before it: Not knowing what to say, she stayed silent. Not having eaten all day, he was starving. Simple placement, natural result.
Perfect Participle β an Earlier Action
When you want to stress that one action was completely finished before the next, use the perfect participle: having + past participle. It's the participle equivalent of the past perfect.
| Full version | Perfect participle |
|---|---|
| After she had finished, she left. | Having finished, she left. |
| Because they had lost the map, they turned back. | Having lost the map, they turned back. |
| After I had read the report, I emailed the team. | Having read the report, I emailed the team. |
Here they all are, woven into one short narrative:
"Having arrived early, I found a cafΓ© near the office. Sitting by the window, I watched the street slowly fill with commuters. Not wanting to seem nervous, I ordered a coffee and opened my notes. The building opposite, built in the 1920s and recently restored, looked far grander than I'd expected."
Perfect participle (having arrived) Β· present participle for background (sitting) Β· reason (not wanting) Β· reduced passive relative clause (built).
The Subject Rule (Dangling Participles)
This is the single most important rule in the lesson β and the source of a classic, telling error. Here it is:
β οΈ KEY RULE: same subject
The subject of the participle must be the same as the subject of the main clause. The person or thing doing the -ing action must be the one the main sentence is about. When it isn't, you get a dangling participle β often accidentally hilarious.
| Sentence | Who is "walking"? | Verdict |
|---|---|---|
| Walking home, the rain started. | Grammatically, the rain β but rain can't walk! | β Dangling |
| Walking home, I got caught in the rain. | I β the same subject as the main clause. | β Correct |
| Reading the letter, tears filled her eyes. | Grammatically tears β tears don't read! | β Dangling |
| Reading the letter, she began to cry. | She β she reads and she cries. | β Correct |
The fix is always the same: make sure the noun right after the comma is the one actually doing the participle's action. If it isn't, either change the main-clause subject or expand the participle back into a full clause ("While I was walking home, the rain started" is perfectly fine).
β οΈ How to catch it yourself
After writing a participle clause, glance at the very next noun. Ask: "Is this the thing doing the -ing?" If the honest answer is no, you've found a dangling participle before your reader did.

π‘ Where participle clauses belong
Participle clauses are more common in writing β and especially in formal, literary and descriptive style β than in casual speech. In everyday conversation, most people still say "the man who's standing there." But in a report, a story, a description or an essay, participle clauses make your prose tighter and more sophisticated. Use them to polish written work; don't force them into chatty speech, where they can sound stiff.
Keep these sentence-starters handy β they'll get participle clauses flowing in your own writing:
- Feeling confident, she raised her hand.
- Written in 1998, the novel still feels modern.
- Standing there on the platform, he waved until the train disappeared.
- Having lost the match, the team stayed silent.
- Surrounded by forest, the village feels remote.
- Not having a plan, we improvised.
π Hear It & Repeat β Model Sentences
Listen to each model sentence, then say it back. Use the π§ Audio control (bottom-right) to choose a UK or US voice and slow the speed down. Notice how the full relative clauses get trimmed down to lean participle phrases.
- The woman standing by the window is the architect who designed the museum.
- Shocked by the news, the whole team fell completely silent.
- Anyone wanting a refund should keep the original receipt.
- The car parked outside the office has been there all week.
- Having finished the interviews, the reporter began writing her article.
Practice & Project
ποΈ Exercise 1: Reduce the relative clause
Objective: Rewrite each sentence, reducing the relative clause to a participle clause (active β -ing, passive β past participle).
- The people who are waiting outside look cold.
- The email which was sent yesterday never arrived.
- Any student who fails the test can retake it.
- The paintings that were stolen in 2004 were finally found.
- The road that connects the two towns is closed.
β Answer
1. The people waiting outside look cold. Β· 2. The email sent yesterday never arrived. Β· 3. Any student failing the test can retake it. Β· 4. The paintings stolen in 2004 were finally found. Β· 5. The road connecting the two towns is closed.
ποΈ Exercise 2: Combine with a participle clause
Objective: Join each pair into one sentence using a participle clause showing reason or time. (More than one good answer is often possible.)
- She didn't feel well. She stayed at home. (reason)
- He was driving to work. He heard the news on the radio. (time)
- They had finished dinner. They went for a walk. (sequence β use a perfect participle)
- I didn't know his number. I couldn't call him. (reason, negative)
β Answer
1. Not feeling well, she stayed at home. Β· 2. Driving to work, he heard the news on the radio. Β· 3. Having finished dinner, they went for a walk. Β· 4. Not knowing his number, I couldn't call him.
ποΈ Exercise 3: Fix the dangling participle
Objective: Each sentence has a dangling participle β the subject doesn't match. Rewrite it so the participle's subject and the main clause agree.
- Looking out of the window, the mountains were beautiful.
- Having eaten too much, the meal made me sleepy.
- Running for the bus, my bag fell open.
β Answer
Model corrections (yours may differ but must fix the subject):
1. Looking out of the window, I thought the mountains were beautiful. (Or: While I looked out of the window, the mountains were beautiful.) Β· 2. Having eaten too much, I felt sleepy. Β· 3. Running for the bus, I felt my bag fall open. (Or: As I ran for the bus, my bag fell open.)
π― Your Project: Describe It Concisely
Write β then, if you can, read aloud β a short description of one of these: a scene (a place, real or imagined), a process (how something is made or done), or a person's story (a mini-biography). Your goal: 6+ sentences, at least four of them using participle clauses.
- (3 min) Choose your subject and jot down 6β8 plain facts about it in simple sentences.
- (4 min) Rewrite: reduce any relative clauses to participles, and combine pairs of facts using -ing, -ed or having + pp for time, reason and sequence.
- (3 min) Check every participle clause: does its subject match the main clause? Hunt for danglers.
- (3 min) β Solo: Read your description into your phone's recorder; listen for flow. Partner/group: swap descriptions and challenge each other to find any dangling participle or any clause that would read better reduced (or un-reduced).
Mini-model (a scene): "Perched on a hill, the old town looks down on the river. Walking up its narrow streets, you pass houses painted in faded pastels. Built centuries ago, the cathedral still dominates the square. Having climbed to the top, visitors are rewarded with a view stretching to the sea."
β Project Completion Checklist
- β My description has at least 6 sentences
- β At least 4 use a participle clause
- β I used at least one reduced passive (past participle) clause
- β I used at least one clause showing reason or time
- β I checked every participle for a matching subject (no danglers)

Tips & Common Mistakes
β Do's
- Ask "does the noun do it or receive it?" to choose between -ing and the past participle.
- Use participle clauses to tighten written descriptions and reports β that's where they shine.
- Reach for having + past participle when one action clearly finished before the next.
- After every participle clause, check the next noun is the one doing the action.
β Common Mistakes
β οΈ Watch Out
- Dangling participles: "Reading the paper, the dog barked" β β the dog wasn't reading. Match the subject.
- Wrong participle for the voice: "The books selling here" β (the books don't sell β they're sold) β "The books sold here" β .
- Reducing non-defining clauses carelessly: in careful writing, keep the commas and full pronoun where the info is just extra ("My car, which was bought last year, β¦").
- Overusing them in speech: "the man standing there" is natural; a whole spoken paragraph of participle clauses sounds bookish.
π Learning Journal
Keep your learning journal going. After this lesson, take a few minutes to write down:
- Key concepts you learned
- Things that clicked for you
- Questions or confusion points to revisit
- Ideas you want to try
- Your progress and feelings about reaching B2
βοΈ This lesson's prompt: Take three sentences from something you wrote recently (an email, a message, a note) that use who, which or that. Reduce each to a participle clause. Then write one honest line: did the reduced version sound better, or was the full clause clearer? Learning when not to reduce is as much a B2 skill as learning how.
π Lesson Summary
π Key Takeaways
- Defining vs non-defining: defining clauses identify (no commas); non-defining ones add extra info (commas). Reduction mainly targets defining clauses.
- Active β -ing: "the woman who lives here" β "the woman living here."
- Passive β past participle: "the letter which was written" β "the letter written."
- Participle clauses also show time, reason and sequence β including having + pp for an earlier action.
- The subject must match: mismatched subjects create a dangling participle.
- They belong mostly in writing β concise, formal, descriptive prose.
π What You've Accomplished
You've learned to see one sentence two ways β full and reduced β and to choose the tighter version on purpose. That's a real writer's skill: not just being correct, but being economical. Your descriptions, reports and stories will now read with a fluency that careful learners rarely reach. π
β Common Questions at This Stage
Can I reduce a non-defining relative clause too?
Sometimes, especially in literary or journalistic writing ("My uncle, living abroad for years, rarely visited"), but it's less common and easy to overdo. In everyday careful writing, keep non-defining clauses full β commas and pronoun intact. Focus your reducing on defining clauses, where it's most natural.
How do I know whether to use -ing or having + pp?
Use plain -ing for actions happening at the same time as the main clause ("Walking home, I sawβ¦"). Use having + past participle when the first action is clearly finished before the second ("Having walked home, I made dinner"). If the sequence matters, the perfect participle makes it explicit.
Is "the man standing there" really more correct than "the man who is standing there"?
Neither is more correct β both are perfectly grammatical. The reduced version is simply more concise, and often preferred in writing. Think of reduction as a stylistic tool for polish, not a correction of an error.
π Looking Ahead
You've been compressing your own sentences. Next you'll learn to relay other people's words with precision. In Lesson 3.3, Reporting Verbs & Patterns, you'll move beyond "he said thatβ¦" to a rich toolkit β admit, suggest, deny, warn, promise β each with its own grammar pattern, so you can report speech with exactly the right shade of meaning.
β Before the Next Lesson
- Find three signs, labels or captions in English and spot the reduced clauses ("Made inβ¦", "Handle with care", "Products sold here").
- Rewrite a paragraph of your own, reducing at least four clauses to participles.
- Write your Learning Journal entry for this lesson.
π Encouragement for the Journey
Concision is a quiet superpower. Anyone can add words; a confident writer knows which ones to remove β and this lesson handed you a precise tool for doing exactly that. Every time you turn "the house that was built by my grandfather" into "the house built by my grandfather," you're writing like someone who owns the language. Onward to Lesson 3.3! π
