Grammar: Advanced Relative Clauses

Move the preposition to the front, count with of whom / of which, and write with the polish of a formal report.

One structure, a far more precise voice

You already build simple relative clauses: the man who called, the book that I read. At B2 the goal is control in a formal, academic register — the English of essays, reports and serious articles. Three moves make the difference: putting the preposition before whom / which, using a quantifier + of whom / of which, and handling non-defining clauses with confidence.

These structures let you pack precise information into a single, elegant sentence, without the loose feel of everyday speech. Compare the two versions below and notice how the second one sounds measured and professional.

  • The colleague who I spoke to was very helpful.Neutral / informal → preposition at the end.
  • The colleague to whom I spoke was very helpful.Formal register → preposition + whom.
  • We met ten investors, and many of them withdrew.Two clauses joined loosely.
  • We met ten investors, many of whom withdrew.One clause → quantifier + of whom.

1. The building blocks (relative pronouns)

Fix the basic pronouns first, because every advanced pattern grows from them. Whom is the object form of who, and it is the form you must use after a preposition.

PronounRefers toExample
whoa person (subject)the analyst who wrote the report
whoma person (object / after a preposition)the analyst to whom we replied
whicha thing (and after a preposition)the fund from which it came
whosepossession (people or things)the firm whose shares fell
where / whena place / a timethe year when she resigned
Key point
  • After a preposition, English never uses who or that: use whom for people and which for things.
  • the person to whom I wrote ✓ — the person to who I wrote ✗ — the person to that I wrote

2. Preposition + whom / which (the formal move)

In everyday English the preposition often sits at the end: the way which we did it in → usually the way we did it in. In formal writing you lift the preposition to the front, in front of whom (people) or which (things). The clause instantly sounds more academic.

Informal (end)Formal (front)Meaning
the manager I reported tothe manager to whom I reportedbir kişiye rapor verdim
the account we paid it fromthe account from which we paidbir hesaptan ödedik
the method he worked it out withthe method with which he workedbir yöntemle çalıştı
the way she solved it inthe way in which she solved itbir biçimde çözdü
Golden rule
  • Preposition + whom for people, preposition + which for things. Never move a preposition in front of who or that.
  • The very common phrase the way in which means simply "how": the way in which the law works = how the law works.

3. Quantifier + of whom / of which (counting inside a clause)

When you want to say something about part of a group, join the two ideas with a quantifier + of whom (people) or of which (things). This always appears in a non-defining clause, so it needs a comma before it.

Two sentencesOne clause
I have three sisters. All of them are doctors.I have three sisters, all of whom are doctors.
She wrote fifty essays. Some of them were published.She wrote fifty essays, some of which were published.
They offered two options. Neither of them worked.They offered two options, neither of which worked.
We hired ten staff. Both of them stayed.We hired two staff, both of whom stayed.
B2 subtlety
  • Common quantifiers here: all, both, many, most, some, none, several, neither, half, a few, one + of whom / of which.
  • Write of which, not which of: a report, some of which was secret ✓ — a report, some which of was secret

4. Whose (possession, people and things)

Whose replaces a possessive (his, her, its, their). Many learners think it is only for people, but it works for things and organisations too, which is very useful in formal writing.

  • She is the author whose novels I admire.People → her novels → whose novels.
  • It is a company whose profits have collapsed.A thing / organisation → its profits → whose profits.
  • The building, whose roof was damaged, has been repaired.Non-defining → commas → whose roof.
Watch out
  • Do not confuse whose (possessive) with who's (= who is): the writer whose book won ✓ — the writer who's book won

5. Defining vs non-defining (the comma decides)

A defining clause tells you which one — it is essential, so it takes no commas. A non-defining clause adds extra, optional information between commas. The choice changes both punctuation and the pronoun you may use.

Defining (no commas)Non-defining (commas)
Purposeidentifies which one (essential)adds extra detail (optional)
ExampleThe report that she wrote is on my desk.The report, which she wrote overnight, is excellent.
"that"?allowed (that / which / who)never "that" → use which / whom
Golden rule
  • In a non-defining clause, never use that, and never drop the pronoun: Ankara, which I love, is growing ✓ — Ankara, that I love, is growing
  • Prepositional and quantifier clauses (to whom, many of which) follow the same comma rule as the clause type they belong to.

6. Reduced relative clauses (a shorter option)

You can often drop the relative pronoun and the verb "be", leaving just a participle. This makes writing lighter, and it is common in formal descriptions.

Full clauseReduced clause
the man who is standing therethe man standing there
the bridge which was built in 1890the bridge built in 1890
the people who were invitedthe people invited
Note
  • Use the -ing form for active ideas (the woman chairing the meeting) and the -ed / V3 form for passive ones (the decision taken yesterday).

7. Common mistakes (✗ / ✓)

These are the errors B2 students still make with relative clauses. Check your own writing against every row.

Wrong ✗Right ✓Why?
The client to who I spoke complained.The client to whom I spoke complained.after a preposition, use whom, not who.
Berlin, that I love, is a great city.Berlin, which I love, is a great city.no "that" in a non-defining clause.
a report, some which of was secreta report, some of which was secretthe order is quantifier + of + which.
the fund which the money came from itthe fund from which the money camedo not keep the extra "it" / "from".
the writer who's book won a prizethe writer whose book won a prizewhose = possessive; who's = who is.

8. Putting it together (Model Dialogue)

Two researchers discuss a grant application. Read it twice and watch the advanced structures: preposition + whom / which, quantifier + of whom, whose, and non-defining clauses set off by commas.

A:Have you heard from the board to whom we submitted the proposal?Formal register → preposition + whom.
B:Yes. There are seven members, most of whom support us.Quantifier + of whom in a non-defining clause.
A:And the foundation whose grant we need?Possessive for an organisation → whose grant.
B:They sent conditions, some of which are quite strict.Quantifier + of which for things.
A:What about the account from which the money is paid?Preposition + which.
B:That is the one on which everything depends. The report, which I finished last night, explains it all.Preposition + which, then a non-defining clause with commas.
Test yourself
  • Rewrite "the board to whom we submitted it" with the preposition at the end. (the board we submitted it to)
  • Why is there a comma before "most of whom"? (It is a non-defining clause adding extra information.)
  • Turn "a foundation whose grant we need" into two sentences. (There is a foundation. We need its grant.)

Reading: The Woman to Whom a Museum Owes Everything

Read the text, then answer the questions.

Before You Read (Okumadan Önce)

Good readers prepare before they start. Before you read, think about these three questions (you do not need to write the answers):

  • Think of an institution — a school, a library, a museum — that matters to your town. Who built it?
  • The text is written in a formal register. Which relative structures (to whom, of which, whose) do you expect to meet?
  • The title says the museum "owes everything" to one woman. Guess: what obstacle did she overcome?
How to read
  • First read: read quickly, without stopping. Get the general idea; you do not need every word.
  • Second read: read the questions, then search the text. Notice each relative clause — to whom, many of whom, on which, whose — and ask what it is adding.

Words to spot (from the Speaking section): institution · legacy · distinguished · prominent · patron · oversee · recognition · devote

MUSEUM founder
A national museum saved by one determined founder.
The Woman to Whom a Museum Owes Everything

Few visitors to the National Museum of Anatolia realise how close it came to never opening. The institution, whose collection now attracts millions, was almost abandoned in the 1970s. The person to whom it owes its survival is Dr Nermin Aksoy, a distinguished archaeologist whose determination proved decisive.

To understand the crisis, one must picture the Turkey of that era, in which cultural spending was among the first things to be cut whenever budgets grew tight. The old exhibition hall, whose roof had begun to leak, held crates of artefacts that had waited years to be catalogued. Officials to whom the matter was referred tended to shrug; a museum, in their view, was a luxury for which the treasury simply had no money. Boxes of pottery, coins and weathered inscriptions, most of which had been excavated decades earlier, sat forgotten in damp storerooms where no visitor could ever see them. Some of the finest pieces, the value of which no one had even bothered to measure, were wrapped in old newspaper and stacked on wooden shelves. It was against this discouraging background, in a decade during which many similar projects were quietly shelved, that Aksoy, then in her early forties, decided the collection deserved a permanent home worthy of the civilisations it represented.

Aksoy had trained under several prominent scholars, many of whom doubted that a national museum could ever be funded. Although the odds were against her, she assembled a committee of thirty experts, some of whom later became ministers. The plan on which they eventually agreed was ambitious; moreover, it was expensive. Her rivals wanted a modest gallery, whereas Aksoy insisted on a single building in which the entire history of the region could be displayed.

The committee, whose meetings often lasted late into the night, was far from united. There were members for whom caution was everything, and others who shared Aksoy's appetite for risk. One senior colleague, whose scepticism she never quite forgave, argued that a grand museum would collapse under its own running costs, and warned that the public for whom it was intended would soon lose interest. Aksoy listened to every objection, yet the argument to which she always returned was disarmingly simple: a nation that hides its past cannot truly be proud of it. She travelled from city to city, giving lectures in draughty halls to audiences some of whom had never once set foot in a museum. She wrote letters to editors, to ministers, and to anyone whose signature might carry weight. Slowly the mood began to shift, and journalists who had earlier ignored the scheme started to write about the woman whose stubbornness refused to let it die.

The funding, without which nothing would have happened, came from an unexpected source. A private foundation, the director of which had studied with Aksoy, offered a substantial grant. The conditions to which the money was attached were strict; nevertheless, Aksoy accepted them, since she had no alternative.

The negotiations through which the grant was finally secured were exhausting. The foundation's trustees, to whom every figure had to be justified, insisted on a detailed plan for the decades to come. 'We admire your vision,' one trustee told her across a long table, 'but a building whose upkeep no one can afford is not a gift; it is a burden.' Aksoy, for whom failure was by now unthinkable, spent months preparing budgets, forecasts and maintenance schedules, many of which she drafted herself late at night. The clause on which the trustees insisted most firmly required the museum to remain free to schoolchildren for ever — a condition to which Aksoy agreed without a moment's hesitation, since it matched her own deepest beliefs about who a museum is really for. Only when every last document had been signed, and every promise on which the money depended had been made, did she allow herself to believe that the museum about which she had dreamed for so long might truly rise.

The architect chosen for the project, whose earlier designs had won awards, produced a building admired to this day. However, the galleries were not finished on time; therefore, the opening was delayed by a year. Each of the halls, all of which follow a clear theme, guides visitors through five thousand years. Aksoy personally oversaw every stage and devoted a decade to the endeavour.

Construction became a saga in its own right. The site on which the building rose had once been an olive grove, beneath which archaeologists soon uncovered the remains of an ancient wall. The work, which everyone had expected to take three years, halted while these unforeseen finds were carefully recorded — a delay that, ironically, enriched the very collection the museum would one day house. The architect, with whom Aksoy corresponded almost daily, redesigned an entire wing so that the ancient wall could be shown where it stood, protected behind glass through which visitors now gaze in wonder. There were months during which funds ran alarmingly low, and moments at which even Aksoy quietly wondered whether the doubters had been right. Yet when the doors at last swung open, the crowds for whom she had fought poured inside, and the same newspapers that had once dismissed her printed her photograph across their front pages.

Aksoy, who never sought recognition, retired quietly in 1995. 'A museum,' she once said, 'is not the walls within which objects sit; it is the people for whom those objects still speak.' Her portrait now hangs by the entrance, yet few know her name — a quiet legacy of which she would surely have approved.

Today the National Museum of Anatolia is a place to which scholars travel from every continent. Its galleries, in which schoolchildren sketch statues older than any empire, welcome more people in a single week than the old hall had seen in an entire year. The guides who lead the daily tours still repeat the story of the archaeologist without whom none of it would exist, and the words with which she ended her career — about walls, objects and the people for whom those objects speak — are engraved on a plaque beside her portrait. Visitors for whom the name Aksoy means nothing pause there all the same, drawn by a face whose quiet determination somehow still reaches across the years, and they leave knowing a little more about the woman to whom the museum owes everything.

Writing: A Portrait of Influence

Write and submit your paragraph; your teacher will review it.

Connectors that sound B2 (Linking Words)

At B1 you linked ideas with and, but, so, because. At B2 you sound noticeably more advanced when you use formal, precise connectors. Combine these with the relative clauses of this unit and your writing will read like a polished profile.

ConnectorUse it to...Example
moreoveradd a stronger, extra pointShe was a fine teacher. Moreover, she was a patron of the arts.
thereforeshow a logical resultNo one would fund it; therefore, she funded it herself.
whereascontrast two ideas directlyOthers sought fame, whereas she sought no recognition.
neverthelesssay "in spite of that"The task was huge. Nevertheless, she persevered.
althoughconcede a point inside one sentenceAlthough she avoided the spotlight, her legacy is famous.
howevercontrast between two sentencesI admire many people. However, one stands out.

See the difference — the same facts, written two ways:

Basic linking ✗Confident B2 writing ✓
My grandmother was a teacher. She taught many students. They still respect her. She never wanted fame. I admire her. My grandmother, whose patience I still remember, taught hundreds of students, many of whom still respect her. Although she never sought fame, her influence was enormous; therefore, she is the person to whom I owe the most.
Rule
  • Use at least 3 different B2 connectors from the table. Do not write sentence by sentence; connect your ideas.
  • Moreover, Therefore, However, Nevertheless usually start a sentence and take a comma: "However, one stands out."

Paragraph structure (Paragraph Structure)

A "portrait of influence" paragraph has three parts. The skeleton stays the same — you change the content, not the structure:

PartWhat to writeExample
1. OpeningIntroduce the person or institution with a non-defining clauseThe person to whom I owe the most is my old physics teacher, whose passion was contagious.
2. BodyExplain the influence. Use preposition + whom/which, quantifier + of whom/which and whose, linked with B2 connectors.He gave us projects, most of which seemed impossible; nevertheless, we finished them.
3. ClosingA final comment about the lasting effect or legacyIt is a legacy for which I remain deeply grateful.

Task (Görev)

Write about a person, place or institution that has shaped you, your studies or your community. Describe the influence, not just the facts. Use the relative clauses of this unit.

WHAT TO INCLUDE

  • an opening sentence introducing the person/place with a non-defining clause (commas)
  • at least two examples of preposition + whom / which (to whom, in which, on which...)
  • at least one quantifier + of whom / of which (many of whom, some of which...)
  • at least one use of whose for a person or an institution
  • a closing sentence about the lasting legacy or effect
  • at least 3 B2 connectors: moreover, therefore, whereas, nevertheless, although, however
  • at least 4 words from the Speaking section (institution, legacy, distinguished, prominent, patron, devote, esteemed, recognition)

Sample Answer (~186 words) The person to whom I owe the most is my old literature teacher, Mrs Yalçın, whose passion for books completely changed me. She taught at a small state school, an institution whose library held barely a thousand volumes; nevertheless, she treated every one of them as a treasure.

In her lessons, most of which I still remember vividly, she never simply explained a text. Instead, she asked questions to which there were no easy answers. She lent me novels, several of which I would never have discovered alone. Although she was a distinguished scholar, she devoted her evenings to slow readers like me.

Other teachers wanted quiet, obedient classes, whereas Mrs Yalçın wanted argument and doubt. Therefore, her classroom was the one place in which I felt truly alive. She never received public recognition, and she retired without ceremony.

Today I teach in the same town, and I try to pass on the legacy for which I remain so grateful. She is the mentor whose voice I still hear whenever I open a difficult book.
