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 teacher who I spoke to was very helpful.Neutral / informal → preposition at the end.
  • The teacher to whom I spoke was very helpful.Formal register → preposition + whom.
  • We invited ten friends, and many of them left early.Two clauses joined loosely.
  • We invited ten friends, many of whom left early.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 girl who wrote the story
whoma person (object / after a preposition)the girl to whom we replied
whicha thing (and after a preposition)the box from which it came
whosepossession (people or things)the team whose captain left
where / whena place / a timethe year when she moved away
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 teacher I spoke tothe teacher to whom I spokebir öğretmenle konuştum
the box we took it fromthe box from which we took itbir kutudan aldık
the tool he fixed it withthe tool with which he fixed itbir aletle tamir etti
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 game works = how the game 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 cousins. All of them play football.I have three cousins, all of whom play football.
She drew fifty pictures. Some of them were framed.She drew fifty pictures, some of which were framed.
They tried two plans. Neither of them worked.They tried two plans, neither of which worked.
We picked two goalkeepers. Both of them stayed.We picked two goalkeepers, 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 diary, some of which was secret ✓ — a diary, 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 writer whose stories I love.People → her stories → whose stories.
  • It is a team whose scores have collapsed.A thing / group → its scores → whose scores.
  • The school, 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 story that she wrote is on my desk.The story, which she wrote last night, 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: My town, which I love, is growing ✓ — My town, 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 girl leading the team) and the -ed / V3 form for passive ones (the photo 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 boy to who I spoke complained.The boy 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 diary, some which of was secreta diary, some of which was secretthe order is quantifier + of + which.
the box which the marbles came from itthe box from which the marbles 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 friends discuss the school science fair. 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 teachers to whom we gave our project?Formal register → preposition + whom.
B:Yes. There are seven judges, most of whom like our idea.Quantifier + of whom in a non-defining clause.
A:And the club whose prize we want?Possessive for a group → whose prize.
B:They sent some rules, some of which are quite strict.Quantifier + of which for things.
A:What about the cupboard from which we borrow the tools?Preposition + which.
B:That is the one on which everything depends. The poster, which I finished last night, explains it all.Preposition + which, then a non-defining clause with commas.
Test yourself
  • Rewrite "the teachers to whom we gave it" with the preposition at the end. (the teachers we gave it to)
  • Why is there a comma before "most of whom"? (It is a non-defining clause adding extra information.)
  • Turn "a club whose prize we want" into two sentences. (There is a club. We want its prize.)

Reading: The Teacher to Whom a Library 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 library "owes everything" to one teacher. 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

LIBRARY teacher
A school library saved by one determined teacher.
The Teacher to Whom a Library Owes Everything

Few children at Maple Hill School realise how close their library came to never opening. The library, whose shelves now welcome every class in the school, was almost abandoned in the 1970s. The person to whom it owes its survival is Miss Deniz Aktaş, a dedicated teacher whose determination proved decisive.

To understand the problem, one must picture the school of that time, in which spending on books was among the first things to be cut whenever money grew tight. The old reading room, whose roof had begun to leak, held boxes of donated books that had waited years to be sorted. The head teachers to whom the matter was mentioned tended to shrug; a library, in their view, was a luxury for which the school simply had no money. Boxes of stories, atlases and picture books, most of which had been given years earlier, sat forgotten in a damp storeroom where no child could ever reach them. Some of the finest books, the value of which no one had even bothered to guess, were wrapped in old newspaper and stacked on broken shelves. It was against this discouraging background, in a decade during which many similar ideas were quietly dropped, that Miss Aktaş, then a young teacher, decided the school deserved a proper library worthy of the pupils who filled its classrooms.

Miss Aktaş had learned from several experienced teachers, many of whom doubted that a real school library could ever be built. Although the odds were against her, she gathered a team of thirty helpers, some of whom later became teachers themselves. The plan on which they eventually agreed was ambitious; moreover, it was expensive. Other teachers wanted a small shelf of books in each classroom, whereas Miss Aktaş insisted on a single bright room in which the whole world of books could be kept together.

The team, whose meetings often ran late into the evening, was far from united. There were helpers for whom caution was everything, and others who shared Miss Aktaş's love of bold ideas. One older teacher, whose doubts she never quite forgave, argued that a big library would cost too much to keep clean and warm, and warned that the children for whom it was intended would soon lose interest. Miss Aktaş listened to every objection, yet the argument to which she always returned was wonderfully simple: a school that hides its books cannot teach children to love reading. She went from classroom to classroom, giving talks to pupils some of whom had never once borrowed a book. She wrote letters to parents, to the mayor, and to anyone whose signature might help. Slowly the mood began to change, and the local paper, which had earlier ignored the idea, started to write about the teacher whose stubbornness refused to let it die.

The money, without which nothing would have happened, came from an unexpected source. A small local charity, the founder of which had once been Miss Aktaş's own teacher, offered a generous donation. The conditions to which the money was attached were strict; nevertheless, Miss Aktaş accepted them, since she had no alternative.

The talks through which the donation was finally agreed were exhausting. The charity's trustees, to whom every cost had to be explained, asked for a careful plan for the years ahead. 'We admire your dream,' one trustee told her across a long table, 'but a library that no one can afford to keep is not a gift; it is a burden.' Miss Aktaş, for whom failure was by now unthinkable, spent months preparing lists, budgets and repair plans, many of which she wrote out herself late at night. The rule on which the trustees insisted most firmly was that the library must stay free to every child for ever — a condition to which Miss Aktaş agreed without a moment's hesitation, since it matched her own deepest belief about who a library is really for. Only when every last form had been signed, and every promise on which the money depended had been made, did she allow herself to believe that the library about which she had dreamed for so long might truly open.

The carpenter chosen for the project, whose earlier work had won local prizes, built shelves admired to this day. However, the shelves were not finished on time; therefore, the opening was delayed by a year. Each of the sections, all of which follow a clear theme, guides readers from picture books to thick adventures. Miss Aktaş personally oversaw every stage and devoted a decade to the endeavour.

Building the library became a small adventure in itself. The corner on which the new room rose had once been a dusty yard, beneath which the builders soon found the old foundations of a garden wall. The work, which everyone had expected to take a single summer, stopped while these surprises were carefully recorded — a delay that, oddly, gave the school its own little piece of history to display. The carpenter, with whom Miss Aktaş talked almost every day, redesigned a whole corner so that the old wall could be shown where it stood, protected behind glass through which children now peer in wonder. There were months during which the funds ran alarmingly low, and moments at which even Miss Aktaş quietly wondered whether the doubters had been right. Yet when the doors at last swung open, the children for whom she had fought poured inside, and the same paper that had once dismissed her printed her photograph on its front page.

Miss Aktaş, who never sought recognition, retired quietly in 1995. 'A library,' she once said, 'is not the walls within which books sit; it is the children for whom those books still speak.' Her photograph now hangs by the door, yet few pupils know her name — a quiet legacy of which she would surely have approved.

Today the Maple Hill library is a place to which children come from every class, every single day. Its shelves, among which pupils sketch, read and whisper about stories, welcome more visitors in a single week than the old reading room had seen in a whole year. The older pupils who lead the youngest ones to their first book still repeat the story of the teacher without whom none of it would exist, and the words with which she ended her years at the school — about walls, books and the children for whom those books speak — are painted on a small sign beside her photograph. Children for whom the name Aktaş 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 teacher to whom the library 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 our chess club.
thereforeshow a logical resultNo one would help; therefore, she built the treehouse 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."

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, whenever I open a difficult book, I try to read the way she taught me, and I remember the legacy for which I remain so grateful. She is the mentor whose voice I still hear whenever a story feels too hard.
