Relative Clauses

English Grammar Tutorial

Lesson 19 of 19

1. What Is a Relative Clause?

A relative clause gives extra information about a person, thing, place, or time. It often begins with a relative pronoun or relative adverb.

Hindi meaning: Relative clause किसी व्यक्ति, वस्तु, स्थान या समय के बारे में अतिरिक्त जानकारी देता है।

Example: The girl who is wearing a red dress is my sister.

Hindi: लाल पोशाक पहने हुई लड़की मेरी बहन है।

Here, “who is wearing a red dress” tells us which girl we mean.

2. Relative Pronouns

WordUsed forExampleHindi meaning
whoPeople (subject)The man who called you is here.जिस आदमी ने तुम्हें फोन किया, वह यहाँ है।
whomPeople (object; formal)The woman whom I met was kind.जिस महिला से मैं मिला, वह दयालु थी।
whosePossessionThe boy whose bag is missing is upset.जिस लड़के का बैग गायब है, वह परेशान है।
whichThings and animalsThe book which I bought is useful.जो किताब मैंने खरीदी, वह उपयोगी है।
thatPeople or things in defining clausesThe phone that I bought works well.जो फोन मैंने खरीदा, वह अच्छी तरह काम करता है।
Tip: In everyday English, who is often used instead of whom. Do not use that in a non-defining relative clause, which adds extra information between commas.

3. Relative Adverbs: Where, When, and Why

WordUsed forExampleHindi meaning
wherePlaceThis is the school where I studied.यह वह स्कूल है जहाँ मैंने पढ़ाई की।
whenTimeI remember the day when we first met.मुझे वह दिन याद है जब हम पहली बार मिले थे।
whyReasonTell me the reason why you are late.मुझे वह कारण बताओ कि तुम देर से क्यों आए।

4. Defining Relative Clauses

A defining relative clause gives essential information. Without it, we may not know exactly which person or thing is meant. Do not put commas around it.

Example: The student who scored the highest marks received a prize.
Hindi: जिस विद्यार्थी ने सबसे अधिक अंक प्राप्त किए, उसे पुरस्कार मिला।
  • The woman who lives next door is a doctor.
  • The laptop that I use is very old.
  • The people who work here are friendly.
  • The shop where I buy books is closed today.

When the relative pronoun is the object, it can often be omitted: “The movie (that) we watched was exciting.”

5. Non-Defining Relative Clauses

A non-defining relative clause adds extra information that is not needed to identify the person or thing. Use commas around it.

ExampleExplanation
My brother, who lives in Delhi, is a teacher.“who lives in Delhi” adds extra information.
Delhi, which is the capital of India, is a large city.The clause gives additional information about Delhi.
My phone, which I bought last year, still works well.“which I bought last year” is extra information.
Do not use that in a non-defining relative clause. Use who for people or which for things, with commas.

6. Using Whose and Whom

Whose — possession
  • I know a student whose father is a doctor.
  • The woman whose car was stolen called the police.
  • He is the writer whose books I enjoy.
Whom — object (more formal)
  • The person whom you called is my uncle.
  • The teacher to whom I spoke was helpful.
  • The friend whom I invited could not come.

In everyday conversation, people often use who instead of whom, especially when the preposition is not placed before the pronoun.

7. Common Mistakes

IncorrectCorrectReason
The man which helped me is kind.The man who helped me is kind.Use who for people.
This is the place which I was born.This is the place where I was born.Where refers to a place.
My car, that is red, is new.My car, which is red, is new.Do not use that in a non-defining clause.
The boy who's bag is blue is here.The boy whose bag is blue is here.Whose shows possession; who's means who is/who has.
The book who I bought is good.The book that/which I bought is good.Use which or that for things.
