Give extra details about people and things: relative clauses.

Relative clauses add extra information about a noun without starting a new sentence — they let you combine two ideas smoothly. The relative pronoun you choose depends on what you're describing: a person, a thing, a place, a time, or possession.

Why this matters This lesson connects directly to your progress: it covers who and that, for people; which and that, for things; whose, where, when, and why. Mastering this content lets you move forward confidently, and reinforces patterns you'll use again later. Take time to review every example before moving to the assessment — repetition is what actually locks knowledge in long-term.

What will you be able to do?

The goals of this lesson.

02

Before you start

You already build sentences with a subject and a verb. This lesson teaches you to combine two ideas into one sentence using "who", "which", and "that" — relative clauses.

03

Who and that, for people

"Who" refers specifically to people. "That" can also refer to people in everyday speech, though "who" is considered more precise.

PronounRefers toExample
whopeoplethe woman who called
thatpeople (informal) or thingsthe man that called

Examples

The woman who lives next door is a doctor.
Who (people)
I have a friend who speaks four languages.
Who (people)
The man that called earlier didn't leave a message.
That (people)
Students who study hard usually get good grades.
Who (people)
The teacher who taught me math retired last year.
Who (people)

Who (people)
The person that stole my bike was never caught.
That (people)

Who (people)

04

Which and that, for things

"Which" and "that" both refer to things or animals — "that" is generally more common in everyday spoken English.

Examples

The book which I bought yesterday is amazing.
Which (things)
This is the restaurant that we visited last week.
That (things)
The car which broke down is finally fixed.
Which (things)
I lost the keys that were on the table.
That (things)
The movie which won the award was excellent.
Which (things)
This is the house that my grandfather built.
That (things)

05

Whose, where, when, and why

"Whose" shows possession, "where" refers to a place, "when" refers to a time, and "why" refers to a reason.

PronounRefers to
whosepossession
wherea place
whena time
whya reason

Examples

That's the man whose car was stolen.
Whose (possession)
She's the teacher whose class I loved the most.

Reading

Read the text and answer the questions. You can try as many times as you want.

My neighborhood has changed a lot. The old bakery, which used to sell the best bread in town, closed last year. The family who owned it moved to another city. Now there's a coffee shop where the bakery used to be.

I still remember the baker, whose name was Mr. Ramirez, who always gave free cookies to kids. The street where I grew up looks completely different now. Sometimes I miss the days when everything felt simpler.

1. What used to be in the neighborhood?

2. What happened to the family who owned it?

3. What is there now instead?

4. What was the baker's name?

5. What did the baker give to kids?
