Read the explanation to learn more.

Grammar explanation

Relative clauses give us information about the person or thing mentioned. 

Defining relative clauses give us essential information – information that tells us who or what we are talking about.

The woman who lives next door works in a bank. 
These are the flights that have been cancelled.

We usually use a relative pronoun or adverb to start a defining relative clause: who, which, that, when, where or whose.

who/that

We can use who or that to talk about people. that is more common and a bit more informal.

She's the woman who cuts my hair.
He's the man that I met at the conference.

which/that 

We can use which or that to talk about things. that is more common and a bit more informal.

There was a one-year guarantee which came with the TV.
The laptop that I bought last week has started making a strange noise!

Other pronouns

when can refer to a time.

Summer is the season when I'm happiest.

where can refer to a place.

That's the stadium where Real Madrid play.

whose refers to the person that something belongs to.

He's a musician whose albums have sold millions. 

Omitting the relative pronoun

Sometimes we can leave out the relative pronoun. For example, we can usually leave out who, which or that if it is followed by a subject.

The assistant [that] we met was really kind.
   (we = subject, can omit that)

We can't usually leave it out if it is followed by a verb.

The assistant that helped us was really kind.
   (helped = verb, can't omit that)

Hello aymanme2,

Both 'that' and 'who' are possible in this sentence. I wouldn't say either is better; both are fine. As you say, we can use 'who' for things which we see as comprised of people: companies, organisations, teams, nations etc.

Hello The LearnEnglish Team, I would be greatful if you could help me with the sentence below; Germans are good at dealing with time-management, wich is often spoken and adviced to have by motivators and most successful people, which i really want to get I think that in this sentence both non-defining (which is often spoken and.....) and defining (which i really want to get) relative clauses are used. Actually, Is it possible to use both clauses( defining and non-defining) in a single sentence?

Hello BobMux,

To be honest, I'm not completely sure if it's possible to use both sorts of relative clauses in the same sentence. What I can say with confidence is that I wouldn't recommend it.

All the best,

Hello, can you explain me why in the sentence: They ate at a restaurant ___ serves only vegan dishes. We can't put Where? Because we are talking about a place

Hello sisi,

You need to use a pronoun in the gap as it is the subject of the verb 'serves'. 'Which' is a pronoun, but 'where' is actually an adverb. If you use 'where' then you need to add a subject after it:

They ate at a restaurant which serves only vegan dishes.

They ate at a restaurant where they serve only vegan dishes.

Good morning LearnEnglish team, Is there any fixed rule concerning the position of participle adjectives, i.e. whether they are placed before or after a noun? Take the term "1kg of fish caught", for example - is the postponed position of the adjective "caught" (as a reduced relative) binding, acc. to English grammar rules, or is it just formal style and the term "1kg of caught fish" would also be fine? The only source I found is "Advanced Grammar in Use" from Cambridge University Press, Unit 69 (B) regarding "participle adjectives and compound adjective, e.s". The author gives examples of such adjectives - some of them are typically found directly before the noun, others are usually go directly behind the noun, and the third group of adjectives may be placed before or after the noun. Many thanks in advance for your assistance.
