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)

Which one(s) is/ are correct? Thank you so much!
Sorry about the typos!
Hello Giao Huynh,
I'm afraid we don't generally provide help with answers to questions from other sources. We're happy to explain the rules and tendencies of English but if we start just providing answers to these kinds of questions we'll end up doing users' homework and tests for them, and that's not our role!

Hello Peter. Thank you so much for your effort to reply to my question. I understand what is implied in your answer. To clarify, I am an English teacher, and the question is included in one of our tests for our/my students. The thing is, there has been debate among us teachers over the answers to the questions. And my side is that:
1. The children who/that are playing soccer over there are my students: CORRECT.
2. The children are my students, who are playing soccer over there: INCORRECT: non-defining relative clause is used to add information to a Noun in a complete clause in terms of grammar and meaning, which this one does not satisfy. Plus, instead of saying this, we had better say: “My students are playing soccer over there.” The students are obviously children.
3. The children that/ who are my students are playing soccer over there: INCORRECT: Anyone’s students can be students, not just my students. Therefore, this defining relative clause in the sentence has no use of defining the noun “the children”. Plus, if there are two clauses in a sentence, one generally (they are my students) and one specifically (they are playing soccer over there) indicates some noun, we’d better use the more specific one (they are playing soccer over there) as the Relative Clause.
From my side, I have just presented what I understand about the use of Relative clause in general, and in this case particularly. The other side, however, concluded that all were correct. Honestly, I came up with seeking for help from your group, a prestigious one, in order to find out the right thing to teach our students. So can you still please help?
Thank you,
Giao
Hello again Giao,
Thank you for the explanation. From time to time students try to use LearnEnglish to get answers for their homework so we are quite careful about this - as a teacher yourself I'm sure you understand.
With regards to the sentences:
1. I agree that the first sentence is correct. This is fairly standard defining/restrictive relative clause identifying which children we are talking about.
2. Again, I agree here. However, this sentence is difficult. In terms of grammatical construction it is fine but it is very awkward conceptually. 'The children' already points out the people we are talking about, so it makes no sense to then point them out again with a non-defining relative clause. You could, however, think of a context in which you might say something like this. For example, imagine I show a photo of some children. I might say 'The children (i.e. the ones in the photo) are my students. Then I notice that they are playing soccer and I add this information. However, we would usually signal this explicitly in some way. For example:
The children are my students - who are playing soccer over there, in fact / actually / now that I look / by happy chance / right this moment.
Without this explicit signal that you have just noticed something new I don't think the sentence works.
3. The third sentence is correct. Imagine a context in which there are several groups of children. You want to identify the group which is formed of your students. To do this you use a defining relative clause:
The children who are my students are playing soccer over there. [as opposed to the children who are not my students, who are playing tennis]
I hope that helps to clarify it.

Hello LearningEnglish team,
In these examples:
> Summer is the season when I'm happiest.
> That's the stadium where Real Madrid play.
Can we omit the pronouns "when" and "where"? Or is it ungrammatical to do so?
> Summer is the season I'm happiest.
> That's the stadium Real Madrid play.
Many thanks,
Hieu Nguyen
Hi Hieu Nguyen,
We can omit "when", but not "where". However, omitting "where" is sometimes done in the phrase "the place (where)", e.g. "If we go back to the place (where) we started, we'll find the right way." or "I tried to find the place (where) I met her but I couldn't find it again."
I hope that helps.

Hello Mr. Jonathan R,
Thank you for your answer! However, for me, "the place" can replace "the stadium" in the example:
> That's the place/the stadium where Real Madrid play.
Then why can't we leave out "where" in that example? Is this some kinds of conventions in English?
Also, is it acceptable that we omit "when", "why" or "where" when possible in more formal contexts (like in writing)?
Hieu Nguyen
Hi Hieu Nguyen,
If you only look at the structure of the sentence, then yes - "the place" can replace "the stadium". But language use is not only a matter of structure/grammar. Words have individual characteristics too, including how they combine with other words in common phrases, and these cannot be described with grammatical rules. For whatever reason, it has become relatively common to omit "where" after "the place", but not after "stadium" or other words denoting places. It's a matter of vocabulary usage too, not only grammar.
Yes, it is acceptable to omit relative pronouns in formal writing. However, in more precise writing (e.g. technical reports or legal writing, or when you just want to express yourself clearly), it may be better not to omit them, to ensure maximum clarity of meaning. (Precise writing is not always formal writing.)
I hope that helps.

Hello again Mr. Jonathan R,
Thank you for your detailed explanation. I get it now.
Hope you have a good day, sir.
Dear Kirk, first of all, my class and I love your name and we think you’re very slayyyy! But your exercises aren’t done correctly, because it only shows a certain number of questions to different people. I got 10 questions out of 16, my friend got 8 questions out of 16 and my other classmate got 13 questions out of 16. Please fix your error.
Thank you for your attention, xoxo 💋
Hello chicavampiro,
I'm glad to hear it!
Regarding your question, in each exercise, you have to choose 16 options (this is what '16 items remaining' means), so the questions can have one, two, or three correct options.
For example, in Grammar test 1, for the first sentence, 'who' and 'that' are both correct; for the second sentence, 'who', 'that' and '–' are correct. You have to tick the boxes for all of these answers.
You can also see the correct answers: after you press the 'Finish' button, press the 'Show answers' button to see them.
Hope this helps you and your friends and classmates.
Best wishes,
Kirk

Hello BobMux,
It's not clear in this case whether the farmers use the substance or the tank. Usually the context will make it clear, but sometimes you have to ask for more information to know for sure.

Hi Quynh Nhu,
It depends on which structures can go with the verb. The verb here is remember, and remember can be followed by a question word (as in your sentence 1) or a noun phrase (as in your sentence 2). It can be followed other structures as well, e.g. a that clause and an -ing verb - see this Cambridge Dictionary page for examples.
Other verbs may have different structures. With meet, for example, it's possible to say I would like to meet the person who helped me but not
I would like to meet who helped me.I hope that helps!

Hello ayman hijazin,
I'm afraid we don't provide answers to questions and tasks from elsewhere. We're happy to provide explanations of how the language works and to explain our own materials, of course. If we answered questions like this we'd soon end up doing users' homework and tests for them, which isn't really our role!

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.
Peter
The LearnEnglish Team
Hello aymanme2,
Yes, you could also use whom here as the pronoun is the object of the verb phrase 'I work for'.
You can read more about who and whom on this page:

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 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.

Hello Gab07,
Non-defining relative clauses have commas before the relative clause, while defining relative clauses do not. Thus, the key is to indentify if your sentence is a defining relative clause or a non-defining relative clause:
> relative pronouns and relative clauses
> defining relative clauses
> non-defining relative clauses
In brief, if the relative clause identifies the noun and is necessary for the sentence to make sense, it is a defining relative clause. If the relative clause simply provides additional but not essential information, it is a non-defining relative clause.
For example:
"my brother is dating Mary, who I can’t handle"
the relative clause does not tell us anything essential to identifying Mary - it does not tell us 'this Mary and not the other Mary - so it is a non-defining relative clause and a comma is used.
"the people he works for no longer live in Belgium"
Here, the relative clause gives us essential information. It tells us which people you are talking about. Without the relative clause the sentence would make no sense as it would refer to all people or people in general.
I hope that helps. We don't provide answers for tasks from elsewhere, so I'm not going to give you the answers to all of the questions. The explanation should help you work out the others for your self, I hope. Good luck!

Hello Maryami123,
No, we do not omit whose, where and when from relative clauses.

Hi Yigitcan,
Actually, we can use where figuratively, to refer to something which can be imagined as a space containing other things. In this example, the romantic comedy film contains characters and story events. We often use where like this to refer to situations, processes and stories. There are more examples on this page in the Cambridge Dictionary.
Does that make sense?
Jonathan
The LearnEnglish Team
Hi Yigitcan,
Yes! Instead of where, you can use which, but it must be together with in:
That's because the clause (two heroes end up failing in love) is an action/event that happens in (i.e. inside) the romantic comedy. The clause doesn't describe the romantic comedy (as in, for example: It's a classic romantic comedy which has two heroes).
Best wishes,
Jonathan

Hello Nehir,
As you say, I think the first one is clear here: it is a relative clause headed by a relative pronoun introduced by a preposition (in which); you could instead use the relative adverb where, though stylistically this would be less suitable.
The second example is also a relative clause, but is reduced. The full (non-reduced) form would be as follows:
I think the other way this could be seen is as a participle clause. However, participle clauses have an adverbial function rather than adjectival, and in your sentence the function is clearly adjectival.
You can read more about participle clauses on this page:

Hello Zamra,
You can use both that and which in defining relative clauses.
In non-defining relative clauses that cannot be used.
As far as meaning goes, that can refer to people or things. Which can only refer to things. Other than that, the two are interchangeable. That is more common in spoken English.

Hello abo omar,
It's perfectly fine to use whose with things as well as people, so your sentence is correct.
