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 sir,

I would like to know whether the following sentence is grammatically correct. Is its syntax correct?

Sentence:

I politely request that you have my election duty cancelled.

 

Please clear my doubt.

Hello amitagnihotri585,

Yes, that is correct -- well done! It would also be correct to say 'I politely request that my election duty be cancelled'.

Best wishes,
Kirk

There is a problem with these exercises.  It isn't possible to do all 16 questions. 

Hello Sowerbicci,

The exercises seem to be working fine to me. There are 8 questions in Task 1 and 8 questions in Task 2, making 16 in all, and all are accessible. If you are having trouble, please explain what happens and we'll try to help.

Hai,

I am bit confused about the tense that we should use in the relative clause. When i am talking about past ,which one in the below is correct?

Finding a pair of shoes that go well with the frock was hard.

Or

Finding a pair of shoes that went well with the frock was hard.

Hello FathimaFrk,

Both 'go' and 'went' can be correct here. 

When you say this, if you are thinking more of all the time you spent that day looking for the shoes, i.e. more about the past, then 'went' is the more appropriate choice. The past tense form draws attention to the past action.

But if you are thinking more about the frock and how unusual it is in general, then 'go' is more appropriate. The present tense draws more attention to the frock.

We often use the present tense when talking about general truths, for example, the sun rises in the morning, ice is cold, etc. In this case, we'd be saying that it's difficult to find accessories to match the frock.

Does that make sense?

Best wishes,
Kirk

Hi there 🙋🏻‍♂️

I have a question that has been occupying my mind for some time now. Is the sentence below grammatically correct? 
“ The research was carried out so as to encourage more research on a topic which the researchers feel needs to be studied in more depth.” 
I didin’t get the part which goes like …which the researchers feel needs to be studied. How can we use feel and needs one after another. I would be so glad if you could reply with an answer. Thanks in advance 🙏

Hello ahmethoca,

The sentence is correct. The phrase 'the researchers feel' adds an extra layer to the sentence. If we remove it then we get this:

...a topic which needs to be studied in more depth.

Once you see this I think it's easy to understand the addition of 'the researchers feel'. You could add similar phrases such as 'I believe', 'people have always thought', 'it turned out', 'no-one doubts' and so on.

Hello everyone,

I have a question about defining relative clauses. In the student's book my daughter study, there are two sentences:
1. The book which/ that I read was very interesting.

2. The play (that/ which) we saw was great.

The explanation for the first sentence is: Defining relative clauses give information that is essential to the meaning of the main clause so we cannot omit them.
For the second sentence it is said that we can only omit the relative pronoun when it refers to the object of the main verb.
I am not an expert that's why I see no difference in the two sentences - I can omit that/ which in both without changing the meaning of each sentence.

Please, advice :)

Thank you in advance,

Ani

Hi Just_An,

You are right, "that/which" can be omitted in both of these sentences.

I can't be sure without seeing the book, but it seems the first sentence is not talking about omitting the relative pronoun only, but about omitting the whole relative clause "which/that I read". It is emphasising that the whole clause "which/that I read" is inseparable from "The book".
