    I have a question about the word whom, and how to use it in a sentence. Could you give us a more detailed definition? It is a word I often confuse with the word who.

    Friday, July 27th 2012

      most of the times students confuse between Who and Whom.Who as Mr Alex explains refers to a person doing the action Ex: The man who is overthere is my father.However, when we use Whom we refer to a person recieving the action and notice that “Whom” is followed by a Subject unlike “Who” which is followed by a Verb. Ex: The man whom I gave the papers is my teacher at school. I hope you’ll get it.

      Tuesday, November 27th 2012

        In my understanding who person doing action and whom person receiving action.

        Thanks Alex. I really like your teaching skill.

Thank you

Wednesday, March 23rd 2011

nice video.

Thursday, March 24th 2011

hi alex… thank you so much but i wanna ask u quistion
what is the deference between WHO AND WHOM ??
pls give me the answer

Friday, March 25th 2011

    Hi halimblack,

    Use “who” when someone does an action, and “whom” when someone receives the action. For example:

    “The man who won the lottery was on TV yesterday.”

    “The man whom I saw was wearing a blue jacket.”

    In speaking, most people omit the differences and just say “who,” but if you are writing, you should be aware of the differences.

    Sunday, April 3rd 2011

      Can I write, for example : My father, who was travelling, called me yesterday?
      I’m not identifying (you usually have 1 father :p) but just giving extra information.
      Is it correct?
      Thanks xx

      Thursday, March 10th 2016

Thank you. I loved it.

Sunday, March 27th 2011

hi alex! your lesson is very helpful but i wonder why we can’t say “The car, which I bought, is a Toyota.” but we have to say
“The car that I bought is a Toyota.” ? i wait your answer, thank you.

Wednesday, March 30th 2011

    Hi mellibarara,

    You can actually say both sentences, but the meaning will be different. If you say “The car that I bought is a Toyoto,” you might be talking to your friends, who had no idea that you were buying a new car. If you say, “The car, which I bought, is a Toyota,” you are just giving extra information about a car that your friends might know you had the intention of buying. You might add the “which I bought” part because you are proud of yourself for being able to afford it.

    Sunday, April 3rd 2011

      Wow!!! Thank you very much, Alex.

      Wednesday, April 6th 2011

      Can I write, for example : My father, who was travelling, called me yesterday?
      I’m not identifying (you usually have 1 father :p) but just giving extra information.
      Is it correct?
      Thanks xx

      Thursday, March 10th 2016

Monday, May 16th 2011

Monday, May 16th 2011

Thanks Alex for this lesson. I must admit, that before watching this video, I’d completely forgotten everything about identifying and non identifying clauses… Surely once I’ve learnt that at school… (oh I hope so… maybe… or not…I don’t know! I’m not so sure anymore!!!)In any case, thank you!

Monday, May 16th 2011

hi. i can not understand when i consider that clause is identify clause or non-identify clause. when i consider is extra clause or essential clause i can not omit it

Saturday, May 21st 2011

Saturday, May 21st 2011

Hi teacher, i hope you are fine.The score 6/10 is not good i don’t understand between using the sentences My sister who is from Paris is visiting me this weekend.” How many sisters do I have? and My sister, who is from Paris, is visiting me this weekend.” How many sisters do I have? Please me to explain again.

Thursday, May 26th 2011

    may be i can help you to answer that,
    the different betwent the sentence is a (komma) but in the sentence 1 you have many sisters because no komma in there, but in sentence 2 you have only one sister because the sentence the explain with a comma. hope its help..

    Sunday, January 1st 2012

Thanks so much for lesson .
Sorry can i ask to confirm how i understand ?
We use “which” when the clause ‘s not indentify, need more information to make clear ?

Saturday, May 28th 2011

Thanks so much for the lesson. I love English ( I am a student of English Studies;)) and grammar as well as writing was always my favourite part, but these relative clauses were quite problematic for me. Not any more, thanks a lot ;)

Sunday, May 29th 2011

Wednesday, June 8th 2011

Wednesday, June 8th 2011

In the sentence
The teacher whom I spoke to didn´t like me.
which is the suject? If the teacher is subject then it is receiving the action not doing the action like the first one we have about the girl.We are getting more information abt teacher not who spoke. I m confused.
What does possesive mean?

Tuesday, June 14th 2011

I hope you do not mind give more information about identifying clause and non identifying clause.

Saturday, March 31st 2012


Tuesday, May 8th 2012

Hii Alex,
A lot of thanks to you for revising us this part of grammar that we were taught in school.We also learnt another aspect of grammar relating to reduced relative clause.Based on that,I have shortened some sentences retaining their meaning unchanged.
1.The car that I bought is a Toyoto.
It can simply be said that I bought a Toyoto car.Apart from that, the sentence could be converted into a reduced relative clause as follows:
The car bought by me is a Toyoto.
Furthermore, if we consider the sentence which reads as:He is a person who always arrives on time.
If it is turned to a reduced sentence, it would be “He is a person always arriving on time”.
I have one more question to you related to transformation of a noun to its corresponding adjective form.I have written some sentences which contain an adjective in them.
1.I had paid the metered fare to the cabbie before leaving it.
2.The uniformed waiters served us in the pub which we visited yesterday.
Here,one thing to notice is that the words such as uniformed, metered have “ed” endings whereas their noun forms are uniform and meter respectively.I want to know that it is a rule to add “ed” at the end to turn it to an adjective.I request you to solve this problem of mine.

Saturday, May 12th 2012

Hello Alex!
I have a question about “identifying clause” and “non-identifying clause.”

Thank you so much..

an excellenct lesson

Friday, March 8th 2013

Dear Alex! Thank you for your useful lessons! I want to ask a question. Yesterday I had a test on relative clauses. One of the tasks was to put commas where neccessary. Do we need to put a comma in sentence “Marsha is a girl who enrolled to our college this year”? My teacher says we need (Marsha is a girl, who enrolled to our college this year) but I can*t understand why. Please explain me!

Wednesday, March 13th 2013

    Hi Javanna.
    I’m not a teacher, but I agree with you. I think we don’t need a comma, because “…who enrolled our collegge…” is an identifying clause. If not, I wish Alex could explain us.

    Sunday, March 31st 2013

      Sorry for writing collegge instead of college…

      Sunday, March 31st 2013

    My suggestion would be, if one doesn’t know the person’s gender than use a comma.

    Some other examples:

    Jack said the teacher is a lazy fellow. Versus: Jack, said the teacher, is a lazy fellow.

    The queen who was sitting in the first car was killed. (, but the ex-queen sitting aside was slightly hurt.)
    The queen, who was sitting in the first car, was killed. (= so called Non-defining or Non- identifying relative clause.)

Friday, March 29th 2013

hi dear alex ,im wondering what is the difference between that and witch in non

Sunday, March 31st 2013

please answer to my question because I am about to understand everything in this topic.
my question is.
the verb in the relative clause how can i decide which tense i have to use, is it according to the verb in the beginning of the sentence .
in your examples you said
1- I bought a car which is red.
2- I saw a car which was red.

Monday, April 1st 2013

Great lesson. Thanks Alex

Friday, May 17th 2013

Hi! Thank you very much Mr Alex!
I have 2 questions, one of them about your video and next one about the quiz.
1. Why most of your videos are not able to download or save them? we should just see it one time. because in our country due to the low speed of Internet, I myself can’t see it more, but by saving it I can have a review when it is necessary.
2. Why at the end of the quiz there is no option to choose and do the quiz again?
thanks in advance.

Saturday, July 6th 2013

Thanks this information is useful

Monday, July 22nd 2013

Impressive lesson Alex! You have teached an important english topic. I think I learned a lot from your lecture. Thanks for the advance!

    Sunday, December 6th 2015

Good afternoon Alex, how are you?
Firstly, thank you for this video, it was really helpful to understanding about relative clauses.
I’ve done the Quiz and I had two mistakes. Could you help me with them?

The first one:

4. Which sentence is correct?
The man whom I spoke to said I was on the wrong train.
The man who I spoke to said I was on the wrong train.

In this exercise I’ve chosen the second one, but the correct answer is the first one. Why?

And my second mistake was in the 6th question, which is:

6. Which sentence is correct?
He’s a person whose always arrives on time.
He’s a person who always arrives on time.
He’s a person whom always arrives on time.

In this question I answered the third one, but the right answer is the second.

Thank you so much and I’m looking forward to your answer.

King regards,
Matheus Majer

Wednesday, November 18th 2015

    First one:
    It is whom, because the man receivces the action, I spoke, and the man received that so the man is whom. It would have been who when the man spoke to me. (“The man who spoke to me yesterday, had sent me a lettre.” for example)
    Second one:
    He is the subject, he is a person. The relative clause refers to the ‘he’. Because he’s a person you can use: who, whom or whose. Their is no possession so it can’t be whose. “He” is not the one receiving the action, “He” is the person doing the action: arriving on time. So because the subject is the person doing the action (arrive on time),the correct answer should be who.
    I hope my answer helps you.

Monday, November 23rd 2015

I still not understand,whan we know to use defining or non defining relative clause in that quiz

Sunday, December 6th 2015

Thankyou! I’ve got one question:
In the beginning of the video, there are two sentences, in the first sentence “My sister who is from Chicago” is the subject, is “My sister” the subject in the second sentence?

Sunday, February 14th 2016

I got 100 yay!

Monday, February 29th 2016

Can I write, for example : My father, who was travelling, called me yesterday?
I’m not identifying (you usually have 1 father :p) but just giving extra information.
Is it correct?
Thanks xx

Thursday, April 25th 2019

Thanks, Alex. I really liked your video because the way you taught us about identifying and non-identifying clauses were super easy. I was really struggling with those problems. Hope to see your more videos on research-related writing kills and provide us suggestions.

Sunday, July 21st 2019

Thanks for a lesson.
That topic has always been confusing for me.
Especially when we can use which or that.
Best wishes for you. ;)

Hello. There is a rule that says “Don’t use subject pronouns after relative pronouns”. Eg: Feijoada is a dish that it is famous in Brazil. The correct sentence is without “it”. My question is because you wrote differents examples with a subject after relative pronouns. Please can you answer this doubt?

Hi Alex,
my score was 7 out of 10; I understood the mistakes made on Q4 and Q9 but I don’t understand why Q7 is wrong;
That’s the street, which I grew up on.
Is it because the sentence ended thus no more info has been added?
Thanks for your answer!
