• Hey guys, I'm Alex. Thanks for clicking and welcome to this lesson on

• adjective clauses and quantifiers, okay? Now if you want to know what an

• adjective clause is you can check out any number of the lessons on

• engvid.com that we have done in the past on this subject.

• Today we are focusing on adjective clauses with quantifiers. Now

• quantifiers are words that show a number, essentially. So here we have a

• bunch of sentences a quantifier like "both", "one", "all". Okay, it can be

• a number, "one", "two", "three", "four". It can be "a lot". It can be a

• percentage, even.

• So here we have, well we actually have six sentences, but let's say three

• sets of sentences. And I want you to tell me how can you combine these two

• sentences into one, okay? So we have the first sentence. It says, "Chris

• has two sisters. Both of them smoke." Now if you know anything about

• adjective clauses, you know that there are two types.

• There can be identifying, non-identifying -- non-identifying means it's extra

• quantifiers: they are always going to be non-identifying, which means it's

• always extra information. So this information about Chris's sisters -- "both

• of them smoke" is non-essential information, okay?

• Let's put this together though, so we can say, "Chris has two sisters",

• and as you know with adjective clauses -- non-identifying -- you put a comma ", both

• of"... now we have "them". Hmm, what do you know about adjective clauses?

• You always use relative pronouns, right? So what are some relative

• pronouns in adjective clauses? We have "who", "whom", "that", "which",

• "whose", "where", "when".

• In this situation, which one of those do you think we use? Okay, if you

• said, "whom" you are absolutely correct.

• Okay but you're saying, "Wait!

• Alex, I learned that in adjective clauses we only use "whom" when the

• subject is receiving an action."

• In this situation, the sisters smoke. They're doing the action, it

• should be "both of who smoke". Actually, in this situation, "whom". It

• doesn't matter if it's subject, object, who's doing the action,

• receiving the action -- you're always going to be using "whom" in the

• quantifier.

• Here we have "Nicki has two phones.

• One of them is broken." So we can say,

• "Nicki has two phones,

• one of"... okay, we have "them", so what do you think?

• "Which", "whom", "who", "that", "where", "when", "whose"? Okay as we know,

• a phone is an object.

• With objects you use "which". Now you're saying, "We can use 'which' or

• 'that'." However, in adjective clauses with quantifiers, such as this, we

• can't say, one of that is broken. We can only use "which" for objects.

• Okay? So: "whom" for people, "which" for objects.

• And finally we have "Tom's a writer. All of his books are popular." So

• we're talking about Tom, but we're also talking about his books in the

• second part of the sentence. So because we're talking about his books this

• is a possessive, so with possessives we know that we use "whose".

• "Tom's a writer, all of whose books are popular."

• Okay, so what I have just shown you are the three relative pronouns that we

• use with quantifiers and adjective clauses. And the only three you need to

• know for this structure are "whom", "which", and "whose".

• So, again, you can see the construction here, you have a quantifier: "both",

• "one", "all". You always have "of", so "both of", "one of", "all of". And

• then you have the relative pronoun, "both of whom", "one of which", "all of

• whose". And again: "whom" for people, "which" for objects, "whose" for possessives.

• then you guys can do the quiz.

• Okay, so in the previous examples, you saw

• the adjective clause with its quantifier in the second part of the

• sentence. That is not the only possible position.As you can see in these

• two sentences, it is also possible to put the adjective clause with the

• quantifier, in the middle of the sentence.

• So here we have, "J.K. Rowling, all of whose books are popular, is a great

• writer." So we're saying J.K. Rowling is a great writer, and here you have

• the quantifier. You're giving extra information about her. You're saying

• all of her books are popular -- "all of whose books are popular, is a great writer."

• In the second example, "The movie, most of which was boring, made me fall

• asleep." So you're saying the movie made me fall asleep, and in the middle

• part you're giving extra information, just like a regular adjective clause

• and you're saying that, "most of which was boring". "Most of" what? The

• movie, most of the movie was boring.

• Okay guys, so just so you understand you can put the adjective clause with

• the quantifier at the end of the sentence, in the second part. You can

• also put it in the middle, after the subject that you're trying to

• describe. In this case, J.K. Rowling, the author of Harry Potter, and here

• you have the movie, whatever the movie was, all right?

• Okay guys, if you want to test your knowledge of this, you can check out

• the quiz on www.engvid.com. Good luck!
