That's what Rodolfo from Brazil wants to know.

And that's what we're talking about on this.

Learners questions Now I could barely hear anything now.

This is a bit of a tricky question, but who, whom and whose are generally used in two main areas?

Questions on dhe relative clauses Okay, regarding questions.

And as many of you know who whom and who's our question words?

Or if you want to be technical, interrogative pronouns Yeah, that's right.

Yeah, I'm so cool.

We use the question.

Would who when asking about a person and it goes at the beginning.

Off the question.

For example, welcome to BBC learning English.

Who do you know whom is also usedto ask about people?

But it is the object form off who?

It's quite formal and not really used in speech very much.

But you do see it informal writing.

For example, when you're writing a letter to a company and you don't know who to send it to.

Specifically, you can put help to whom it may concern, whom is often accompanied by a proposition and where it is.

We should put the proposition in front of the home.

For example.

Toe, Whom did you speak yesterday?

Who's is also a question word, and it's used to ask about possessions.

It acts like a determiner such as my, his or her on.

Because of that, it must be followed by a noun, for example.

Oh, uh, whose phone is this?

Anyone?

Anyone?

No.

Okay, okay, let's stop for a second so I can tell you all about the learner's questions.

Playlists?

And don't forget to watch until the end of the video, where you'll find a full summary slide.

Now for relative clauses.

There are two types of relative clause defining, which specifies which now we're talking about and non defining, which adds extra information to a particular now.

Now I don't have time to explain the rules in full because they're very complicated.

But go to our website BBC learning english dot com, and you'll find tons of materials to help you with this extremely useful grandma.

So who and whom are relative pronouns that represent a person within a relative clause, whether it is the subject or the object who can always be used?

For example, the person who lives upstairs is very noisy.

That's a subject.

But John's the guy who you met yesterday that an object just like in the question whom is the object form of who, in a relative clause, it represents a person that is the object of that relative clause.

Again, it's mostly formal and mostly used in a written style.

For example, the person whom I spoke to denied making any noise again.

The position of the proposition is important for the most formal version.

Put the proposition before the whom, for example, the person to whom I spoke denied making any noise.

Okay, just like in the question, whose is used to talk about a possession on like the determine is my his her, its et cetera.

It must be followed by a noun, so don't forget, it can be used to talk about the possessions of a person.

Example.

I know a baker who's cakes are not delicious.

It could be used to talk about the possessions of an animal.

It's the story of a dog whose best friend is a cat.

What, and it could be used to talk about the possessions of an object.

For example, that's the tree whose branches looked like a ghost.
