The relative pronouns are:

 

Subject Object Possessive
who who(m) whose
which which whose
that that  

 


We use who and whom for people, and which for things.
Or we can use that for people or things.

We use relative pronouns:

after a noun, to make it clear which person or thing we are talking about:

the house that Jack built
the woman who discovered radium
an eight-year-old boy who attempted to rob a sweet shop

to tell us more about a person or thing:

My mother, who was born overseas, has always been a great traveller.
Lord Thompson, who is 76, has just retired.
We had fish and chips, which is my favourite meal.

But we do not use that as a subject in this kind of relative clause.

We use whose as the possessive form of who:

This is George, whose brother went to school with me.

We sometimes use whom as the object of a verb or preposition:

This is George, whom you met at our house last year.
This is George’s brother, with whom I went to school.

But nowadays we normally use who:

This is George, who you met at our house last year.
This is George’s brother, who I went to school with.

When whom or which have a preposition the preposition can come at the beginning of the clause...

I had an uncle in Germany, from who[m] I inherited a bit of money.
We bought a chainsaw, with which we cut up all the wood.

or at the end of the clause:

I had an uncle in Germany who[m] I inherited a bit of money from.
We bought a chainsaw, which we cut all the wood up with.

We can use that at the beginning of the clause:

I had an uncle in Germany that I inherited a bit of money from.
We bought a chainsaw that we cut all the wood up with.

Hi, I´m Fernando from Mexico City

Hi, I'm Mosaddaq2 from Dhaka City.
This is the very helpful site to improve our English skill.

Hello everybody, I'm Phuong Anh. 
I want to improve my English, help me please. Thank you so much!
 

I am just wondering if we can use who after the only person.
Actually, what I learnt is that I cannot use who or which but that after the the only, the very, the same.
Can I really say "She is the only person who really understands me."?

Hello lord0221 -
 
Yes, you can use 'who' after 'the only person'! Your example is perfectly OK. You might be thinking about the difference between defining and non-defining clauses. Defining clauses give essential information, like in your sentence (the only person who – what? We need to know!). Non-defining clauses give additional information and use a comma before who, and you can't use ' the only person' and so on with a non-defining clause.
 
Hope that helps!

Hello.
 
Can I use a preposition at the end of the sentence which has the objective relative pronoun "whom" ?
 
As for an example;
Is it correct to say;
'I had an uncle in Germany, whom I inherited a bit of money from.' ?
 
I've placed the preposition "from" at the end of the sentence.  Is it correct?
 
This lessons says the following;
"When whom or which have a preposition the preposition can come at the beginning of the clause..."
I had an uncle in Germany, from who[m] I inherited a bit of money.
 
Thank you.
:)
 
 

I mistakenly wrote my previous message as the tutorial clearly explained what I had wanted to know but hurriedly overlooked the point.
 
It is possible to use the preposition "from" at the end or in the beginning of the following;
 
'I had an uncle in Germany, whom I inherited a bit of money from.'
 
OR
 
'I had an uncle in Germany, from whom I inherited a bit of money.'
 
Sorry for the inconvenience.
:(
 

A little confusion about THAT. Please give more clarification.

I'm looking for the grammar section that involves using comma correctly. Does anybody knows?
