We use a noun with ’s with a singular noun to show possession:

We are having a party at John’s house.
Michael drove his friend’s car.

We use s’ with a plural noun ending in -s:

This is my parents’ house.
Those are ladies’ shoes.

But we use ’s with other plural nouns:

These are men’s shoes.
Children’s clothes are very expensive.

We can use a possessive instead of a noun phrase to avoid repeating words:

 

Is that John’s car?   No, it’s Mary’s [car]. > No, it’s Mary’s.
Whose coat is this?   It’s my wife’s [coat]. > It’s my wife’s.

Hi,

If I have three or more nouns (e.g. persons) sharing possession of an item or items, would it be right to say that the apostrophe is only added to the last noun, as in the following:
"Dick, Mary, Charlene and Tim's car" ?

Also, under the same scenario where again all parties share possession of the same item or items, and should my phrase involve a personal pronoun, would it be right to say that the apostrophe is added only to the last noun before the personal pronoun, as in:
"Charmaine, Henry, Nic's and my last day at work"?

Appreciate your advice on the above, please.

Thanks!

Regards,
Tim

Hello Tim,

Both of your suppositions here are correct. Well done.

Hello Teachers,
Can I use "of which' as possessive form for inanimate object. For example, can I combine these 2 sentences
"I put the book on the table. The legs of the the table are almost broken" into
" I put the book on the table, the legs of which are almost broken"?
Thank you

Hello again Kaisoo93,

It is unusual to use 'of which' in this way. I'd recommend rephrasing the sentence with an adjectival prepositional phrase, e.g. 'I put the book on the table with the legs that are almost broken' or '... with the damaged legs'.

All the best,

Hello Kirk,
Thanks for your answer.

Hello. I have a question related to the usage of the possessive 's.
I read this example:
'The moon is Earth's satellite.'
But I know that we can't use the possessive 's with inanimate objects. So, why do we use the possessive 's in this case? Which ones are the exceptions to the rule?

Hello Daniel H,

I'm not sure where you heard that 's cannot be used with inanimate objects. It is perfectly fine to do so:

This is my house's bathroom.

I went through the university's main entrance.

The knife's edge was blunt.

 

Best wishes,

Hello Adya's,

I'm afraid that's not correct. The dictionary entry there says 

We don’t usually use the possessive ’s with things

and this is correct. However, this is not because of a grammar rule related to things as opposed to people. It is simply a statement of common use. We tend to use adjective forms or compound nouns rather than possessive 's when the item is one frequently described. For less common items the possessive 's is perfectly normal. Thus we would not normally use the possessive 's with the following common phrases

the car door

the car engine

the car boot

the kitchen cupboard

the table edge

the fridge handle

However, we would use the possessive 's for other less fixed phrases such as

the car's colour

the car's problem

the car's sound

the kitchen's shape

the table's position

the fridge's plug

 

I hope that clarifies it for you. It is not a grammar issue but a question of convention.

Oh, I see. Well I read it just here; Mr. Kirk was replying to somebody about the usage of possessive 's:
https://learnenglish.britishcouncil.org/es/comment/104482#comment-104482.
He was explaining that it is correct to say 'Frogs' legs' but not 'Car's door'.
I quote:
"That's very observant of you! The difference between 'the car's door' and 'frogs' legs' is that a car is an inanimate object and frogs are animals. In other words, 's is most often used with people, animals or groups of living beings, and not with inanimate objects."
But he has also said that it is not a hard and fast rule, so I guess that is the reason why in some cases we can use the possessive 's with inanimate objects and why in some others not. I do really apreciate your help, your response clarifies it more for me.
