It is used with nouns referring to people, groups of people, countries, and animals. 'Belonging to' or 'ownership' is one of the relationships it expresses :
John owns a car. ('John' is the possessor or owner)
It is John's car.
America has some gold reserves. ('America' is the owner)
They are America's gold reserves.
Form
To form the possessive, add 's ('apostrophe -s') to the noun.
If the noun is plural, or already ends in -s, just add: ' (an apostrophe).
For names ending in -s:
In speaking- we add the sound /iz/ to the name, but -in writing- the 's form is common. e.g. Thomas's book, James's shop.
Examples:
The car of John = John's car.
The room of the girls = The girls' room.
Clothes for men = Men's jobs.
The sister of Charles = Charles's sister.
The boat of the sailors = The sailors' boat.
The possessive is also used to refer to shops, restaurants, churches and colleges, using the name or job title of the owner. Examples:
| the grocer's | the doctor's | the vet's |
| the newsagent's | the chemist's | Smith's |
| the dentist's | Tommy Tucker's | Saint Mary's |
I've got an appointment at the dentist's at eleven o'clock.
