We use the possessive of a noun in phrases like the boy's name and Vicky's room. We form the possessive like this.
Singular noun: 's boy -> boy's Vicky -> Vicky's
Plural noun ending in s: ' boys —> boys' tourists ~> tourists'
Plural noun not ending in s: 's men —> men's children —> children's
We can use the possessive form with another noun or on its own.
I've met Rachel's family, but I haven't met Vicky's. (Vicky's - Vicky's family)
B The boy's name or the name of the boy?
Compare these structures.
THE POSSESSIVE FORM PHRASE WITH OF
the boy's name the name of the boy
the boys' names the names of the boys
the men's names the names of the men
Sometimes we can use either the possessive (the boy's name) or a phrase with of (the name of the boy), but often only one is possible. We normally use the possessive with people and animals.
my friend's house Claire's idea Daniel's brother our neighbour's garden the dog's owner
the policemen's uniforms the women's changing room the Parkers' car
We normally use of with things, and not the possessive form. the side of the house NOT the house's side the result of the match not the match's result the day of the meeting not the meeting's day
But we use of with people when there is a long phrase. the house of one of our teachers at college the address of those people we met in Spain
not those people who we met in Spain's address
We can use both structures for places and organizations. London's museums or the museums of London the earth's atmosphere or the atmosphere of the earth the company's future or the future of the company the government's intentions OR the intentions of the government
