Possessives

Showing possession in English is done by adding an apostrophe and an s to singular nouns to transform them into their possessive form:

The car's front seat
Bartkowski's book
A hard day's work


Most plural nouns already end in s. To create their possessive, simply add an apostrophe after the s without the extra following s:

The Pepins' house is the big blue one on the corner.
The lions' usual source of water has dried up.
The witches' brooms were hidden in the corner.


With nouns whose plurals are irregular, you will need to add an apostrophe followed by an s to create the possessive form.

She plans on opening a women's clothing boutique.
Children's programming is not a high priority.
The geese's food supply was endangered.
