Possessive ’s in the Singular
To express that something belongs to a person, animal or country, we use the possessive ’s.
- Example:
- This is Jim’s budgie.
- The budgie’s name is Nibbles.
- Jim is going on holiday to England’s south coast.
In English, we also add the possessive ’s if the noun already ends with s.
- Example:
- Nibbles’s feathers are green.
The possessive ’s is also used in time expressions.
- Example:
- in a week’s time
Possessive ’s in the Plural
In the plural, we only use the possessive ’s with irregular plural forms.
- Example:
- He can whistle children’s songs.
If it’s a regular plural form that just ends with s, we simply add an apostrophe.
- Example:
- Jim keeps Nibbles in his room so that his parents’ cat cannot reach him.
Possessive case with “of”
We use the possessive form with of mostly for inanimate objects.
- Example:
- When you open the door of his cage, …
To Note
If we’re referring to an inanimate thing that has a clear connection to people, then we can also use the possessive ’s.
- Example:
- Australia’s economy
- the ecomony of Australia
