Apostrophes and Possessive Form – Definition
The possessive form is a way to show belonging or ownership in writing and speaking. The possessive form can help us understand when something belongs to someone or something else. It also shows the connection to a place or a relationship with someone or something.
We show possession by adding an apostrophe and the letter s to the noun that something belongs to: girl’s dress.
Apostrophes and Possessive Form – Strategy
When we want to use an apostrophe for possessive nouns, we need to follow several simple steps:
- First, we identify who or what something belongs to (a noun).
- Then, we identify the thing or the relationship that the noun has.
- Lastly, we add an apostrophe and the letter s to the end of the word.
For example: if we want to say that the book belongs to Tom, we need to know who something belongs to (Tom). Then, we identify the thing that belongs to him (book). Finally, we can add an apostrophe and the letter s to the end of the noun (Tom’s). What is the possessive form of the book belonging to Tom? Tom’s book
Apostrophes and Possessive Form – Rules
There are several rules for using an apostrophe in possessive nouns. In the example above, we looked at a singular noun. Now, let’s take a look at the use of an apostrophe in plural possessive nouns.
Plural nouns are usually followed by the letter s, for example: friends, parents, cats, toys. When we make possessive plural nouns, we add an apostrophe after the last letter, and do not add another s. For example: friends’ house, cats’ toys, parents’ car.
Even though most plural nouns are formed by adding the letter s at the end of the word, some plural nouns don’t follow this rule. They are called irregular plural nouns. Some examples of irregular plural nouns are: children, people, men, women, mice, sheep, fish. To make an irregular plural noun possessive, we add an apostrophe and the letter s to the end of the word: children’s cookies, people’s choice, mice’s food.
Apostrophes and Possessive Form – Summary
To show belonging or ownership in writing and speaking, we use a possessive form. In singular and irregular plural nouns, we make a possessive form by adding an apostrophe and the letter s to the noun that something belongs to. In regular plural nouns, we add an apostrophe after the last letter, and do not add another s. See examples below:
