Apostrophes

Definition

Apostrophes are important because they help to clarify meaning and make our writing more precise. They are normally used for two different reasons:

  1. To show a noun is in the possessive case.
  2. To show that letters have been omitted from a word.

Apostrophes can be tricky to use correctly, so it’s important to pay attention to their usage to avoid confusion or errors in writing.

The Possessive Apostrophe

A possessive apostrophe is a punctuation mark that is used to indicate ownership or possession. Pretend you have a dog named Charlie. If you wanted to talk about Charlie’s toy, you would use a possessive apostrophe to indicate the toy belongs to Charlie. You would write “Charlie’s toy”.

Perhaps you have a friend called Emily, and she owns a bike. If you wanted to describe Emily’s bike, you would use a possessive apostrophe to show she owns the bike. You would write “Emily’s bike”.

Notice how he possessive apostrophe is positioned between the name and the “s” to indicate an individual owns the possession in both of these examples. Where do you place the apostrophe is the object or thing belongs to more than one person?

Apostrophes of Contraction

Apostrophes can also be used to show that letters have been left out of a word. This is called a contraction. For example, instead of writing “do not,” you can write “don’t.” The apostrophe in “don’t” shows that the letter “o” has been left out of the word “do.”

You might use contractions when you’re texting with friends or writing informally, but you should avoid using them in more formal writing, such as writing an essay for school.

Conclusion

Some of the examples are deliberately difficult, so don’t worry if you made some mistakes. Try to explain why you added an apostrophe when one wasn’t actually required, or why you placed the apostrophe in the wrong position. This is the best way to develop your understanding of apostrophes and how they add clarity to your writing.
