Apostrophes. We all use them. But we don't all use them correctly.
An apostrophe "s" is used to show possession.
Girl: Bleh-bleh-bleh!
Not that type of possession. More like ownership of an object.
For instance, that's Sarah's dog. [dog barks] The apostrophe "s" indicates that the dog belongs to Sarah.
Without the apostrophe, "Sarah's" would become "Sarahs", the plural of Sarah.
Girl: Mwa-ha-ha-ha! An army of Mes!
Let me fix that.
Now, suppose Sarah and her sister, Margery, both had pets. [pets growl] They would be the sisters'
pets. The apostrophe comes after the "s".
This is called plural possession.
Girls: Bleh-bleh-bleh!
No, not like that.
Plural possession is when more than one subject possesses something.
"The sisters' pets" is an example of plural possession.
"Her sister's pet" is an example of singular possession.
Let's sum it up.
