Question

How to use apostrophes​

Answer 1

You use them to kind of combine words.

For example, instead of saying, "They have stolen my dog", you can say, "They've stolen my dog".

More examples:

Have not - Haven't

Is not - Isn't

I will - I'll

You can also use them to show that someone owns something.

For example, "Sarah's cat". This shows that she owns a cat.

I tried my best to explain it.

Answer 2

Use an apostrophe + S ('s) to show that one person/thing owns or is a member of something. ...
Use an apostrophe after the "s" at the end of a plural noun to show possession. ...
If a plural noun doesn't end in "s," add an apostrophe + "s" to create the possessive form.
