Sisters or Sister’s or Sisters’? Which is correct?

Grammar / By

Sisters is the plural for sister. Sister’s is the singular possessive form of sister. Sisters’ is the plural possessive form of sisters. 

Sisters or Sister’s or Sisters’ are all pronounced the same way in English but they are used in different contexts.

Sisters

We use sisters when we want to make the word “sister” plural.

So it is:

I have one sister.

I have two sisters. 

Sister’s 

Sister’s is the possessive form of sister. We use the possessive form of sister when we want to show that one sister owns something.

This is my Sister’s house.

We need to look after our Sister’s plant.

Remember we are talking about only one Sister. You can replace sister’s with a name if that makes it easier to understand.

This is Jane’s house.

We need to look after Jane’s plant.

Sisters’ 

Sisters’ is the possessive form of sisters. When the noun already ends in “s” and we want to make the word possessive, we need to put the apostrophe after the “s”.

This is our Sisters’ house.

In this case, many of our sisters live in the house and they own the house together.

In spoken English, it can be difficult to know whether you are talking about one sister or many sisters in the possessive because sister’s and sisters’ sound exactly the same.

What is the difference between Sister’s and Sisters?

Sisters is simply the plural of the word sister. Sister’s is the singular possessive of Sister which means that your Sister owns something.

Is Sister’s plural?

No, “Sister’s” is not plural. It is the possessive form of Sister. “Sisters” is the plural of “Sister”.
