What is the Possessive Case of Nouns?

The possessive case shows the relationship of a noun to other words in a sentence. That relationship can be ownership, possession, occupancy, a personal relationship, or another kind of association. With the addition of -‘s (or sometimes just the apostrophe), a noun can change from a simple person, place, or thing to a person, place, or thing with a relationship to something else. There are a few different ways to form the possessive of a noun. 

Examples:

  • Ali’s phone
  • The teacher’s desk

The possessive case of a noun is usually formed by adding ‘s to the noun. However, there are certain rules that you should know when forming the possessive case because it depends on the type of noun.

Possessive Forms of Singular Nouns

The possessive case of most singular nouns, whether common or proper, is formed by adding -‘s to the end. 

Examples:

  • boy’s bag
  • dog’s bone
  • car’s engine

Even if the noun ends in s, like class, you can still add ‘s at the end of the noun to make its possessive case. For instance:

  • class’s schedule

Here is the thing that you should keep in mind that some style guides allow just an apostrophe (‘) for a singular noun that ends in s. Here is an example:

  • James’s book
  • James’ book

Both forms are accepted; however, you should be consistent in your writing and choose one form and stick to it.

Possessive Forms of Plural Nouns

1. Plural Nouns Ending in -s

In case of plural nouns that end in s, we only add an apostrophe to make them possessive. See the following examples:

Examples:

  • students’ homework
  • teachers’ lounge

These two examples show the ownership of more than one person, which means the item or thing belongs to more than one person.

2. Irregular Plural Nouns (not ending in -s)

The possessive case of irregular plural nouns that do not end in s, we simply add ‘s, just like with singular nouns.

Examples:

  • children’s toys
  • men’s jackets
  • women’s shoes

Possessive Forms for Mulitple Nouns

When two or more nouns jointly possess one thing, change only the last noun to the possessive case:

Examples:

  • Ali and Sara’s house

They share one house.

When two or more nouns possess things individually that are being discussed together, change both/all nouns to the possessive case.

Examples:

  • Ali’s and Sara’s cars

Each has their own car.

Possessive Case with Names and Proper Nouns

When using people’s names or other proper nouns, follow the same basic rules as mentioned earlier:

For examples

  • Emma’s bag
  • Charles’ book
  • Pakistan’s culture

Possessives Vs. Appositives

Many times, if the nouns showing a relationship to another word in a sentence is a building, an object, or a piece of furniture, it doesn’t need to be a possessive at all; it can instead be an appositive.

Examples:

  • The housekeeper cleaned the hotel room.
  • We met in the office lobby.
  • Shut the car door.
