Possessive nouns indicate ownership or a close relationship, and at WHAT.EDU.VN, we’re here to make understanding them simple. Possessive nouns typically use an apostrophe (‘) and the letter ‘s’ to show this connection. If you’re struggling with possessive forms or need a quick refresher on grammar rules, look no further. Understand possessive case, possessive adjectives and prepositional phrases easily with this guide.
1. What Is A Possessive Noun?
Possessive nouns are nouns that demonstrate ownership or a direct connection. These nouns usually add an apostrophe (‘) and the letter “s” at the end of the word to create the possessive form. Almost any noun can become possessive, including abstract nouns.
- dog -> dog’s
- Maria -> Maria’s
- The Empire State Building -> The Empire State Building’s
Pay close attention to the apostrophe. In English, adding “s” to the end of a word often makes it plural. The apostrophe determines whether a noun is possessive or plural, such as “boys” versus “boy’s”. “Boys” refers to more than one boy (plural), while “boy’s” indicates that one boy owns something (singular possessive).
Possessive nouns are followed by the object of the possession. For example:
There are three books on Kali’s desk.
In this case, Kali owns the desk. The object of possession is usually the first noun after the possessive noun, often immediately after it. However, adjectives can be included to describe the object:
Kali’s messy desk has been cluttered for as long as I’ve known her.
Possessive nouns can also show a relationship between two people or between a person and a place or idea. For example, “Sally’s husband” and “Tahiv’s cosmic theory” both contain possessive nouns.
1.1 What is the Possessive Case?
The possessive case shows ownership (Sanjay’s phone) or a direct connection (Sanjay’s sister).
Here are a few examples of possessives in a sentence:
Aiguo grabbed his hat from Tony’s car.
This sentence contains two possessives. The possessive adjective “his,” referring to Aiguo, indicates ownership of the hat. The possessive noun “Tony’s,” marked by the “’s,” indicates ownership of the car.
1.2 What is a Possessive Adjective?
Like possessive nouns, possessive adjectives indicate ownership or a direct connection. They align with English pronouns, matching person, gender, and number.
Additionally, the possessive adjective “whose” serves as the possessive form of the relative pronoun “who” and introduces relative phrases and clauses.
Unlike possessive nouns, possessive adjectives do not use apostrophes. This is especially important for the possessive adjective “its,” often confused with the contraction “it’s,” meaning “it is.”
1.3 Prepositional Alternatives
Ownership or connection can also be shown using the preposition “of,” without possessive nouns.
Shaima revered the desk of Kali.
In this instance, the owner (Kali) is the object of a prepositional phrase with “of,” and the owned item (the desk) comes first. This construction doesn’t require an apostrophe or the letter “s.”
Sentences constructed this way often highlight the object rather than its owner. In the example above, positioning the desk as the focal point emphasizes Shaima’s reverence for it. This construction is often found in academic and formal contexts, conveying a formal tone.
1.4 What are the Four Types of Possessive Nouns?
There are four types of possessive nouns:
- Singular possessive nouns: Standard singular nouns made possessive by adding an apostrophe and the letter “s.” Example: We rode in Javier’s car.
- Plural possessive nouns: Plural nouns ending in “s” made plural by adding an apostrophe after the “s.” Example: It was the students’ last day.
- Possessive pronouns: Pronouns standing in for possessive nouns, following antecedents to make sentences flow more smoothly. Example: Derek offered Brenda a soda, which was in his refrigerator.
- Irregular possessive nouns: Irregular nouns like “teeth” become irregular possessive nouns by following unique rules. Example: The heroes’ capes are yellow.
2. Singular Possessive Nouns Explained
Singular possessive nouns are regular nouns that become possessive by adding an “’s.” They are the most basic form of possessive nouns.
The formula for singular possessive nouns is: [singular noun] + [’s]
Nouns ending in “s,” especially proper nouns, can be confusing. However, it is acceptable to add an “’s” after an “s” if the noun is singular (the boss’s chair).
This includes both mass nouns and collective nouns. Mass nouns are uncountable and don’t have a plural form, like “sand” or “money.” Collective nouns are singular but represent multiple things, like “team” or “family.”
2.1 Examples of Singular Possessive Nouns
Carlos’s school is three miles away.
The soccer team’s captain was injured in a game.
Studying economics helped me understand money’s value.
I adjusted the dog’s collar.
Shira and Kyle planned Amit’s birthday party.
3. Plural Possessive Nouns Explained
Plural possessive nouns are plural nouns that end in “s.” These nouns are more challenging to make possessive because they already have an “s” at the end. The correct construction adds only an apostrophe to the end.
The formula for plural possessive nouns is: [plural noun] + [’]
However, proper nouns and general nouns that end in “s,” like “Carlos” or “class,” still use “’s.”
3.1 Examples of Plural Possessive Nouns
The glasses are under the bottles’ shelf.
It was perfect weather for the teams’ tournament.
You’ll need at least three years’ experience for this role.
The monkeys’ calls rang out through the canopy.
Her company designed the books’ covers.
4. Possessive Pronouns Explained
Possessive pronouns are the noun form of pronouns that show possession. Like regular pronouns, they replace other nouns to avoid repetition.
Unlike other possessive nouns, possessive pronouns do not come before the object of possession. Usually, what a pronoun refers to is mentioned earlier, and the possessive pronoun is used instead of repeating the original word.
Be careful not to confuse possessive pronouns with possessive adjectives. Possessive pronouns act as nouns, not adjectives.
Mine computer has caused me nothing but trouble. (Incorrect)
That computer of mine has caused me nothing but trouble. (Correct)
4.1 Examples of Possessive Pronouns
I don’t have a calculator. Can I borrow yours?
I wish I had hair like hers.
Sarah’s parking spot is closer than mine.
Their house isn’t as nice as ours.
Our vacation is in September. When is theirs?
5. Irregular Possessive Nouns Explained
Not all nouns become plural by adding “s.” Irregular plural nouns, like “children” or “teeth,” have unique plural forms. The possessive form of irregular plural nouns depends on whether or not they already end in an “s.”
- If the irregular plural noun has an “s” at the end, add only an apostrophe. Example: knives’ handles
- If the irregular plural noun does not have an “s” at the end, add both an apostrophe and an “s.” Example: teeth’s reflection
5.1 Examples of Irregular Possessive Nouns
We followed them back to the geese’s flock. (singular: goose’s flock)
That’s the site of the wolves’ den. (singular: wolf’s den)
We enjoyed a heroes’ feast. (singular: hero’s feast)
The band played children’s music. (singular: child’s music)
The tomatoes’ color was vibrant. (singular: tomato’s color)
6. Key Possessive Noun Rules
Possessive nouns follow consistent rules to ensure their meanings are clear. These rules are especially important in sentences containing compound possessives or hyphenated possessive nouns.
6.1 Forming Possessives with Two or More Nouns
Forming a possessive with two or more nouns depends on whether the nouns relate to the same or different things. These are known as compound possessives.
If multiple nouns own or connect to the same object, only the last one in the series is possessive.
We watched Karlie and Jessie’s band play.
That’s the soccer team and field hockey team’s field.
If two or more nouns each own different versions of something, make each separate noun possessive.
We visited the science teacher’s and art teacher’s rooms.
America’s and Canada’s political policies are aligned.
Julie’s and Juanita’s cats are black.
In these examples, the objects of possession are also plural (rooms, policies, cats) because there’s more than one.
6.2 Forming Possessives with Hyphenated and Compound Nouns
Hyphenated and compound nouns can seem tricky, but they’re quite simple. If they’re singular, add an apostrophe and an “s” to the final word.
They raised the trash can’s lid.
I love my mother-in-law’s cooking.
If the nouns are plural with a regular “s” at the end, add only an apostrophe to the final word.
He’s always reading news blogs’ articles.
X-rays’ images are a critical diagnostic tool.
If the word is plural without an “s” at the end, add both an apostrophe and an “s” to the final word.
We both examined our mothers-in-law’s behaviors.
These are the academically advanced children’s textbooks.
6.3 Adding Emphasis with the Adjective “Own”
Use the adjective “own” before the object of possession to add special emphasis, drawing attention to the ownership or connection.
Abel’s own brother betrayed him!
Napoleon’s own mansion is now a national museum.
I was so proud that my own team showed up for my award.
After moving in, they built their own garden.
Can you believe she ratted out her own sister?
7. Common Mistakes with Possessive Nouns
Familiarizing yourself with common mistakes writers make with possessive nouns can help you avoid them.
7.1 Its vs. It’s
Unlike other possessive pronouns, the possessive form of “it” is “its.” “It’s” (with the apostrophe) is a contraction for “it is.”
- Possessive: The duck flapped its wings.
- Contraction: I should go. It’s getting late.
7.2 Singular vs. Plural Possessives
Singular possessive nouns end with an apostrophe plus “s.” Plural possessive nouns that end in “s” end with an apostrophe after the “s.”
- Singular: The boy’s shirt was red.
- Plural: The boys’ shirts were red.
7.3 Overuse of Possessive Forms
Possession can also be shown with the possessive form “of.” For example, “of the dog” instead of “dog’s.” This isn’t grammatically incorrect but can be awkward if used excessively.

8.3 When Should You Use Possessive Nouns?
Use possessive nouns to communicate the relationship between two nouns, such as a person and an item they own, two people, or a person and an idea. Example: Emma’s book is on the table.
8.4 Can You Use Possessive Nouns with Inanimate Objects?
Possessive nouns can be used with inanimate objects, especially to indicate a direct connection or ownership. However, in some formal or academic writing, prepositional phrases like “the engine of the car” may be preferable. Examples: The car’s engine or The book’s cover.
8.5 How Do You Use Possessives with Joint Ownership?
If two or more nouns jointly own something, only the final noun should be in the possessive form. Example: Jake and Emily’s house (they share one house). If each noun owns something separately, make each noun possessive: Jake’s and Emily’s houses (two different houses).
