Definition of Possessive ‘S’
The possessive ‘s’, also known as the genitive case, is a grammatical construction used in English to indicate ownership, relationship, or association. It is typically formed by adding an apostrophe and the letter ‘s’ (‘s) to a noun.
This construction shows that the noun owns or is related to another noun. The possessive ‘s’ is an essential part of English grammar, enabling us to express connections between things and people concisely and clearly.
For example, instead of saying “the book that belongs to John,” we can simply say “John’s book.”
The function of the possessive ‘s’ extends beyond simple ownership. It can also indicate a relationship, such as “my brother’s friend,” or an attribute, such as “the company’s reputation.” Understanding the various functions of the possessive ‘s’ is crucial for accurate and effective communication.
It helps avoid ambiguity and ensures that your intended meaning is clearly conveyed.
In linguistic terms, the possessive ‘s’ is a clitic, a type of morpheme that is grammatically dependent on a host word. It attaches to the end of the noun phrase that it modifies.
The placement and form of the possessive ‘s’ can vary depending on whether the noun is singular, plural, or a proper noun, leading to specific rules and exceptions that must be understood for correct usage.
Structural Breakdown
The basic structure of the possessive ‘s’ involves adding an apostrophe and the letter ‘s’ to a noun. However, the specific form depends on whether the noun is singular or plural. For singular nouns, the structure is straightforward: Noun + ‘s. For example, “dog’s bone” indicates that the bone belongs to the dog.
For plural nouns ending in ‘s’, the structure is slightly different. In this case, only an apostrophe is added after the ‘s’: Plural Noun (ending in ‘s’) + ‘. For example, “the students’ books” indicates that the books belong to multiple students.
Irregular plural nouns, which do not end in ‘s’ (e.g., children, men, women), follow the same rule as singular nouns: Irregular Plural Noun + ‘s. For example, “the children’s toys” indicates that the toys belong to the children.
When dealing with compound nouns (e.g., mother-in-law), the possessive ‘s’ is added to the last word of the compound noun: Compound Noun + ‘s. For example, “my mother-in-law’s car” indicates that the car belongs to my mother-in-law.
Types of Possessive ‘S’
The possessive ‘s’ can be categorized based on the type of noun it modifies. Understanding these categories is crucial for applying the correct rules.
Singular Nouns
Singular nouns take the standard form of the possessive ‘s’: Noun + ‘s. This is the most common type of possessive construction.
Examples:
- The cat’s tail
- John’s car
- The company’s profits
- My friend’s house
Plural Nouns Ending in ‘S’
Plural nouns that already end in ‘s’ only require an apostrophe after the ‘s’: Plural Noun + ‘. This avoids the awkwardness of adding another ‘s’.
Examples:
- The students’ desks
- My parents’ house
- The dogs’ toys
- The Smiths’ car
Irregular Plural Nouns
Irregular plural nouns, which do not end in ‘s’, follow the same rule as singular nouns: Irregular Plural Noun + ‘s.
Examples:
- The children’s books
- The men’s restroom
- The women’s rights
- The people’s choice
Compound Nouns
For compound nouns, the possessive ‘s’ is added to the last word: Compound Noun + ‘s.
Examples:
- My brother-in-law’s car
- The commander-in-chief’s orders
- The attorney general’s opinion
- Someone else’s problem
Joint Possession
When two or more nouns jointly possess something, the possessive ‘s’ is added only to the last noun in the series: Noun + and + Noun + ‘s.
Examples:
- John and Mary’s house (John and Mary own the house together)
- Tom and Susan’s children (Tom and Susan are the parents together)
- Smith and Jones’ company (Smith and Jones jointly own the company)
Separate Possession
When two or more nouns possess separate items, each noun takes the possessive ‘s’: Noun’s + and + Noun’s.
Examples:
- John’s and Mary’s cars (John has his own car, and Mary has her own car)
- Tom’s and Susan’s offices (Tom has his own office, and Susan has her own office)
- Smith’s and Jones’ reports (Smith has his own report, and Jones has his own report)

Usage Rules
Using the possessive ‘s’ correctly involves understanding several rules and exceptions. These rules govern when and how to use the possessive ‘s’ based on the type of noun and the context of the sentence.
Animate vs. Inanimate Nouns
Generally, the possessive ‘s’ is used with animate nouns (nouns that refer to living beings), while the preposition ‘of’ is used with inanimate nouns (nouns that refer to non-living things). For example, we say “the dog’s bone” (animate) but “the cover of the book” (inanimate).
However, this rule is not absolute, and there are exceptions.
Exceptions to the Animate Rule
There are several exceptions to the rule of using ‘s’ only with animate nouns. These exceptions often involve inanimate nouns that are closely associated with people, places, or times.
- Time periods: Today’s weather, yesterday’s news, a week’s vacation
- Geographical locations: America’s economy, London’s attractions, the Earth’s atmosphere
- Organizations: The company’s profits, the government’s policies
- Vehicles: The car’s engine, the ship’s captain
- Expressions of value or measurement: A dollar’s worth, a mile’s distance
Omitting the Possessed Noun
In some cases, the possessed noun can be omitted if it is clear from the context. This is common with places like shops, houses, or workplaces. For example, “I’m going to the doctor’s” (omitting “office”).
Examples:
- “I’m going to the baker’s.” (omitting “shop”)
- “We met at Mary’s.” (omitting “house”)
- “He works at the veterinarian’s.” (omitting “clinic”)
Proper Nouns Ending in ‘S’
The treatment of proper nouns ending in ‘s’ can vary. Some style guides recommend adding only an apostrophe (e.g., Chris’ car), while others recommend adding ‘s (e.g., Chris’s car). Both forms are generally accepted, but consistency is key. For names ending in a /z/ sound, such as Moses, it’s more common to use only the apostrophe (Moses’).
Examples:
- James’s book or James’ book
- Chris’s house or Chris’ house
- Moses’ laws

Advanced Topics
For advanced learners, understanding more complex aspects of the possessive ‘s’ can further refine their grammar skills.
The Double Possessive
The double possessive, also known as the “post-possessive” or “oblique possessive,” is a construction that combines the possessive ‘s’ with the preposition ‘of’. It is used to indicate a selection from a group or to express familiarity or affection. The structure is: a/an/the + noun + of + noun’s.
Examples:
- A friend of John’s
- A book of my father’s
- That cousin of yours
Possessive Pronouns vs. Possessive ‘S’
It’s important to distinguish between possessive pronouns (e.g., mine, yours, his, hers, its, ours, theirs) and the possessive ‘s’. Possessive pronouns stand alone and do not modify a noun, while the possessive ‘s’ modifies a noun.
Examples:
- This book is mine. (possessive pronoun)
- This is John’s book. (possessive ‘s’)
- The car is hers. (possessive pronoun)
- That is Mary’s car. (possessive ‘s’)
FAQ
Here are some frequently asked questions about the possessive ‘s’.
- When should I use ‘of’ instead of ‘s?
Generally, use ‘of’ with inanimate nouns and ‘s with animate nouns. However, there are exceptions, such as when referring to time periods, geographical locations, or organizations. - How do I handle proper nouns ending in ‘s’?
You can either add an apostrophe and ‘s (‘s) or just an apostrophe (‘). Both forms are generally accepted, but be consistent. For names ending in a /z/ sound, using only the apostrophe is more common. - What if two people own something together?
If they own it jointly, add the possessive ‘s’ only to the last name: “John and Mary’s house.” If they own separate items, each name takes the possessive ‘s’: “John’s and Mary’s cars.” - Can I use the possessive ‘s’ with inanimate objects?
Yes, in certain cases. These include time periods (today’s weather), geographical locations (London’s attractions), organizations (the company’s profits), and expressions of value or measurement (a dollar’s worth). - What is the double possessive?
The double possessive (e.g., “a friend of John’s”) combines the possessive ‘s’ with the preposition ‘of’. It’s used to indicate a selection from a group or express familiarity. - How do I know when to omit the possessed noun?
Omit the possessed noun when it is clear from the context. This is common with places like shops, houses, or workplaces (e.g., “I’m going to the baker’s”). - What’s the difference between *its* and *it’s*?
“Its” is a possessive pronoun (e.g., “The dog wagged its tail”). “It’s” is a contraction of “it is” or “it has” (e.g., “It’s raining”). - When do I use the possessive ‘s’ with compound nouns?
Add the possessive ‘s’ to the last word of the compound noun (e.g., “My brother-in-law’s car”).
