Quick Answer: The Smiths, The Smiths’, or The Smiths’s?

Here’s the short version:

Form	Meaning	Example
The Smiths	More than one member of the Smith family	The Smiths live next door.
The Smiths’	Something belongs to the Smith family	The Smiths’ house is beautiful.
The Smiths’s	Usually incorrect when referring to the whole Smith family	Rarely appropriate in this context.

Most of the confusion comes from mixing up plural forms and possessive forms.

Before deciding which version to use, ask yourself a simple question:

Are you talking about the family itself or something that belongs to the family?

The answer determines the correct spelling.

Understanding the Difference Between Plural and Possessive Nouns

Many grammar mistakes happen because plural and possessive nouns look similar.

However, they serve completely different functions.

A Plural Noun

A plural noun refers to more than one person, place, thing, or idea.

Examples:

• Dog → Dogs
• Teacher → Teachers
• Smith → Smiths

When talking about the entire Smith family, Smiths is simply the plural form.

Example:

The Smiths are hosting a barbecue this weekend.

Nothing belongs to anyone here. You’re merely referring to multiple members of the Smith family.

A Possessive Noun

A possessive noun shows ownership.

Examples:

• The dog’s leash
• The teacher’s classroom
• The Smiths’ backyard

The apostrophe indicates that something belongs to someone.

This distinction forms the foundation of every rule discussed below.

When to Use “The Smiths”

The Smiths is the correct form when you’re referring to the family as a group.

Think of it as the plural version of Smith.

Examples

• The Smiths moved to Texas last year.
• The Smiths enjoy traveling together.
• We had dinner with the Smiths.
• The Smiths are celebrating their anniversary.

Notice something important.

There is no apostrophe.

You’re not showing ownership. You’re simply naming a family consisting of multiple people who share the surname Smith.

Common Uses

You typically use The Smiths in:

• Family introductions
• Holiday cards
• Wedding invitations
• Address labels
• Neighborhood conversations

Examples:

• Merry Christmas from the Smiths!
• Welcome, The Smiths!
• We visited the Smiths over the weekend.

Whenever you’re talking about the family itself, use The Smiths.

When to Use “The Smiths’”

The Smiths’ is the possessive form of the plural noun Smiths.

This means something belongs to the Smith family collectively.

The Rule

First make the noun plural:

• Smith → Smiths

Then add an apostrophe:

• Smiths → Smiths’

Because the word already ends in s, you place the apostrophe after the final s.

Examples

• The Smiths’ home was recently renovated.
• The Smiths’ vacation photos looked amazing.
• The Smiths’ dog loves visitors.
• The Smiths’ garden won first place.

In each sentence, something belongs to the entire Smith family.

Visual Breakdown

Family	Ownership
The Smiths	The Smiths’ house
The Johnsons	The Johnsons’ car
The Williamses	The Williamses’ boat

This pattern remains consistent regardless of the family name.

Why “The Smiths’s” Is Usually Incorrect

Many people assume that every possessive noun requires an apostrophe followed by s.

That isn’t always true.

When a plural noun already ends in s, standard grammar rules typically require only an apostrophe.

Incorrect

• The Smiths’s house
• The Smiths’s dog
• The Smiths’s vacation

Correct

• The Smiths’ house
• The Smiths’ dog
• The Smiths’ vacation

The reason is simple.

The word Smiths already ends with an s because it’s plural.

Adding another s after the apostrophe creates an awkward and unnecessary construction.

The One Situation Where “Smith’s” Is Correct

A different rule applies when referring to a single person named Smith.

Examples

• Mr. Smith’s office
• John Smith’s car
• Sarah Smith’s laptop
• Smith’s presentation

Here, only one individual owns the object.

The possessive form becomes:

Smith + ’s = Smith’s

Comparison Table

Meaning	Correct Form
One person named Smith	Smith’s
Entire Smith family	Smiths
Something owned by the Smith family	Smiths’

This distinction eliminates much of the confusion.

Real-World Examples of Correct Usage

Let’s examine situations people encounter every day.

Holiday Cards

Correct:

Happy Holidays from the Smiths!

Incorrect:

Happy Holidays from the Smith’s!

Why?

You’re identifying the family, not showing ownership.

Family Mailbox Signs

Correct:

The Smiths

Incorrect:

The Smith’s

A mailbox displays the family’s name.

Ownership isn’t the focus.

Family Property

Correct:

The Smiths’ lake house

Correct:

The Smiths’ driveway

Correct:

The Smiths’ vacation cabin

These items belong to the family collectively.

Neighborhood Conversation

Correct:

The Smiths moved in last month.

The Smiths’ new fence looks great.

The first sentence refers to the family.

The second refers to something they own.

The Grammar Rule Behind Family Names

English follows a straightforward process when creating possessives from family names.

Step 1: Make the Name Plural

Smith → Smiths

Jones → Joneses

Williams → Williamses

Brown → Browns

Step 2: Add Possession If Needed

Smiths → Smiths’

Joneses → Joneses’

Williamses → Williamses’

Browns → Browns’

That’s it.

The process remains consistent across most surnames.

Family Names That End in S

Names ending in s often create the most confusion.

Consider these examples:

• Jones
• Williams
• Harris
• Adams
• Brooks

Many writers aren’t sure whether they should add an apostrophe, apostrophe-s, or something else entirely.

Correct Plural Forms

Singular Name	Plural Family Name
Jones	Joneses
Williams	Williamses
Harris	Harrises
Adams	Adamses
Brooks	Brookses

Correct Possessive Forms

Family Name	Possessive Form
Joneses	Joneses’
Williamses	Williamses’
Harrises	Harrises’
Adamses	Adamses’
Brookses	Brookses’

The same principle used for The Smiths’ applies here.

AP Style vs Chicago Style: Is There a Difference?

Different style guides occasionally approach possessives differently.

Fortunately, family possessives remain largely consistent.

AP Style

AP Style generally recommends:

• Singular noun: add ’s
• Plural noun ending in s: add apostrophe only

Examples:

• Smith’s report
• The Smiths’ house

Chicago Manual of Style

Chicago reaches the same conclusion for plural possessives.

Examples:

• The Smiths’ property
• The Joneses’ car

As a result, you rarely encounter disagreement when writing about family ownership.

Common Mistakes People Make

Certain errors appear repeatedly in emails, invitations, social media posts, and signage.

Mistake #1: Using an Apostrophe for Plurals

Incorrect:

The Smith’s are coming over tonight.

Correct:

The Smiths are coming over tonight.

An apostrophe never creates a plural noun.

Mistake #2: Adding Extra Letters

Incorrect:

The Smiths’s dog escaped.

Correct:

The Smiths’ dog escaped.

The plural already ends in s.

No additional s is needed.

Mistake #3: Mislabeling Holiday Cards

Incorrect:

Merry Christmas from the Smith’s

Correct:

Merry Christmas from the Smiths

This is one of the most common grammar mistakes seen every holiday season.

Mistake #4: Mixing Singular and Plural Possession

Incorrect:

The Smith’s house

when referring to the entire family.

Correct:

The Smiths’ house

The family owns the house collectively.

The Smiths’ car is parked outside.

This quick check solves most possessive problems instantly.
