The Smiths or The Smiths’ or The Smiths’s? Which Is Correct?

The Smiths or The Smiths’ or The Smiths’s can seem confusing, but the correct form depends on grammar and meaning. The Smiths is the plural form of the last name or surname Smith. Use it when referring to two or more people from the Smith family. It can describe the parents, children, or the whole family. For example, The Smiths have two daughters and one son. When addressing a Christmas Card, write The Smiths. Here, Smiths works as a plural noun, not a possessive form.

Use Smiths’ when you want to show possession or ownership. The apostrophe comes after the plural Smiths, because something belongs to two or more people. For example, The Smiths’ dog chased our cat up a tree. The noise kept me awake until 2 a.m. At their New Year’s Eve party, Smiths’ cars and Jones’ cars collided in the driveway, causing a collision. This simple pattern makes the possessive form easier to recognize.

Other examples make the difference even clearer. Johnny is one of the Smiths living on Second Street. A roofer discovered raccoons living in the Smiths’ attics and told the family about health and safety risks linked to removing the animals. Their address is on that street. In normal usage, Smiths’s isn’t the standard choice for this family name. The plural Smiths and possessive Smiths’ are the forms you usually need.

Quick Answer

The correct form depends on what you mean.

Form	What it means	Example
The Smiths	The Smith family or multiple people named Smith	The Smiths are coming to dinner.
The Smiths’	Something belonging to the Smith family	The Smiths’ house is beautiful.
Smith’s	Something belonging to one person named Smith	Smith’s car is outside.
The Smiths’s	Nonstandard plural possessive form	Avoid The Smiths’s in standard English.

The easiest rule is this:

The Smiths = the family. The Smiths’ = something belonging to the family.

If you’re talking about one individual, use Smith’s for possession.

For example:

• The Smiths are visiting us.
• The Smiths’ car is parked outside.
• Smith’s car is parked outside.

Notice how the apostrophe changes the grammatical function rather than simply changing the spelling.

What Does “The Smiths” Mean?

The Smiths is the plural form of the surname Smith. You use it when referring to two or more people who share that surname.

When you talk about a family as a group, you normally put the before the plural surname.

For example:

• The Smiths live next door.
• We invited the Smiths to dinner.
• The Smiths are moving next month.
• I saw the Smiths at the grocery store.
• The Smiths have three children.

In each sentence, Smiths identifies the people themselves. Nothing belongs to them grammatically in these examples.

That’s why you don’t need an apostrophe.

Why “The Smith’s” Is Wrong for the Whole Family

A common mistake is writing The Smith’s when referring to the Smith family.

For example:

❌ The Smith’s are coming over.

✅ The Smiths are coming over.

The apostrophe in Smith’s makes the name singular possessive. It doesn’t normally make a surname plural.

Think of it this way:

Smith → one person
Smiths → more than one person

An apostrophe doesn’t create the plural.

This distinction matters because Smith’s and Smiths perform different grammatical jobs.

When Should You Use “The Smiths’”?

Use The Smiths’ when something belongs to, relates to, or is associated with the Smith family.

The formation is simple:

The Smiths → The Smiths’

You already have the plural surname Smiths. Since it ends in s, you add only an apostrophe to make it possessive.

Consider these examples:

• The Smiths’ house is across the street.
• The Smiths’ dog escaped yesterday.
• The Smiths’ children attend the local school.
• We borrowed the Smiths’ lawn mower.
• The Smiths’ vacation starts tomorrow.
• I attended the Smiths’ anniversary party.

The apostrophe tells the reader that the following noun has a relationship with the Smith family.

The Smiths’ Doesn’t Always Mean Physical Ownership

Possession in grammar doesn’t always mean someone literally owns an object.

For example:

The Smiths’ children

The children aren’t possessions. The phrase describes their relationship to the Smith family.

Likewise:

• The Smiths’ wedding
• The Smiths’ plans
• The Smiths’ reputation
• The Smiths’ business
• The Smiths’ neighborhood

The apostrophe can therefore express ownership, association, relationship, responsibility, or connection.

That’s an important detail because the grammatical term possessive is broader than everyday ownership.

Why “The Smiths’s” Is Not the Standard Form

The Smiths’s looks tempting because singular names generally form possessives with ’s.

For example:

• Smith → Smith’s
• John → John’s
• teacher → teacher’s

However, Smiths is already plural.

The standard pattern for a plural noun ending in s is to add an apostrophe after the existing s.

So:

Smith → Smiths → Smiths’

Not:

Smith → Smiths → Smiths’s

Compare the forms:

Number	Noun	Possessive
Singular	Smith	Smith’s
Plural	Smiths	Smiths’

This distinction explains why The Smiths’s house isn’t the standard choice.

The correct sentence is:

✅ The Smiths’ house is large.

The same principle appears with ordinary plural nouns:

• students → students’
• teachers → teachers’
• players → players’
• parents → parents’
• Smiths → Smiths’

The underlying rule remains consistent.

What’s the Difference?

This is one of the most important distinctions in the entire topic.

Smith’s refers to possession by one Smith.

The Smiths’ refers to possession by multiple Smiths, usually the family.

Compare these sentences:

Smith’s car is new.

One person named Smith owns or uses the car.

The Smiths’ car is new.

The Smith family owns or uses the car.

The difference may seem tiny on the page. Grammatically, however, it tells you who the possessor is.

More Examples

Singular:

• Smith’s office is upstairs.
• Smith’s phone is ringing.
• Smith’s daughter is studying abroad.
• Smith’s idea impressed everyone.

Plural possessive:

• The Smiths’ office is upstairs.
• The Smiths’ phone was found in the car.
• The Smiths’ daughter is studying abroad.
• The Smiths’ idea impressed everyone.

In the second group, the family or multiple people named Smith possess or relate to the following noun.

The Difference Between “The Smiths” and “The Smiths’”

The easiest way to understand the apostrophe is to compare two sentences.

The Smiths

The Smiths are at home.

Here, The Smiths functions as the subject of the sentence. It refers to the people themselves.

The Smiths’

The Smiths’ house is at the end of the street.

Here, The Smiths’ identifies who the house belongs to or is associated with.

The difference becomes even clearer in this pair:

• The Smiths bought a new car.
• The Smiths’ new car is blue.

In the first sentence, The Smiths performs the action.

In the second sentence, The Smiths’ modifies car.

That tiny apostrophe carries real grammatical information.

How to Make “Smith” Plural

Making Smith plural is straightforward.

Simply add s:

Smith → Smiths

When referring to the family, add the:

the Smiths

For example:

• The Smiths are visiting.
• We met the Smiths yesterday.
• The Smiths moved into the house.
• Everyone invited the Smiths.

The important point is that Smiths doesn’t need an apostrophe simply because it’s a surname.

Don’t Use an Apostrophe to Create the Plural

This mistake appears frequently in family names.

Incorrect:

❌ The Smith’s are here.

Correct:

✅ The Smiths are here.

The first version suggests possession by one Smith. The second refers to the family.

The same distinction applies to other surnames:

• The Johnsons, not The Johnson’s
• The Millers, not The Miller’s
• The Taylors, not The Taylor’s
• The Bakers, not The Baker’s

The apostrophe has a job. It shouldn’t be recruited merely to make a name plural.

How to Make a Plural Family Name Possessive

Once you understand the plural form, the possessive becomes much easier.

Follow these two steps:

1. Make the surname plural.
2. Add an apostrophe after the final s.

For Smith, that gives you:

Smith → Smiths → Smiths’

Now apply the pattern:

• The Smiths’ house
• The Smiths’ car
• The Smiths’ garden
• The Smiths’ children
• The Smiths’ business

The same structure works with many ordinary plural surnames.

Family name	Plural family name	Possessive
Smith	Smiths	Smiths’
Johnson	Johnsons	Johnsons’
Miller	Millers	Millers’
Taylor	Taylors	Taylors’
Baker	Bakers	Bakers’
Carter	Carters	Carters’

This pattern is especially useful when writing invitations, family announcements, signs, and formal correspondence.

What About Surnames That Already End in S?

Things become slightly more interesting when the original surname already ends in s.

Consider Jones.

If you’re talking about the Jones family, the standard plural form is Joneses.

So the progression becomes:

Jones → Joneses → Joneses’

For example:

• The Joneses are coming over.
• The Joneses’ house is nearby.

The same principle applies to other surnames that end in s.

Examples include:

• Williams → Williamses → Williamses’
• Harris → Harrises → Harrises’
• Collins → Collinses → Collinses’

The important detail is that the original surname’s final s doesn’t automatically make the family name plural.

You first form the appropriate plural. Then you make that plural possessive.

Compare Smith and Jones

Surname	Family plural	Family possessive
Smith	Smiths	Smiths’
Jones	Joneses	Joneses’
Williams	Williamses	Williamses’
Harris	Harrises	Harrises’

This is why surname spelling deserves a little care. The same possessive principle applies, but the plural form can change.

The Smiths’ House vs. The Smith Family’s House

You can also write:

The Smiths’ house is beautiful.

Or:

The Smith family’s house is beautiful.

Both constructions can express the same basic idea.

The difference lies in how the sentence is structured.

In The Smiths’ house, Smiths is the plural family surname.

In The Smith family’s house, family is the noun that takes the possessive ending.

This also explains why you shouldn’t write:

❌ The Smiths family

Instead, use:

✅ The Smith family

or

✅ The Smiths

The word family already identifies the group. You don’t need to pluralize Smith in Smith family.

Common Mistakes

Several errors appear repeatedly when people write family names.

Writing “The Smith’s” for the Family

❌ The Smith’s are coming tonight.

✅ The Smiths are coming tonight.

The apostrophe doesn’t create a plural surname.

Writing “The Smiths’s”

❌ The Smiths’s car is outside.

✅ The Smiths’ car is outside.

The plural surname already ends in s, so the possessive requires only an apostrophe.

Leaving Out the Apostrophe When Possession Matters

❌ The Smiths house is beautiful.

✅ The Smiths’ house is beautiful.

Without the apostrophe, Smiths simply appears as a plural noun modifying house. Standard possessive punctuation requires the apostrophe.

Using “Smith’s” for the Whole Family

❌ We invited Smith’s to dinner.

If you mean the family, use:

✅ We invited the Smiths to dinner.

If you mean one person named Smith, the sentence needs a different structure.

“The Smiths” on a Family Sign

A practical question often arises around signs, invitations, and home decorations.

Should the sign say:

The Smiths

or

The Smiths’

Usually, The Smiths is the better choice when the sign simply identifies the people or household.

For example:

The Smiths

works like a family label.

It doesn’t need to show possession because no noun follows it.

However, if you write:

The Smiths’ Home

the apostrophe makes sense because home belongs to or is associated with the Smiths.

Compare:

• The Smiths — identifies the family.
• The Smiths’ Home — expresses possession.
• The Smiths’ Garden — expresses possession.
• Welcome to the Smiths — identifies the family.

The apostrophe belongs where the grammar requires possession.

Is “The Smiths’” Always About Ownership?

No. The possessive construction can show several relationships.

Consider these examples:

• The Smiths’ children
• The Smiths’ wedding
• The Smiths’ plans
• The Smiths’ business
• The Smiths’ neighborhood
• The Smiths’ anniversary

1. In The Smiths’ children, the phrase expresses family relationship.

2. In The Smiths’ wedding, it identifies the couple’s wedding.

3. In The Smiths’ plans, it identifies plans associated with the family.

So don’t interpret possessive too literally. English uses possessive forms for many kinds of relationships.

A Simple Rule for Remembering 

If apostrophes make your head spin, use this quick test.

Ask yourself:

Am I talking about the people?

If yes, use:

The Smiths

Example:

The Smiths are having dinner.

Then ask:

Am I talking about something connected to or belonging to them?

If yes, use:

The Smiths’

Example:

The Smiths’ dinner starts at seven.

For one person, use:

Smith’s

Example:

Smith’s dinner starts at seven.

The entire rule can be reduced to this:

One Smith → Smith’s
Several Smiths → Smiths’

That distinction solves most problems immediately.

Quick Comparison: Smith, Smiths, Smith’s, and Smiths’

The following table brings the entire rule together.

Form	Number	Function	Meaning	Example
Smith	Singular	Noun	One person	Smith arrived early.
Smiths	Plural	Noun	Multiple people	The Smiths arrived early.
Smith’s	Singular	Possessive	Belonging to one Smith	Smith’s coat is wet.
Smiths’	Plural	Possessive	Belonging to multiple Smiths	The Smiths’ coats are wet.
Smiths’s	Plural	Nonstandard possessive	Not the standard form	Avoid it in standard usage.

This distinction becomes much easier once you separate number from possession.

First determine whether you’re talking about one person or several.

Then determine whether you’re showing possession.

That two-step approach prevents most apostrophe mistakes.

Examples of “The Smiths” in Sentences

Here are practical examples you can use as a reference.

Referring to the Family

• The Smiths are hosting dinner tonight.
• We visited the Smiths last weekend.
• The Smiths moved into the neighborhood.
• Everyone knows the Smiths.
• The Smiths have two children.

No apostrophe appears because The Smiths simply identifies the family.

Showing Possession

• The Smiths’ house has a red door.
• I borrowed the Smiths’ lawn mower.
• The Smiths’ dog escaped yesterday.
• The Smiths’ children attend the local school.
• We admired the Smiths’ garden.

The apostrophe appears because the phrase expresses a relationship with the Smith family.

Referring to One Smith

• Smith’s office is on the second floor.
• Smith’s car needs repairs.
• Smith’s daughter called earlier.
• Smith’s idea changed the project.

Here, Smith’s refers to one individual.

A Practical Case Study: Writing About a Family

Imagine you’re writing an invitation for a neighborhood dinner.

You want to say that the Smith family will attend.

The correct sentence is:

The Smiths will join us for dinner.

Now you want to mention their car.

You write:

The Smiths’ car will be parked outside.

Now imagine you’re referring to Mr. Smith alone.

You would write:

Smith’s car will be parked outside.

Three nearly identical forms now have three different meanings:

Sentence	Who does it refer to?
The Smiths will arrive soon.	The family
The Smiths’ car will arrive soon.	The family owns or uses the car
Smith’s car will arrive soon.	One Smith owns or uses the car

This is why punctuation isn’t merely decorative. A small apostrophe can change who you’re talking about.
