Parties or Party’s: The Easy Difference Explained

Parties is the plural of party or the verb form of party, while party’s is the possessive form of party. Choose parties when you mean more than one party; use party’s when something belongs to one party.

Have you ever typed parties or party’s and stopped because both look right?

You are not alone. I have seen this mistake often when helping English learners improve their writing. The confusion usually comes from the apostrophe. Many writers think an apostrophe automatically means a plural word. In English, however, that is not how apostrophes work.

The difference between parties and party’s is simple once you know what the apostrophe does.

Parties usually means more than one party. It can also be the third-person singular form of the verb party. Party’s, on the other hand, shows possession or means party is or party has in some sentences.

For example, you might write, “Several parties attended the meeting.” But you would write, “The party’s leader gave a speech.”

This guide will show you exactly when to use each form. You will also see simple examples, common mistakes, and an easy memory trick.

Parties or Party’s: Quick Answer

Parties and party’s have different jobs in a sentence.

• Parties = more than one party.
• Party’s = something belongs to one party, or a contraction of party is or party has.

Examples

Two political parties joined the debate.

Here, parties means two political groups.

The party’s decision surprised everyone.

Here, party’s means the decision belongs to or was made by one party.

Compare these:

Word	Meaning	Example
Parties	More than one party	Several parties signed the agreement.
Party’s	Belonging to one party	The party’s leader spoke first.

The easiest rule is this: Use -ies for a plural. Use ’s for possession or a contraction.

The Origin and Background of Parties and Party’s

The word party has a long history in English.

It comes from Old French partie, which was related to the idea of a part, side, or group. Over time, English speakers began using party for a group of people who shared a purpose or took the same side.

Today, party has several meanings.

It can describe:

• A group involved in an agreement or legal matter
• A political organization
• A social gathering
• One side in a dispute
• A group of people traveling or acting together

The plural form follows an important English spelling rule.

When a noun ends in a consonant + y, the y usually changes to ies when forming the plural.

For example:

• party → parties
• city → cities
• country → countries
• family → families
• company → companies

But party’s is different because the apostrophe shows possession or contraction.

For example:

The party’s plans were announced yesterday.

The plans belong to one party.

This is why parties and party’s should not be treated as spelling variations. They are different grammatical forms.

Parties vs Party’s: Key Differences

The main difference is number and possession.

Parties is generally a plural noun. It tells you that there is more than one party.

Party’s usually refers to one party and shows that something belongs to it. It can also be a shortened form of party is or party has.

Term	Meaning	When to Use	Region/Context
Parties	More than one party	When referring to multiple parties	All forms of English
Party’s	Belonging to one party	To show possession	All forms of English
Party’s	Party is	As a contraction	Informal/general writing
Party’s	Party has	As a contraction	Informal/general writing

1. Parties as a plural noun

Use parties when you are talking about two or more parties.

The two parties reached an agreement.

Several parties attended the meeting.

Both political parties supported the proposal.

Here, there is no possession. You simply mean more than one party.

2. Party’s for possession

Use party’s when something belongs to one party.

The party’s policy has changed.

This means:

The policy of the party has changed.

Another example:

We disagreed with the party’s decision.

The decision belongs to or was made by one party.

3. Party’s as a contraction

Party’s can also be a shortened form of party is or party has.

For example:

The party’s ready to begin.

This means:

The party is ready to begin.

It can also appear with has:

The party’s announced its new policy.

This means:

The party has announced its new policy.

However, this use can sometimes sound awkward because party’s already commonly signals possession. In formal writing, it may be clearer to write party is or party has.

Which Form Should You Use?

Your choice depends on what you want to say.

For students and beginners

Use parties when you mean more than one party.

Three parties signed the contract.

Use party’s when something belongs to one party.

The party’s office is nearby.

This simple rule will solve most cases.

For professional and academic writing

Be extra careful with the apostrophe.

If you mean multiple groups, write parties.

The parties agreed to the terms.

If you mean something belonging to one group, write party’s.

The party’s position remained unchanged.

In formal writing, consider avoiding contractions such as party’s = party is when clarity matters.

Instead of:

The party’s responsible for the decision.

Write:

The party is responsible for the decision.

For legal writing

Both forms can appear, but parties is especially common because legal documents often refer to multiple people or organizations.

For example:

The parties agree to the terms of this contract.

When possession is needed:

Each party’s rights are protected under the agreement.

Common Mistakes With Parties or Party’s

These two forms are easy to confuse. Here are some mistakes to watch for.

Mistake 1: Using party’s as a plural

❌ Two party’s signed the agreement.

✅ Two parties signed the agreement.

Why?

You are talking about more than one party. You do not need an apostrophe.

Mistake 2: Using parties for possession

❌ The parties leader gave a speech.

✅ The party’s leader gave a speech.

Why?

The leader belongs to one party. Therefore, you need the possessive form party’s.

Mistake 3: Adding an apostrophe to every plural

❌ The political party’s met yesterday.

✅ The political parties met yesterday.

Apostrophes do not normally make nouns plural.

Remember:

Plural = parties

Possession = party’s

Mistake 4: Confusing party’s with parties’

There is another form worth knowing: parties’.

Use parties’ when something belongs to more than one party.

Compare:

The party’s leader spoke.

One party → party’s

The parties’ leaders spoke.

More than one party → parties’

This small apostrophe difference can change the meaning of a sentence.

Mistake 5: Confusing party’s with party is

Sometimes writers use party’s when they really need a clear formal phrase.

For example:

The party’s responsible for the agreement.

This can mean the party is responsible. In formal writing, it is often better to write:

The party is responsible for the agreement.

The full form removes possible confusion.

Seeing these words in real situations makes the difference easier to remember.

This is common in contracts because several people or organizations may be involved.

For one party:

The obligations belong to one party.

Parties, Party’s, and Parties’ Compared

These three forms are often confused, but the rule is straightforward.

Term/Variant	Meaning	Region/Context	Best Used When
Parties	More than one party	Standard English	Talking about multiple parties
Party’s	Belonging to one party	Standard English	Showing one party’s possession
Party’s	Party is / party has	Mainly general or informal writing	Using a contraction
Parties’	Belonging to multiple parties	Standard English	Showing possession by two or more parties

A quick comparison

The parties signed the contract.

Multiple parties.

The party’s lawyer reviewed the contract.

One party owns or is connected to the lawyer.

The parties’ lawyers reviewed the contract.

Multiple parties have lawyers.

This is the clearest way to see why the apostrophe matters.

Parties or Party’s: Data, Trends & Usage

Searches for “parties or party’s” usually come from people who are unsure about plural and possessive forms. The intent is mainly informational.

The confusion is not surprising. English uses -s, -es, -ies, and apostrophes for different grammatical purposes. Learners often remember that an apostrophe appears in possessive words but may not know when possession is actually being shown.

The word party is also common in several areas:

• Politics
• Law
• Business
• Contracts
• Social events
• Everyday conversation

That makes the distinction useful far beyond spelling exercises.

A useful trend in modern English learning is the focus on context-based grammar. Instead of memorizing isolated rules, learners can ask one simple question:

Am I talking about more than one party, or does something belong to a party?

That question often gives you the correct answer immediately.

Easy Memory Trick for Parties vs Party’s

Try this:

Parties = many

Party’s = one party’s thing

If you see -ies, think more than one.

The parties met.

If you see ’s, think belongs to one.

The party’s leader spoke.

You can also test party’s by replacing it with party is or party has.

The party’s ready.

→ The party is ready.

If that replacement works, party’s is a contraction.

But:

The party’s leader spoke.

You cannot replace it with party is leader. Here, the apostrophe shows possession.
