Partys or Parties: Which Spelling Is Correct?

If you’re writing about several celebrations, political groups, social gatherings, or organized groups, you may wonder whether the plural of party is partys or parties. This is a common spelling question because many English nouns simply add -s to form their plurals.

The correct plural spelling is parties. Partys is incorrect when you mean more than one party. The spelling changes from party to parties because the word ends in a consonant followed by y.

Quick answer: The correct spelling is parties, not partys. For example, “We attended two parties last weekend” is correct In this guide, you’ll learn why parties is correct, how to use it in sentences, when to use party’s or parties’, and how to avoid common mistakes.

Partys or Parties: What’s the Difference?

The difference is simple:

Word	Correct?	Meaning	Example
party	Yes	One party	We planned a party.
parties	Yes	More than one party	We attended several parties.
partys	No	Incorrect plural spelling	❌ We attended three partys.
party’s	Yes	Belonging to one party or “party is”	The party’s location is nearby.
parties’	Yes	Belonging to multiple parties	The parties’ schedules were different.

The main point is that parties is the standard plural form of party.

Why Is “Parties” the Correct Plural?

The spelling rule explains the change.

When a noun ends in a consonant + y, the y usually changes to i before adding -es.

So:

• party → parties
• city → cities
• baby → babies
• story → stories
• country → countries
• family → families

The word party follows this standard English pluralization rule.

Why Isn’t It “Partys”?

Simply adding -s would produce partys, but that isn’t the standard English plural spelling. The final y changes to ie, giving us parties.

Party + -es → parties

This spelling represents the plural form correctly in standard American English.

How Do You Spell the Plural of “Party”?

The plural of party is spelled parties.

The spelling changes as follows:

party → parties

For example:

• We are having a party tonight.
• We are having several parties this month.

The same pattern applies to many other words ending in consonant + y.

When Do You Use “Party”?

Use party when you’re talking about one party.

Examples:

• We’re hosting a birthday party.
• The party starts at 7 p.m.
• She invited me to her graduation party.
• The office is planning a holiday party.
• They had a small dinner party.

Because party refers to one event or group in these examples, the singular form is appropriate.

Use parties when you’re talking about two or more parties.

Examples:

• We attended two birthday parties last month.
• Several parties were held at the venue.

• Both parties agreed to the arrangement.

The word parties can refer to different kinds of groups or events, depending on the context.

Here, parties means multiple social events.

Parties as Groups of People

Party can also mean a group of people involved in an activity or agreement.

Here, parties refers to two groups involved in the agreement, not two celebrations.

Parties in Politics

Party’s vs Parties’: Don’t Confuse the Possessive Forms

One reason people search for partys or. parties is that English has several forms of the word that look similar.

The three most important forms are:

• party — singular
• parties — plural
• party’s — singular possessive or contraction
• parties’ — plural possessive

What Does “Party’s” Mean?

Party’s can show possession by one party.

For example:

The party’s location was changed.

This means the location belongs to or is associated with one party. Party’s can also be a contraction of party is in some contexts, although this use is less common.

For example:

The party’s starting soon.

Here, party’s means party is.

What Does “Parties'” Mean?

Parties’ is the possessive form of the plural parties.

For example:

The parties’ responsibilities were clearly defined.

This means the responsibilities belong to multiple parties.

Compare:

• The party’s plans = plans of one party
• The parties’ plans = plans of multiple parties

The apostrophe comes after the s in parties’ because parties is already plural.

Partys, Parties, Party’s, and Parties’ Compared

These forms are easy to mix up, so here’s a quick reference:

Form	Use	Example
party	Singular	The party begins at 8.
parties	Plural	We attended several parties.
party’s	Singular possessive	The party’s theme was blue.
parties’	Plural possessive	The parties’ schedules conflicted.
partys	Incorrect	❌ We attended two partys.

If you’re simply making party plural, don’t add an apostrophe. Write parties.

Why Do Words Ending in “Y” Change to “IES”?

English has a common spelling pattern for nouns ending in consonant + y.

The y changes to i, and -es is added.

Examples include:

• party → parties
• city → cities
• company → companies
• library → libraries
• country → countries
• enemy → enemies
• university → universities

This is why parties, rather than partys, is the correct spelling.

What About Words Ending in a Vowel + Y?

The rule is different when a word ends in a vowel + y. In those cases, the y usually stays and you simply add -s.

Examples:

• boy → boys
• toy → toys
• day → days
• key → keys
• journey → journeys

Compare:

• party → parties
• boy → boys

The letter before the y determines which plural pattern is used.

Common Mistakes With “Parties”

Mistake 1: Writing “Partys”

This is the most common spelling error.

Incorrect:

We went to several partys.

Correct:

We went to several parties.

Mistake 2: Using “Party’s” as the Plural

An apostrophe does not normally make a noun plural.

Incorrect:

We attended three party’s.

Correct:

We attended three parties.

Party’s is possessive or can be a contraction, not the ordinary plural.

Mistake 3: Writing “Parties” When You Mean One Party

Because parties is plural, it shouldn’t be used with a singular meaning.

Incorrect:

The parties starts at 6 p.m.

Correct:

The party starts at 6 p.m.

Mistake 4: Confusing “Parties'” With “Parties”

These forms have different functions.

• parties = more than one party
• parties’ = something belonging to multiple parties

Compare:

Several parties attended the meeting.

The parties’ representatives attended the meeting.

The apostrophe changes the grammatical role of the word.

Is “Partys” Ever Correct?

Partys is not the standard plural spelling of party. If you’re referring to multiple parties, use parties. There may be unusual contexts in which a sequence of letters happens to contain “partys,” such as a username, brand name, filename, or other intentionally created name. But in standard English writing, partys should not be used as the plural of party.

How to Remember “Party → Parties”

A simple memory trick is:

Consonant + Y → change Y to I and add ES.

So:

party → parties

You can remember it with a few familiar examples:

• city → cities
• baby → babies
• story → stories
• party → parties

Think of party as following the same spelling pattern as city and story.

Quick Tips for Remembering the Correct Spelling

Keep these rules in mind:

• One: party
• More than one: parties
• One party’s possession: party’s
• Multiple parties’ possession: parties’
• Never use “partys” as the standard plural.
• For consonant + y nouns, remember the y → ies pattern.

A useful mental shortcut is:

party + ies = parties

If you’re talking about multiple celebrations, groups, or organizations, parties is the form you want.

Conclusion

The correct spelling is parties, not partys, when you’re referring to more than one party. The change happens because party ends in a consonant followed by y, so the y changes to i and -es is added: party → parties.

It’s also important to distinguish parties from party’s and parties’. Party’s shows possession by one party, while parties’ shows possession by multiple parties. These apostrophe forms have different grammatical purposes and shouldn’t be used as ordinary plurals.

Once you remember the consonant + y → ies rule, the partys or. parties question becomes easy. Whether you’re writing about social gatherings, business agreements, or political organizations, use parties for the standard plural form.
