Parties or Partys: 7 Simple Spelling Rules

If you’re stuck on partys or parties you’re dealing with a common English spelling mistake. The correct plural form of party is parties. You don’t add just an s because the word ends in a consonant followed by y. Instead you change the y to i and add es.

This small spelling rule shows up in many everyday words. Once you understand it you’ll know why parties is correct and how the same pattern works with words such as cities babies stories and companies.

This guide explains the plural rule in simple terms. You’ll also see real examples learn when the rule changes and discover an easy way to remember the correct spelling.

Comparison Table

Word	Meaning	Example Sentence	When to Use It
Party	One gathering group or political organization.	We planned a party for Saturday.	Use it for one party.
Parties	More than one gathering group or political organization.	Several parties were held last month.	Use it for two or more parties.
Partys	Incorrect spelling.	This spelling is incorrect.	Do not use it.

Why The Spelling Changes

The confusion comes from a simple question. If the singular word is party why can’t you just add s and write partys?

English has a spelling rule for many nouns that end in y. When the letter before the y is a consonant you usually change the y to i and add es when making the plural. Since party ends in ty the letter before y is t. The t is a consonant so the spelling changes.

That gives us this pattern.

Party becomes parties.

The y changes to i and es is added. You don’t keep the original y.

The same pattern appears in many familiar words. A city becomes cities. A baby becomes babies. A story becomes stories. A company becomes companies.

Once you see several examples together the rule becomes much easier to remember.

The Rule For Words Ending In Y

The key is to look at the letter immediately before the final y. Don’t focus only on the y itself.

If a word ends in a consonant followed by y you normally change the y to i and add es.

For example:

• City becomes cities.
• Baby becomes babies.
• Family becomes families.
• Country becomes countries.
• Story becomes stories.
• Library becomes libraries.
• Activity becomes activities.
• Party becomes parties.

The spelling change happens because these words have a consonant before the y.

You can think of the rule as a quick two step process. First remove the final y. Then add ies.

For party that gives you this:

Party → part → parties.

The middle step is only there to show the spelling change. You aren’t turning the word into part. You’re replacing the final y with ies.

This rule is useful far beyond one word. It gives you a reliable way to spell many common plurals without having to memorize every word separately.

When You Keep The Y

There is an important difference to remember. Not every word ending in y changes to ies.

If a word ends in a vowel followed by y you usually keep the y and simply add s.

Look at these examples:

• Boy becomes boys.
• Toy becomes toys.
• Key becomes keys.
• Day becomes days.
• Journey becomes journeys.
• Monkey becomes monkeys.
• Holiday becomes holidays.

Why don’t these words change?

Look at the letter before the y.

In boy the letter before y is o. The letter o is a vowel. In toy the letter before y is o. In day the letter before y is a.

So the pattern is different.

Compare these two groups.

Consonant plus y

• Party becomes parties.
• City becomes cities.
• Baby becomes babies.
• Story becomes stories.

Vowel plus y

• Boy becomes boys.
• Toy becomes toys.
• Key becomes keys.
• Day becomes days.

That small check can save you from many spelling errors.

How To Tell Which Rule Applies

When you need to make a word ending in y plural take a quick look at the letter before the y.

If you see a consonant change y to ies.

If you see a vowel keep the y and add s.

For example consider the word family. The letter before y is l. Since l is a consonant the plural is families.

Now consider journey. The letter before y is e. Since e is a vowel the plural is journeys.

This is much easier than trying to remember a long list of exceptions. You simply inspect the final two letters and apply the right pattern.

Real Examples With Parties

The word parties can refer to many kinds of groups or events. It doesn’t only describe birthday celebrations.

Here are some natural examples.

• We went to two parties last weekend.
• The neighborhood hosts several parties during the summer.
• Her parents organized separate parties for the children.
• The hotel is available for private parties.
• Several political parties are represented in the election.
• The two parties reached an agreement after several meetings.
• Both parties signed the contract.
• The lawyers met with the parties involved in the case.

These examples show why context matters. The plural form can describe social events political groups or people involved in an agreement.

The Different Meanings Of Party

Understanding the meaning of the word also helps you understand why the plural form appears in so many places.

Party As A Social Event

The most familiar meaning is a social gathering where people meet to celebrate or spend time together.

You might have a birthday party a graduation party a dinner party or a holiday party.

For example:

• We had a small party after the graduation ceremony.
• The office held a party for the new employees.
• Three parties were scheduled at the venue this weekend.

Here parties simply means more than one social gathering.

Party As A Group In Politics

The word can also describe a political organization. In the United States you may hear people talk about political parties such as the Democratic Party or the Republican Party.

When discussing more than one political organization the plural form is parties.

For example:

• Several political parties competed in the election.
• The parties presented different plans to voters.
• Some voters are not strongly connected to either major party.

The meaning changes but the plural spelling stays the same.

Party As A Group In An Agreement

Legal and business writing uses party in another way. It can describe a person or group involved in a contract agreement case or other formal matter.

For example:

• Both parties signed the agreement.
• The parties agreed to meet again next month.
• Each party is responsible for its own costs.

Here the word has nothing to do with a celebration. It means the people or groups involved in a matter.

That makes parties a useful word with several meanings. The spelling remains the same in each case.

Why Partys Looks Tempting

The incorrect form can look reasonable because many English plurals are formed by adding s. We write book as books and car as cars. It makes sense to assume that party should become partys by following the same simple pattern.

The problem is that English has different plural spelling patterns. Words ending in consonant plus y follow a different rule. The final y changes to i before es is added.

This is also why the mistake can survive a quick visual check. Party and partys look similar enough that your eyes may not immediately catch the problem. The correct form parties looks different because the spelling change is more noticeable.

Once you learn the pattern you won’t need to rely on how the word looks. You’ll know exactly what to do.

A Simple Memory Trick

Think of the final y as something that needs to change when a consonant comes before it.

Say this to yourself:

Consonant before y means y changes to ies.

You can then test the word.

Party has t before y. T is a consonant. So y changes to i and es is added.

Party becomes parties.

Now try boy. Boy has o before y. O is a vowel. The y stays and you add s.

Boy becomes boys.

This quick comparison makes the rule easier to remember because you’re not memorizing one spelling. You’re learning a pattern that works across many words.

More Words That Follow The Same Pattern

The spelling change in party is part of a much larger group. Knowing these examples will make the rule feel natural.

City And Cities

A city is one place. Cities means more than one.

• New York is a busy city.
• Several cities are located along the coast.

Baby And Babies

A baby is one young child. Babies means more than one.

• The baby is sleeping.
• The hospital cares for newborn babies.

Story And Stories

A story is one account or tale. Stories means more than one.

• She told an interesting story.
• The book contains several short stories.

Company And Companies

A company is one business. Companies means more than one.

• The company hired five new workers.
• Several companies submitted proposals.

Country And Countries

A country is one nation. Countries means more than one.

• Canada is a country.
• Many countries have joined the agreement.

The spelling pattern remains consistent across all these examples. The letter before y determines what happens to the final y.

More Examples Of The Plural Rule

The spelling change from y to ies appears in many everyday nouns. Once you recognize the pattern you can apply it without stopping to think about every word.

Consider library. The word ends with ry and r is a consonant. So the plural becomes libraries.

• The town has one public library.
• The city has several public libraries.

The same thing happens with activity. The letter before y is t. Since t is a consonant the plural is activities.

• This activity is fun for children.
• The teacher planned several activities for the class.

You can also see the pattern in community.

• Our community has a new park.
• Local communities often organize events together.

Other examples include ability and abilities. You can also see responsibility become responsibilities and opportunity become opportunities.

The words may have different meanings but their plural spelling follows the same basic pattern.

Common Words That End In Consonant Plus Y

Learning a group of examples can help the rule become second nature. Here are some words you may use often.

Singular	Plural	Example
Party	Parties	Several parties attended the event.
City	Cities	The company operates in five cities.
Family	Families	Many families visit the park.
Baby	Babies	The clinic cares for newborn babies.
Story	Stories	She writes short stories.
Country	Countries	People from many countries attended.
Company	Companies	Several companies joined the project.
Library	Libraries	These libraries offer free programs.
Activity	Activities	The camp offers outdoor activities.
Community	Communities	Small communities can work together.
Factory	Factories	The company owns two factories.
Mystery	Mysteries	She enjoys reading mysteries.

Notice something useful here. The rule doesn’t depend on how long the word is or what it means. The key is simply the letter before the final y.

Common Words That Keep The Y

Now compare those words with nouns that have a vowel before the final y. These words don’t change y to i. They simply take s.

For example day becomes days. The letter before y is a. Since a is a vowel the y stays in place.

The same thing happens with boy and boys. The o before y is a vowel.

You can see the pattern in these examples.

Singular	Plural	Example
Boy	Boys	The boys played outside.
Toy	Toys	The children put away their toys.
Day	Days	We spent three days at the beach.
Key	Keys	I left my keys on the table.
Way	Ways	There are several ways to solve the problem.
Journey	Journeys	Their journeys took them across the country.
Holiday	Holidays	We spend most holidays with family.
Essay	Essays	The students submitted their essays.
Valley	Valleys	The road passes through several valleys.
Monkey	Monkeys	The zoo has several monkeys.

This gives you a useful side by side comparison.

Consonant plus y becomes ies.

Vowel plus y becomes ys.

That one distinction explains most plural spelling questions involving final y.

How The Rule Works With Party

The word party follows the consonant plus y pattern.

Look at the final two letters.

ty

The letter before y is t. T is a consonant. So the final y changes to i and es is added.

• Party becomes parties.
• The same process works with city.
• City becomes cities.
• It also works with family.
• Family becomes families.
• Now compare day.

The letter before y is a. A is a vowel. The y stays in place and s is added.

Day becomes days.

Once you make that quick check the spelling becomes much easier.

Singular And Plural Meaning

The difference between party and parties is not only about spelling. The form also tells the reader how many you mean.

Use the singular form when you’re talking about one.

• We have a party on Saturday.
• The party starts at seven.
• One party is scheduled for tonight.

Use the plural form when you’re talking about two or more.

• We have two parties on Saturday.
• Several parties are scheduled for the weekend.
• The parties will take place at different locations.

This distinction matters because English nouns often change form to show number. The singular form refers to one. The plural form normally refers to more than one.

When Party Is Used As A Political Term

The word has a second meaning that can cause confusion for learners. In politics party refers to an organized group that shares certain political ideas or goals.

For example you may hear someone say:

• She joined a political party.
• The party announced its new policy.
• Several parties are competing in the election.

When you refer to more than one political group the plural form is parties.

For example:

• Several parties are taking part in the election.
• The parties have different views on the issue.
• Two major parties received most of the votes.

The spelling rule doesn’t change because the meaning changes. Party still becomes parties.

When Party Refers To People In An Agreement

You may also see party in legal contracts and formal business writing. In this context it means a person group or organization involved in an agreement or dispute.

For example:

• Both parties signed the contract.
• Each party must follow the terms of the agreement.
• The parties agreed to settle the dispute.

Here parties does not mean social events. It means the people or groups involved.

This use appears often in phrases such as both parties interested parties involved parties and third parties.

The meaning depends on context. The spelling does not.

Common Mistakes With Parties

Some mistakes happen because writers apply the wrong plural rule. Others happen because they confuse related words.

Adding S To Party

The most obvious mistake is simply adding s.

Incorrect:

• We went to two partys last weekend.

Correct:

• We went to two parties last weekend.

The problem is the final y. Because a consonant comes before it the y must change before the plural ending is added.

Using Parties For One Event

Another mistake is using the plural form when only one event exists.

Incorrect:

• I’m going to a parties tonight.

Correct:

• I’m going to a party tonight.

The article a tells you that you mean one. The singular noun must follow it.

Using Party When You Mean More Than One

The opposite mistake can also happen.

Incorrect:

• We attended three party last month.

Correct:

• We attended three parties last month.

A number greater than one normally requires the plural noun.

Confusing Party With Parties In Formal Writing

Legal and political writing often uses these words in ways that can seem unfamiliar. For example both parties means two people or groups involved in an agreement. It does not mean two celebrations.

Context makes the meaning clear.

• Both parties signed the agreement.
• Both parties arrived at the birthday celebration.

The first sentence refers to people or groups in an agreement. The second refers to two groups at a social event.

Party As A Verb

Party can also work as a verb. It means to spend time enjoying yourself at a social event or celebration.

For example:

• We partied until midnight.
• They like to party on weekends.
• The students partied after graduation.

This creates another useful point about spelling. The plural noun parties and the verb forms partied and partying follow different spelling patterns.

Understanding the word’s role in a sentence helps you choose the right form.

Party As A Noun

• We planned a party for Friday.
• Several parties were held at the hotel.

Party As A Verb

• They party every weekend.
• They partied after the concert.

The spelling changes because the grammar changes. Parties is the plural noun form. Partied is the past tense of the verb. Partying is the present participle or gerund.

Party And Partied

The past tense of the verb follows a different rule from the plural noun.

When party becomes a past tense verb you change y to i and add ed.

Party becomes partied.

For example:

• We partied after the wedding.
• They partied late into the night.

Don’t confuse this with the plural noun.

Party becomes parties.

• We attended several parties.
• The hotel hosts private parties.

The difference is easy to see once you look at the ending.

Parties is a plural noun.

Partied is a past tense verb.

They both begin with the same spelling change but they have different endings and different jobs in a sentence.

Party And Partying

The form partying follows another common spelling rule. When a verb ends in y you usually keep the y when adding ing.

So:

Party becomes partying.

For example:

• They were partying at a friend’s house.
• We spent the evening partying with our friends.

This gives you three useful forms to remember.

• Party is the base form.
• Parties is the plural noun or third person singular verb form.
• Partied is the past tense.
• Partying is the ing form.

These forms may look similar but they aren’t interchangeable.

A Quick Test You Can Use

When you aren’t sure which form to use take a second to identify what the word is doing in the sentence.

• If you’re talking about one event or group use party.
• If you’re talking about more than one use parties.
• If you’re describing a past action use partied.
• If you’re describing an action in progress use partying.

For example:

• We planned a party.
• We planned three parties.
• We partied after dinner.
• We were partying when the rain started.

This simple test can help you avoid several different mistakes at once.

A Note About Family Words

The same plural spelling pattern appears in many words that end in consonant plus y. This includes words such as family country company and community.

For example:

• One family becomes two families.
• One country becomes several countries.
• One company becomes many companies.
• One community becomes several communities.

The rule remains the same. The y changes to i and es is added.

However some words that end in y are treated differently because they have a vowel before the y. That’s why day becomes days and boy becomes boys.

Checking the letter before y is the safest habit.

How To Remember The Spelling

A good memory trick is to think about the final two letters instead of the whole word.

For party you see ty. Since t is a consonant the y changes.

For toy you see oy. Since o is a vowel the y stays.

You can practice with a few pairs.

• Party and parties.
• City and cities.
• Baby and babies.
• Toy and toys.
• Boy and boys.
• Day and days.

Put the pairs side by side and the difference becomes much easier to spot.

Another useful trick is to say the rule in plain English. Consonant before y means change y to ies. Vowel before y means keep y and add s.

It isn’t a rule you need to recite every time you write. With practice your brain will start recognizing the pattern automatically.

Why This Rule Matters Beyond One Word

Learning this spelling pattern gives you a tool you can use across hundreds of sentences. Instead of memorizing isolated spellings you can make an informed choice based on the letters in the word.

That matters when you’re writing quickly. You won’t always have a dictionary or spell checker open. A basic understanding of plural rules lets you check your own work.

It also helps when you read. Once you recognize the pattern you’ll notice why words such as cities families and companies look different from boys toys and days.

English spelling has plenty of exceptions but many everyday words follow predictable patterns. Learning those patterns makes spelling feel less like guesswork and more like a skill you can control.

Other Plural Rules Worth Knowing

The spelling rule for words ending in consonant plus y is useful, but it isn’t the only plural rule in English. Once you understand how party changes to its plural form, it helps to know a few other patterns too.

Most regular nouns simply take s.

• Book becomes books.
• Car becomes cars.
• Table becomes tables.
• Phone becomes phones.
• Student becomes students.

Some nouns take es instead.

• Box becomes boxes.
• Bus becomes buses.
• Dish becomes dishes.
• Watch becomes watches.
• Class becomes classes.

Words ending in consonant plus y follow the pattern you’ve already learned. The y changes to i and es is added.

• Party becomes parties.
• City becomes cities.
• Story becomes stories.
• Family becomes families.

There are also irregular nouns that don’t follow these patterns at all. For example child becomes children and person can become people. Those forms need to be learned individually.

The good news is that the plural of party is completely regular. You don’t need to memorize it as an unusual exception.

What Happens When A Word Ends In Y

The final y rule can seem complicated at first. It becomes much simpler when you split words into two groups.

Consonant Before Y

When a noun ends in a consonant followed by y the y normally changes to i and es is added.

Here are some examples.

• Party becomes parties.
• Puppy becomes puppies.
• Cherry becomes cherries.
• Penny becomes pennies.
• Library becomes libraries.
• Country becomes countries.
• Diary becomes diaries.
• Enemy becomes enemies.

Look at the letter immediately before y. In each case it is a consonant.

This pattern is common in everyday English. Once you learn it you can apply it to new words instead of relying only on memory.

Vowel Before Y

When a noun ends in a vowel followed by y you normally keep the y and add s.

For example:

• Day becomes days.
• Boy becomes boys.
• Toy becomes toys.
• Key becomes keys.
• Donkey becomes donkeys.
• Journey becomes journeys.
• Essay becomes essays.

Here the letter before y is a vowel. That is the key difference.

Compare party with boy. The first has t before y. The second has o before y. That small difference changes the plural spelling.

What About Names And Proper Nouns

The same basic idea can appear with names and proper nouns but you should be careful with capitalization and meaning.

For example a family name ending in y may form its plural in a way that depends on the letters before the y and the style being used. In everyday writing it’s best to check the accepted form for a specific name rather than blindly applying a general rule.

For ordinary nouns such as party the rule is straightforward.

• One party.
• Two parties.
• Several parties.

You don’t need an apostrophe to make a regular noun plural.

Don’t Use An Apostrophe For The Plural

This is another mistake worth clearing up. Some writers add an apostrophe when they want to make a word plural.

For example they may write:

• Party’s.
• City’s.
• Company’s.

Those forms don’t mean simply more than one. The apostrophe usually shows possession or forms a contraction.

For a normal plural noun use parties without an apostrophe.

Compare these sentences.

• The parties ended late.
• The party’s decorations were beautiful.

In the first sentence parties means more than one party.

In the second sentence party’s means something belongs to one party. The apostrophe shows possession.

You can also see this difference with other words.

• The cities are growing.
• The city’s population is growing.

The first sentence talks about more than one city. The second talks about the population belonging to one city.

This distinction is especially useful when proofreading because apostrophe mistakes can change the meaning of a sentence.

Parties As A Possessive Form

The plural form can also become possessive. That’s when the punctuation gets slightly different.

If you have more than one party and something belongs to all of them you usually place the apostrophe after the plural ending.

For example:

• The parties’ agreement was signed yesterday.
• The parties’ lawyers met in the afternoon.

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

If you’re talking about something belonging to one party you use party’s.

• The party’s location was changed.
• The party’s organizer called everyone.

The difference is small on the page but important in meaning.

• Party’s means belonging to one party.
• Parties’ means belonging to more than one party.
• Parties simply means more than one party.

Once you understand that difference the punctuation becomes much easier.

How The Word Appears In Different Types Of Writing

You’ll see this plural noun in many forms of American English. The context can change but the spelling remains the same.

Casual Writing

Friends might talk about several social events.

• We went to two parties last month.
• Are there any parties this weekend.

Business Writing

A contract may refer to the people or organizations involved in an agreement.

• Both parties must sign the document.
• The parties agreed to the new terms.

News Writing

A news article may discuss political organizations.

• Several parties are competing for seats.
• The parties released their statements on Tuesday.

Academic Writing

A student may use the word when discussing groups or historical events.

• The two parties reached an agreement.
• Different political parties supported the proposal.

This flexibility makes the word useful in many settings. You don’t need a different spelling for each meaning.

Why The Plural Sounds Different

There is also a small pronunciation detail that can help you recognize the plural when speaking.

The singular form has one syllable.

Party.

The plural has two syllables.

Parties.

The ending sounds like the final part of words such as cities and babies.

This matters because spoken English gives you another clue that the word has changed from singular to plural. You won’t hear the exact spelling but you’ll hear the additional syllable.

For example:

• One party.
• Two parties.

That difference is easy to hear when the words are spoken naturally.

Can Party Be A Countable Noun

Yes. When party means a social event or a particular group it is normally a countable noun.

That means you can talk about one party two parties or several parties.

You can also use words such as:

• A party.
• One party.
• Two parties.
• Several parties.
• Many parties.
• Few parties.

For example:

• We planned a party for Saturday.
• We planned two parties for the same weekend.
• Several parties were held at the hotel.

This is another reason the singular and plural forms matter. The word changes depending on the number you’re talking about.

Party In Common Expressions

English has many phrases that use this word. Knowing them can make the plural form easier to recognize.

Birthday Party

A birthday party is a celebration for someone’s birthday.

• We’re having a birthday party for my sister.

Dinner Party

A dinner party is a meal where people are invited to eat together.

• They hosted a dinner party for their neighbors.

Holiday Party

A holiday party is a social gathering connected with a holiday.

• The office is having a holiday party next week.

Political Party

A political party is an organized group with shared political goals.

• He joined a political party after college.

Third Party

A third party is an additional person or group involved in a matter.

• The contract requires approval from a third party.

These expressions show how much the meaning can change based on context. The spelling rule stays exactly the same.

A Few Sentences To Test Yourself

Try reading these sentences and decide why the noun is singular or plural.

We planned a party for Friday.

Only one event is being discussed so the singular form works.

We planned three parties for the summer.

The number three tells you that the plural form is needed.

Both parties signed the agreement.

Here the word refers to two groups involved in an agreement.

Several political parties joined the debate.

The sentence discusses more than one political organization.

The party’s music was too loud.

The apostrophe shows possession by one party.

The parties’ lawyers met before the hearing.

The apostrophe comes after the plural form because the lawyers belong to more than one party.

These examples cover several forms that look similar but serve different purposes.

A Simple Proofreading Trick

When you’re checking your writing search for words that end in y. Then look at the letter immediately before the y.

If it is a consonant ask yourself if the plural should end in ies.

If it is a vowel the plural will usually keep the y and add s.

For example:

• Party. T comes before y. Use parties.
• City. T comes before y. Use cities.
• Boy. O comes before y. Use boys.
• Key. E comes before y. Use keys.

This takes only a second once you’re used to it. It can also help you catch mistakes that spell check misses.

What Teachers Usually Expect

In school writing teachers expect standard English spelling. That means the plural form should follow the normal spelling rule.

A sentence such as The students attended three parties is correct.

A sentence such as The students attended three partys contains a spelling error.

This may seem like a small detail but spelling matters in essays reports applications and other formal work. A correct plural ending makes the sentence look polished and shows that you understand the basic structure of the word.

The same principle applies to professional writing. An email doesn’t need fancy language to sound polished. Correct spelling and clear sentences do much of the work.

What Spell Check Can And Cannot Do

A spell checker can be useful when you’re unsure about a spelling. If you type the incorrect form it will often suggest the correct one.

Still you shouldn’t depend on spell check for every decision. It may not catch every error and it cannot always understand what you mean.

For example party and parties are both correctly spelled words. A spell checker won’t know which one you intended if the wrong form fits the sentence grammatically.

Consider this sentence:

• We attended three party last weekend.

The problem isn’t that party is misspelled. The problem is that the sentence needs a plural noun after three.

A good proofreading habit combines spelling knowledge with sentence awareness. Ask what the sentence means and how many things you’re talking about.

The Fastest Way To Remember It

If you want one rule to remember take this one with you.

Consonant plus y changes to ies.

Then test the word.

Party → parties.

T comes before y so the y changes.

For comparison:

Boy → boys.

O comes before y so the y stays.

That’s the whole idea. You don’t need a complicated spelling formula.

A few minutes of practice with similar words can make the pattern stick. Write party parties beside boy boys and city cities. The contrast makes the rule easy to see.

When The Word Appears In Search Queries

People often type spelling questions exactly as they sound in their heads. They may search for partys or parties because they aren’t sure if the plural needs an s or an ies ending.

They may also search for questions such as:

• Is parties the plural of party.
• How do you spell the plural of party.
• Is partys a word.
• Why does party change to parties.
• What is the plural form of party.
• Do you change y to ies in party.

All of these questions have the same basic answer. The standard plural is parties.

The reason is the spelling rule for nouns ending in consonant plus y. Once that rule is clear the spelling stops being something you have to guess.

A Final Practice Exercise

Try filling in the missing forms before checking the answers.

• One party. Two ______.
• One city. Two ______.
• One baby. Two ______.
• One toy. Two ______.
• One day. Two ______.
• One family. Two ______.

The answers are:

Parties. Cities. Babies. Toys. Days. Families.

Look at the letter before y in each singular noun. You’ll see why some words change to ies while others keep the y.

That small check is one of the most useful spelling habits you can build. It turns a confusing choice into a simple decision based on the letters in front of you.

Conclusion

If you came here wondering about partys or parties the answer is simple. Parties is the correct plural spelling. The form partys is a spelling mistake and shouldn’t be used in standard English.

The reason is the plural rule for nouns ending in consonant plus y. When the letter before y is a consonant change y to i and add es. Since t comes before y in party the correct plural is parties.

The same pattern appears in many familiar words such as cities babies stories families and companies. But don’t apply the rule to every word ending in y. When a vowel comes before y the y usually stays in place. That’s why boy becomes boys and day becomes days.

So the next time you pause over partys or parties check the letter before the final y. T is a consonant so the y changes. Write parties and move on with confidence.
