| Word | Function | Meaning |
| Party | Singular noun | One party |

| Party’s | Singular possessive | Belonging to one party |
| Parties’ | Plural possessive | Belonging to multiple parties |
Understanding this distinction is essential for correct grammar and punctuation.

Parties is the plural form of the noun party.
It can refer to:
- Multiple celebrations
- Several groups
- More than one political party
- Multiple individuals involved in a legal agreement

In all these examples, parties simply means more than one party.

What Is the Plural Form of Party?
The plural of party is parties.
Many learners mistakenly write partys, but that spelling is incorrect.

✅ Party → Parties

Why Party Changes to Parties
English spelling follows a common rule.
When a noun ends with:
Consonant + Y
change the y to ies when forming the plural.
Examples
| Singular | Plural |
| Party | Parties |
| Baby | Babies |
| City | Cities |
| Lady | Ladies |
| Story | Stories |
Since party ends in ty, the correct plural becomes parties.
The Consonant + Y Rule
The rule is straightforward:
If a word ends in a consonant + y:
Remove the y and add ies.
Examples
- Party → Parties
- Country → Countries
- Family → Families
- Library → Libraries
This is why partys is never correct.
When to Use Parties
Use parties whenever you’re referring to more than one party.
