A possessive noun shows ownership or a relationship.
Consider these examples:
| Singular Noun | Possessive Form |
| Teacher | Teacher’s |
| Company | Company’s |
| Student | Student’s |
| Party | Party’s |
The apostrophe and the letter s tell readers that something belongs to someone or something.

It means there is more than one party.

Why Does Party Become Parties?
Many English learners wonder why the word changes from party to parties instead of partys.
The answer lies in an important spelling rule.
The Rule
When a noun ends in:
Consonant + Y
Remove the y and add ies.
Examples
| Singular | Plural |
| Party | Parties |
| City | Cities |
| Family | Families |
| Country | Countries |
| Baby | Babies |
Because the letter t is a consonant, party becomes parties.
The Exception to the Rule
When a word ends in:
Vowel + Y
You simply add s.
Examples
| Singular | Plural |
| Boy | Boys |
| Toy | Toys |
| Key | Keys |
| Day | Days |
This rule helps explain why we write:
- Parties
- Partys
Why Does Party’s Have an Apostrophe?
An apostrophe usually serves one of two purposes:
- To show ownership.
- To create contractions.
In party’s, the apostrophe shows ownership.
Example
The party’s decorations looked beautiful.
The decorations belonged to one party.
Without the apostrophe, the sentence changes entirely.
