Party’s or Parties: What Is the Difference?

Party’s means something belongs to one party. Parties means more than one party.

Last week, Mia made an invite for her brother. She wrote, “Join us for the parties start time.” Then she stopped. Was it party’s or parties? She did not know.

A party is a fun event. It can also be a side in a deal or a vote. Party’s has a small mark called an apostrophe (‘). It shows that something belongs to one party. It can also mean “party is,” as in “the party’s at six.” Parties has no mark. It means two or more parties.

People search for party’s or parties because the words sound the same. They look the same, too. One small mark changes the meaning. This guide makes it easy. You will learn how to pick party’s or parties every time.

The Origin of Party’s and Parties

“Party” comes from the old French word partie. It meant a part or a side. French took it from a Latin word that means “to divide.”

English used “party” in the 1200s and 1300s. It meant a side in a fight or a deal. By the 1700s, it also meant a fun group event.

To make “many,” English changes the “y” to “ies.” That gives us parties.

British vs American English

• Groups: The US says, “The party is split.” The UK may say, “The party are split.”
• Event names: The UK says “hen party.” The US says “bachelorette party.”
