Last week, I was writing a simple sentence: “There are many birthday party’s this month.”
Something felt off. I paused, re-read it, and realized, I had made a mistake I’ve seen everywhere.
If you’ve ever been confused between parties or party’s, trust me, I’ve been there too. It’s one of those small grammar issues that can quietly ruin otherwise perfect writing.
People search parties or party’s because both look right at first glance. But they serve completely different purposes.
In this blog, I’ll break it down in the simplest way possible, so you can understand the difference, avoid common mistakes, and use each form confidently in real life.
Quick Answer
- ✔️ Parties = plural (more than one party)
- ✔️ Party’s = possessive (something belongs to one party)
Examples:
- ✔️ There are many parties this weekend.
- ✔️ The party’s theme is blue.
- ❌ There are many party’s this weekend.
👉 If you’re choosing between parties or party’s, remember:
No apostrophe for plural. Apostrophe shows ownership.
