belongings
The personal things you own and carry with you.
Your belongings are the things that belong to you: your possessions, your stuff, the objects you own. When you pack for a trip, you gather your belongings into a suitcase. When the fire alarm rings at school, you might be told to leave your belongings behind and exit quickly.
The word usually refers to personal items you can carry or move, like clothes, books, toys, or a backpack, rather than big things like houses or cars. After gym class, you collect your belongings from your locker. When staying at a friend's house, you keep track of your belongings so you don't accidentally leave anything behind.
People often say “personal belongings” to emphasize that these items are privately owned and meaningful to someone. A lost-and-found box holds the belongings that students have misplaced. Your belongings might not be valuable to anyone else, but they're yours, and that matters.
