Safekeeping means protecting something valuable by storing it in a secure place where it won't be lost, stolen, or damaged. When you put your birthday money in your parents' wallet for safekeeping, you're trusting them to keep it safe until you need it. Museums hold ancient artifacts in safekeeping for future generations, and banks offer safekeeping for important documents like birth certificates or property deeds.

The word suggests both security and temporary care. You might give your house key to a neighbor for safekeeping while you're on vacation, or a teacher might hold a student's phone in safekeeping during a test. The person providing safekeeping takes responsibility for protecting something that belongs to someone else, like a trusted friend watching your backpack while you use the restroom at a crowded airport.

Notice that safekeeping implies the item will eventually be returned or remain available to its owner. It's different from giving something away permanently. When something is in your safekeeping, you're its guardian, not its owner. Libraries practice safekeeping with borrowed books, and parents practice safekeeping with childhood treasures their kids will want someday.
