紛失（ふんしつ、funshitsu）
- loss

The Japanese word 紛失 （ふんしつ, *funshitsu*) means "loss" or "to lose something." It describes the situation where something that was once possessed is no longer found or cannot be located. This usually implies that the item is missing and the owner doesn't know where it is, whether it's been misplaced, stolen, or otherwise gone. The key element is the inability to find or retrieve the item. It is a more formal word.

It's often used when reporting the loss to authorities, writing a formal report, or in more serious conversations. You can use it when talking about inanimate objects, documents, or personal belongings. It's less commonly used for the loss of something intangible, like a skill or feeling.
