保存

1. Origins, structure, and basic meaning

• Structure: Written 保存 and read ほぞん, it means keeping something so it does not spoil, disappear, or become lost.
• Basic usage: It covers refrigerating leftover food and saving photographs on another device.

2. Common pitfalls and similar expressions

• Physical preservation versus digital storage
  • With food it protects condition; with data it prevents information loss, so the method depends on the object.
