私有

1. Origins, structure, and basic meaning

• Structure: 私有 (reading しゆう) is a noun and suru-verb for ownership of land or property by a private person or entity rather than the state or community.
• Basic usage: It identifies private property in 私有地 and private ownership as a system in 土地の私有.

2. Common pitfalls and similar expressions

• Ownership versus use
  • 私有 focuses on ownership, not merely on temporary or personal use of something.
• Compound and noun use
  • In 私有地 it qualifies the land; in 私有を認める, the concept of private ownership is the object.
