有料

1. Origins, structure, and basic meaning

• Structure: 有料(ゆうりょう) means that a fee is charged.
• Basic usage: It is used in information about facilities such as parking lots or exhibition rooms that charge for use.

2. Common pitfalls and similar expressions

• A fee applies versus payment completed
  • 有料です means a fee must be paid, not that payment has already been made. The English word paid has the sense of fee-based in this context.
• The scope of a fee
  • 展示室の一部は有料だが庭園は無料で入れる contrasts a fee for part of the exhibition rooms with free admission to the garden.
