国庫

1. Origins, structure, and basic meaning

• Structure: 国庫 (こっこ) is a noun for the state-managed pool into and out of which public funds move.
• Basic usage: 国庫に納められる marks the destination into which a fine is paid, while 国庫から支出される marks the source from which expenses are disbursed.

2. Common pitfalls and similar expressions

• Inbound に and outbound から
  • 国庫に and 国庫から point in opposite directions of fund movement. Here 国庫 is the state treasury as a fiscal destination and source, not a physical storehouse.
