大臣

1. Origins, structure, and basic meaning

• Structure: 大臣 is read だいじん and refers to a minister or senior official responsible for an area of government.
• Basic usage: It can describe a minister serving a king in a story or one speaking at a press conference.

2. Common pitfalls and similar expressions

• Office and portfolio
  • 大臣 alone does not identify the ministry or portfolio. That information comes from the full title or context.
• Minister and prime minister
  • 総理大臣 is the specific office of prime minister. Do not translate every ordinary use of 大臣 as prime minister.
