諸君

1. Origins, structure, and basic meaning

• Structure: 諸君 (しょくん) is a form of address for an audience, translated here as gentlemen or everyone.
• Basic usage: 諸君、よく聞きなさい addresses the listeners directly; 聴衆を諸君と呼ぶ quotes the label used for them.

2. Common pitfalls and similar expressions

• Direct address versus quotation with と呼ぶ
  • Before the comma, 諸君 is vocative; in 諸君と呼ぶ, と marks the wording of the address. The source contexts present an old-fashioned speech style.
