noun
you all; all of them; gentlemen
Formal, somewhat literary term used to address or refer to a group of people, often in speeches or written announcements. Can be translated as 'ladies and gentlemen' in appropriate contexts, though it is not gender-specific in Japanese.
ご来場の諸氏に感謝申し上げます。
I would like to express my gratitude to all of you who have come.
関係諸氏のご尽力により、計画は成功した。
Thanks to the efforts of all those involved, the plan was a success.
Compound of 諸 (しょ, 'various') and 氏 (し, 'Mr./Ms.'), literally meaning 'various gentlemen/ladies'. The exact historical derivation is uncertain, but it has been used as a formal plural address term.
