公表
こうひょう · kouhyou · JLPT N2 · noun
announcement
📢 公 (public) + 表 (show) = show it to the public: official announcement
公 means public or official, and 表 means to show or display. Making something public through an official channel is 公表. Compare 発表, which is a broader 'announcement' that need not be official.
公 — eight 八 + private 厶
Originally an ideograph showing 八 (to divide) over 厶 (private/self), depicting the act of splitting away from selfish interest. The combination came to mean 'public' or 'fair,' the opposite of private. It later extended to senses like 'duke,' 'lord,' and 'grandfather.'
表 — fur 毛 on top + garment 衣 below
Originally depicted an outer fur garment, with 毛 (fur) above 衣 (clothing), showing the hairy outside of a coat. From 'outer garment' it extended to mean 'outside, surface,' then 'to show, express, display,' and later 'table, chart' as something laid out on the surface.
