有朝一日
yoǔ zhāo yī rì · HSK 7
one day
🌅 有朝一日 = have (有) + morning (朝) + one (一) + day (日): there will be some one morning
有 — hand 𠂇 + moon/meat 月
Originally depicted a hand holding a piece of meat (月 here is the 'meat' radical, not moon), expressing the idea of possessing something. Over time the meaning broadened from 'to hold/possess' to the general sense of 'to have' or 'there is/exists'.
朝 — 十 + 日 + 十 + 月 (sun rising among grass, moon fading)
Originally a pictograph showing the sun (日) rising among grass or trees with the moon (月) still visible, depicting dawn. The core meaning 'morning' (zhāo) was extended to 'dynasty' or 'court audience' (cháo), since officials gathered before the ruler at daybreak.
一 — single horizontal stroke
一 is one of the simplest pictographs in Chinese, depicting a single horizontal line to represent the number one. It has retained essentially the same form since oracle bone script over 3,000 years ago. By extension it also means 'first,' 'whole,' or 'same.'
日 — pictograph of the sun
日 is a pictograph of the sun, originally drawn as a circle with a dot or stroke inside representing the sun's substance. Over time the round shape was squared off into the modern rectangular form. It means 'sun' and by extension 'day'.
