上去
shàng qù · HSK 3
to go up
⬆️ 上去 = 上 (up) + 去 (go)
上 means up/above and 去 means to go, so 上去 literally stacks them as go up. Used for movement upward away from the speaker, like climbing stairs or going up to a higher floor.
上 — horizontal line above a baseline
上 is an indicative character (指事): a short stroke placed above a longer reference line shows the concept of 'above' or 'up'. The earliest oracle-bone forms used two horizontal lines for this; the modern shape added a vertical stroke for clarity. The core meaning of 'upper, above, to ascend' has stayed stable for millennia.
去 — 土 earth on top + 厶 (originally 凵, a vessel/container) below
Originally a pictograph showing a person (大) departing from an enclosed area or vessel, suggesting leaving or going away. Over time the top simplified to 土 and the bottom to 厶. The core meaning 'to go, to leave, to depart' has remained stable since ancient Chinese.
