至关重要
zhì guān zhòng yào · HSK 7
extremely important
🔑 重要 = heavy(重) + want(要) = important; 至关 = reaching the crucial gate
Four parts: 至 reach + 关 gate/pass + 重 heavy + 要 want. Something so weighty-and-wanted it reaches the critical gate — i.e. absolutely vital. 重要 alone already means important; 至关 cranks it to the max.
至 — arrow 矢 inverted + ground 一
至 is a pictograph showing an arrow (矢) landing point-down on the ground (一), depicting the moment it reaches its target. The original meaning was 'to arrive' or 'to reach,' which extended to 'utmost' or 'extreme' — the point beyond which one cannot go further.
关 — door 门 + simplified 关 inside
关 is the simplified form of 關. The traditional character showed a gate (門) with a bolt or crossbar inside, depicting a barred door — hence 'to close' or 'shut'. Meaning later extended to 'pass' (a guarded gate), 'barrier', and figuratively 'concern' or 'connection'.
重 — person 人 + east 東 (phonetic)
Originally depicted a person carrying a heavy bundle on their back, suggesting weight and burden. The 東-like element served as a phonetic component. Over time the character split into two readings: zhòng meaning 'heavy' and chóng meaning 'repeat/again'.
要 — west 覀 (top) + woman 女 (bottom)
Originally a pictograph of a woman with hands on her waist, meaning 'waist' (the original form of 腰). The top 覀 is a stylized depiction of the waist area, not the character for 'west'. Over time it was borrowed for the meaning 'to want, important', so 腰 (with 月 flesh radical) was created for the original 'waist' sense.
