正
zhèng · HSK 1
precisely
🎯 一 (one) + 止 (stop) = stop right on the one — exactly on target
正 combines 一 'one' over 止 'foot/stop': the foot halts precisely on the line. Hence 'exactly, precisely, punctually' — landing right on the mark, not a step over or under.
正 — one 一 + stop 止
Originally an ideograph showing a foot (止) advancing toward a target line (一), meaning 'to march straight toward' a city or goal. From this came the senses 'upright,' 'correct,' and 'proper.' The military sense survives in 征 (to campaign), which took over the original 'march' meaning.
