逆立ち
さかだち · sakadachi · JLPT N1 · noun
handstand
逆 — 辶 walk + 屰 (inverted 大 person)
逆 combines the walking radical 辶 with 屰, a pictograph of an upside-down person. The original sense was 'to meet, go against the flow,' as if walking toward someone coming the opposite way. From this it extended to mean 'reverse, contrary, disobey.'
立 — person standing on ground (大 over 一)
Pictograph of a person standing with arms outstretched on the ground line below. The original oracle bone form clearly shows a frontal human figure planted on the earth. The core meaning 'to stand' extended to 'establish, set up, erect.'
