左边
zuǒ bian · HSK 1
left
👈 左 = left hand + work (zuǒ); 边 = side/edge (biān)
左边 decomposes as 左 (left) + 边 (side). 左 originally depicted a left hand holding a tool; 边 means side or edge. Together: the left side.
左 — hand 𠂇 + work 工
Originally a pictograph of the left hand, later combined with 工 ('work') to specify the meaning 'left' and distinguish it from 右 ('right', hand + mouth). The hand component 𠂇 depicts fingers and a wrist, while 工 was added as a semantic clarifier referring to assisting work.
边 — 辶 (walk) + 臱 (phonetic)
边 is the simplified form of 邊. It combines the walking radical 辶 with the phonetic component 臱, suggesting a place reached by walking — the edge or border of a territory. The meaning extended from 'frontier' to 'side' or 'edge' in general.
