同等
tóngděng · HSK 7
of same rank/status
⚖️ 同 same + 等 rank = same rank, on equal footing
同 means same, 等 means rank or grade (as in 等级, levels). Glued together they mean two things hold the same rank or status — coequal, on an equal footing.
同 — 冂 enclosure + 一 + 口 mouth
Originally depicted multiple mouths gathered under one cover or enclosure, suggesting people speaking together in agreement. From this image of voices joining, it came to mean 'same,' 'together,' or 'alike.' The shared cover symbolizes unity.
等 — bamboo radical 竹 + temple 寺
Originally referred to bamboo slips of equal length used for record-keeping, with 竹 (bamboo) as the semantic component and 寺 suggesting the phonetic. From 'equal-length slips' the meaning extended to 'rank, class,' then 'equal,' and later to 'wait' (to be of equal status in line).
