📊 等级 = wait/rank (等) + level/step (级)
等 means rank or class (also 'to wait'), and 级 means level or grade (the 纟 silk radical hints at threading steps together). Together 等级 names a graded scale — a rank-by-level system.
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).
级 — silk radical 纟 + 及 jí (phonetic)
级 is a semantic-phonetic compound. The silk radical 纟 originally referred to threads or the steps/ranks of silk cords used to mark official grades. The right side 及 (jí) supplies the sound. Over time the meaning shifted from 'cord-marked rank' to general 'level, grade, class.'
