middle level (in a hierarchy)
📊 中级 = 中 (middle) + 级 (level/grade)

中 — vertical stroke 丨 through enclosure 口
Pictograph of a banner or pole piercing the center of a target or territory, depicting the idea of 'middle' or 'center'. The horizontal frame represents boundaries, and the vertical line marks the central axis. The meaning extended from spatial center to 'middle, central, China' (中国, the Middle Kingdom).
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.'
