The kanji 級 is a 形声文字 (keisei moji), or a phono-semantic compound character. The left side is a component from 糸 (ito), meaning "thread" or "silk", and the right side is 丣 which indicates the sound "kyuu". Initially, the character was related to silk, with the 糸 component suggesting the precise grading or sorting of silk threads into different quality levels. Over time, the meaning extended to represent other types of "grades" or "levels."
