The kanji 緯緯 is a phono-semantic compound (形声文字). The left side is the radical 糸 (糸) "silk" or "thread," which gives an indication of the meaning. The right side is 韋 (い) that represents the phonetic component, suggesting the sound and also implicitly the idea of something that binds or connects, like threads in weaving. Thus, 緯緯 combines the concept of thread with a phonetic element, representing the horizontal threads in weaving. The character's formation reflects the importance of weaving in ancient times.
