The kanji 質 is a 形声文字 (keisei moji), a phono-semantic compound. The left side is a radical called 斤 (kin) - "axe," which originally meant "weight" or "balance." The right side is 斦 (shitsu), which is phonetically associated with the sound of the kanji. Together, they combine to suggest the idea of weighing something to determine its quality or value, thus the meanings "quality," "nature," or "substance" developed.
