Based on reliable sources, if the user's native language is Vietnamese, there is a strong correspondence between Japanese kanji and Vietnamese. The kanji 質 corresponds to the Sino-Vietnamese word 質 (chất). This indicates that it shares the same origin and reflects a significant shared historical and cultural influence.

The kanji 質 is a 形声文字 (keisei moji), which means a phonetic-semantic compound character. The left side is a radical called 貝 (kai) which means "shell," which represents value, wealth, or something precious, and the right side is 斤 (kin), which is a "weight" measure. The combination of shell and weight means something of value. So, it means "to measure the quality" or "to assess something's value." This association led to the meanings of quality, substance, and the idea of offering something of value (like a pledge) as security.
