Details

The keyword for 重 is heavy. This kanji conveys the concept of weight, heaviness, and gravity, both in a physical and metaphorical sense. It can describe something that is literally heavy in mass, but it also extends to meanings of importance, seriousness, and significance, as something "weighty" carries great consequence. Additionally, it can express the idea of layering or piling up, as multiple layers stacked together naturally become heavier.
