Origin

The character combines the radical for "going" or "path" (行) on both sides, framing the character 重, which serves as a sound hint for the pronunciation. The doubling of the "path" radical suggests movement or action along a road, while the overall idea of collision and impact comes from the sense of forceful movement — things that clash when they move toward each other on the same path. The sound component 重 helps indicate how the character is pronounced in Chinese and Japanese, even though its meaning (heavy) is separate from the character's core sense of impact and thrust.
