The word 柔软 is formed by combining two independent characters, each carrying a core meaning of suppleness, into a single, reinforced concept. The first character, 柔, conveys a sense of pliant gentleness, like a flexible willow branch, while the second, 软, directly denotes physical softness or lack of hardness. Placed together, they create a harmonious, parallel structure where each element mirrors and intensifies the other, painting a complete sensory picture of something that is both gentle to the touch and yielding in nature.
