The Chinese character 滑 (huá) has a fascinating origin that connects to both the visual and tactile sense of slipperiness. Let’s break down its components:

• 水 (shuǐ): This radical clearly represents water. This is key because water is often associated with slipperiness, think of wet surfaces or smooth flowing movement.
• 骨 (gǔ): This component represents bone. While seemingly unrelated to “slippery,” its ancient form might have depicted something smooth and hard like a bone or a polished surface. It also provides the phonetic element to the character.

Combining these elements, the original meaning of 滑 likely conveyed:

• Smoothness like water: The “water” radical combined with the smooth and hard imagery of “bone” could depict a surface so smooth that it’s like water flowing over it, creating a slippery effect.
• Effortless movement: The character might have also evoked the image of something gliding effortlessly over a surface, similar to how water flows smoothly.

Therefore, 滑 captured the essence of slipperiness through the visual imagery of water and the tactile sensation of smoothness.

Over time, the meaning expanded to include:

• Slippery surfaces: This remains the core meaning, describing surfaces like wet floors, ice, or oily roads.
• Smooth and glossy textures: 滑 can describe things like smooth skin, polished stones, or silky fabric.
• Cunning or sly: This metaphorical meaning likely arose from the idea of someone being “slippery” in their dealings, difficult to grasp or pin down.
