光滑

• Pinyin: guāng huá
• Hanzi breakdown: 光 = 火 + 人 (brightness, polish); 滑 = 氵+ 骨 (water + bone — slippery surface)

Meaning

Smooth; sleek; slippery. Describes a surface that is even, polished, and without roughness or friction.

Describes textures that are pleasant (polished marble, soft skin) or hazardous (icy road, wet floor). Commonly appears in product descriptions, safety warnings, and literary descriptions of texture. Distinguished from 平滑 (flat and smooth) by a stronger tactile quality.

Examples

1. 大理石地板经过打磨后显得格外光滑，走路时需格外小心。 After being polished, the marble floor looks exceptionally smooth, so you need to be extra careful when walking.
2. 婴儿的皮肤柔软光滑，令人忍不住想要轻触。 A baby’s skin is soft and smooth—you can’t help but want to touch it.
