⛸️ 滑 = slide + 冰 = ice; to slide on ice is to skate
滑 huá means slippery or to slide; 冰 bīng means ice. Skating is sliding on ice. 冰 bīng also sounds like the start of the English word for the cold white stuff before it melts.
滑 — water radical 氵 + bone 骨
A semantic-phonetic compound: 氵 (water) gives the meaning of slipperiness, while 骨 (bone) supplies the sound. The original sense was 'slippery,' as water makes surfaces hard to grip, and it later extended to 'smooth' and figuratively 'cunning' or 'sly.'
冰 — ice radical 冫 + water 水
冰 means 'ice' and combines 冫 (the 'ice' radical, originally a pictograph of ice crystals) with 水 'water'. The radical 冫 is itself a simplified form of an older character for ice, so 冰 is essentially 'frozen water'. The form 氷 is a variant still used in Japanese.
