滑梯
huá tī · HSK 7
a slide
🛝 滑 (slippery/slide) + 梯 (ladder/stairs) = the slippery ladder kids climb up and slide down
滑 huá means slippery or to slide; 梯 tī is the same 梯 as in 梯子 (ladder) and 楼梯 (stairs). Together: the ladder-and-chute combo on a playground.
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.'
