床
ゆか · yuka · JLPT N3 · noun
floor
🪵 床 = 广 roof + 木 wood: the wooden boards under a roof
Sound hook: yuka sounds like yuck-a, which is what you say when food lands on the floor. Careful: in Chinese 床 means bed, and in Japanese the reading toko also means bed or alcove. Read as yuka, it means floor.
床 — 广 (shelter) + 木 (wood)
床 combines 广 (a roof or shelter) with 木 (wood), depicting a wooden piece of furniture kept indoors. Originally it referred to a low wooden platform or couch used for sitting and sleeping. Over time the meaning narrowed mainly to 'bed,' though it still appears in compounds for table-like stands.
