床

Mixed phono-semantic/semantic compound:

广 (엄, “house, shelter”) — denotes building/interior.

木 (목, “wood”) — originally the phonetic element (from 牀), also adds meaning “wooden structure.”

Thus “a raised wooden structure inside a house,” i.e., a bed, couch, or platform.

In Korean: especially refers to 평상 (wooden outdoor platform/bench).

病床 (병상) — sickbed, hospital bed

平床 (평상) — wooden outdoor platform/bench

床頭 (상두) — bedside, bedhead

床板 (상판) — bed board, wooden planking

Semantic shift:

In Middle Chinese, 床 meant folding wooden chair (胡床) or indoor couch (榻).

Modern Chinese: primarily “bed.”

Japanese: “bed, raised floor, or floorboard.”

Korean: especially “평상,” a large wooden bench/platform, often outdoors.

Traditional form: 牀 (U+7240), still used in some contexts.
