Originally an unorthodox variant of 牀. Now made up of 广 (“house”) + 木 (“tree”), an ideogrammic compound (會意 / 会意) representing a wooden furniture item (a bed) in a house.

Schuessler (2007) suggests that it may be related to Khmer រង (rɔɔng, “to support from below”), Old Mon (joṅ, “couch; bedstead”). Compare also Burmese စင် (cang, “platform, stage”) (Luce, 1981).

From Old Japanese. Attested in the 日本書紀 (Nihon Shoki), completed in 720 and one of the earliest works written in Japanese (see Wikipedia:Nihon Shoki), with a meaning of bed.

According to the 和句解 (Wakuge), published in 1668 by early Edo-period scholar Matsunaga Teitoku (松永貞徳; see Wikipedia:ja:松永貞徳), derives from ゆか (yuka) as the 未然形 (mizenkei, “irrealis form”) stem of the verb 行く (yuku, “to go”) of an original meaning similar to "not going", in reference to a place where one sits down to rest.

⟨to₂ko₂⟩ → /toko/

From Old Japanese. Cognate with 所 (tokoro, “place”). Attested since at least the Nara period, appearing in the Man'yōshū, completed in 759.^[3][4]
