köken: */tenzjau/ → /tenʑjɔː/ → /tend͡ʑoː/ From Old Japanese, in turn from Middle Chinese 天井 (MC then tsjengX). First cited in Old Japanese to a work from 759. The word is literally spelled 天 (“heaven, sky”) + 井 (“well, wellhead”), in reference to the way that ceiling beams were arranged in the shape of a wellhead.

roof (top of a building or other object one can enter)
köken: First attested in the Gugeupbang eonhae (救急方諺解 / 구급방언해), 1466, as Middle Korean 집웋 (Yale: cipwuh), equivalent to Middle Korean 집 (cip, “house”) + 웋 (wuh, “top”) (> Modern Korean 위 (wi, “top”). The modern Korean form does not derive directly from the Middle Korean form but from a different reflex of Old Korean 上只 (*WUk), in which */k/ was nasalized instead of being lenited to /h/. The original /k/…
Inherited from Sanskrit *छत्ति (*chatti, “covering, roof”), from the root छद् (chad, “to cover”) + -ति (-ti). Displaced Old Hindi छात (chāta), from the same Sanskrit source.
