来自拉丁语domus, 家，词源同domain. 引申词义天主教教堂，穹顶。

dome: dome: [16] Dome originally meant ‘house’ in English – it was borrowed from Latin domus ‘house’ (source of English domestic). However, in other European languages the descendants of domus had come to signify more than a humble dwelling house, and its new meanings spread to English. The word increasingly encompassed stately mansions and important places of worship. Italian duomo and German dom mean ‘cathedral’, for instance (a sense adopted by English in the late 17th and early 18th centuries), and since a leading characteristic of Italian cathedrals is their cupola, the word was soon applied to this.

dome (n.): "round, vaulted roof," 1650s, from French dome (16c.), from Provençal doma, from Greek doma "house, housetop" (especially a style of roof from the east), related to domos "house" (see domestic).

In the Middle Ages, German dom and Italian duomo were used for "cathedral" (on the notion of "God's house"), so English began to use this word in the sense "cupola," an architectural feature characteristic of Italian cathedrals. Used in U.S. also with reference to round summits of mountains.
