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. => domestic[dome etymology, dome origin, 英语词源]
