virtu (n.)youdaoicibaDictYouDict[virtu 词源字典]
"excellence in an object of art, passion for works of art," 1722, from Italian virtu "excellence," from Latin virtutem (nominative virtus) "virtue, goodness, manliness" (see virtue). The same word as virtue, borrowed during a period when everything Italian was in vogue. Sometimes spelled vertu, as though from French, but this sense of the word is not in French.[virtu etymology, virtu origin, 英语词源]
