scoundrel (n.)youdaoicibaDictYouDict[scoundrel 词源字典]
1580s, skowndrell, of unknown origin. One suggestion is Anglo-French escoundre (Old French escondre) "to hide, hide oneself," from Vulgar Latin *excondere, from Latin condere "to hide" (see abscond). The main objection to this theory is that hundreds of years lie between the two words.[scoundrel etymology, scoundrel origin, 英语词源]
