sark (n.)youdaoicibaDictYouDict[sark 词源字典]
"shirt, body garment of linen or cotton for either sex," late Old English serc "shirt, corselet, coat of mail," surviving as a Scottish and northern dialect word, from Old Norse serkr, cognate with Old English serk (see berserk). But Gordon lists it as a loan-word from Latin sarcia; other sources are silent on the point. Lithuanian sarkas "shirt," Old Church Slavonic sraka "tunic," Russian soročka, Finnish sarkki "shirt" perhaps are all from Germanic.[sark etymology, sark origin, 英语词源]
