"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. Cf. also Lithuanian sarkas "shirt," Old Church Slavonic sraka "tunic," Russian soročka, Finnish sarkki "shirt," all of which perhaps are from Germanic.
one of the Channel Islands (q.v.), in the English Channel. Sark lies 7 miles (11 km) east of Guernsey and about 25 miles (40 km) west of the Cherbourg Peninsula of France. It consists of Great Sark and Little Sark, which are connected by La Coupee (a 300-foot- [90-metre-] long isthmus that is only about 30 feet [10 m] wide), and is 3 miles (5 km) long and 1.5 miles (2.4 km) wide at its broadest point. The smaller, privately owned island of Brecqhou (Brechou) is separated from Great Sark by the narrow Le Gouliot Channel. The total area of Sark, including Brecqhou, is 2.1 square miles (5.5 square km). Sark is part of the Bailiwick of Guernsey. The island is essentially a plateau rising to 375 feet (114 m), with a scenic coast encircled by precipitous cliffs. The island has three small harbours: Creux, La Maseline, and Havre Gosselin.
