breed of cattle, 1834, from the Channel Island where it was bred; the island name is Viking. Like neighboring Jersey, it was also taken as the name for a coarse, close-fitting vest of wool (1839), and in Australia the word supplies many of the usages of jersey in U.S. The second element of the name is Old Norse ey "island;" the first element uncertain, traditionally meaning "green," but perhaps rather representing a Viking personal name, such as Grani.
