Viking แปลว่า

Borrowed from Old Norse víkingr (“Viking”). Already in Old English as wīċing and Old Frisian wītsing, but assumed extinct in Middle English and borrowed anew in the 19th century; any survivals in dialect through the Middle Ages are unknown. Old Norse víkingr itself is from Old Norse vík (“inlet, cove, fjord”) + -ingr (“one belonging to, one who frequents”) (the -r is the nominative desinence). Thus, “one from or who frequents the sea’s inlets”. The Old English and Anglo-Frisian form, existing since at least the eighth century, could also have been derived from or influenced by Old English wīc (“camp”), on account of the temporary encampments which were often a prominent feature of the Vikings’ raids. Others proposals were made, like e.g. deriving víkingr from the root related to the verb víkja or deriving both English and Old Norse words to *wīkingaz related to víkja or wīc.
