Old Norse víking (“marauding, piracy”) itself is from Old Norse vík (“inlet, cove, fjord”) + -ing (“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.
