The town's name, Wick, comes from the old Norse word 'Vik' which meant 'bay'. The Norse pronounced 'Vik' as "Week' (indeed the word 'Viking' or 'vikngr' was pronounced 'weekinger'), which is how the town is still known in Caithness to this day.
The other main settlement in Caithness - Thurso - takes its name from the old Norse term for 'Thor's river' - 'Thor-sa' or 'Theorsa'. Locals still refer to the town as 'Thursa' with a soft 's', never a hard 's' or 'z' sound. Thursa, not Thurzo.
There's no escaping the Norse influence in Caithness.
