Modern Scandinavians say ‘Tor’ and not ‘Thor’. For comparison here are the days of the week in Skandi: mandag, tirsdag, onsdag, torsdag, fredag, lordag, sondag. The days of the week are not capitalised. Sondag is named for the sun, mandag is named for the moon, (mÃ¥nen), tirsdag is named for the old god, Tyr, onsdag is, indeed, named for Odin, torsdag is named for the god Tor or Thor as it got used in English, fredag, is named for the mother of the gods, Frigg/Freya and laurdag, or ‘lordag’ is named for what what was done on this day, bathing. The English kept the Roman word for that day, ‘Saturday’. The languages have evolved a great deal over the centuries. If you want to hear something close to what the ancient Norse spoke, you’d want to go to the Shetlands and Orkneys and listen to some Norn or to the Faroe Islands and hear some Faroese. If you went back to London in the 14th or 15th century, you’d have a very hard time understanding their English. Just pick up a copy of The Canterbury Tales, unabridged, and try to read it. It’s English, but just written a very long time ago. All languages evolve through time. Having said that, the Marvel Universe is not pronouncing things correctly and it makes many a stomach turn.
