That explains it. Finnish is not «Norse»

In English the closest words we have are grit, guts, and resilience. Also the name of a fun dumb action movie where a Finnish dude finds ways to creatively kill a lot of Nazis.

My apologies if I’m mistaken but I think Norse is generally used to refer to Nordic languages in general. Likewise, the terms “Norsemen” and “Northmen” are/were used to refer to the Nordic people in general (which would stretch as far as Iceland and the Faroe Islands as well as the early Normans), not just Norwegians.
No need to apologize buddy! It’s all good. Finnish is a completely different language for some reason. Swedish Norwegian Danish and Icelandic are basically the same.
