OT: Is Finland a Germanic nation? Their language isn't afaik.
No. Finland speaks Finnish and Swedish, and they lie within the Nordic region.
Well that doesn't really exclude them since Swedes and Norwegians are Germanic. After more research it seems that Finns are a distinct ethnic group though their origins are somewhat uncertain https://en.m.wikipedia.org/wiki/Finn
In any case, it's all pretty irrelevant to the site.
Definitely Finish as a language is completely unrelated to any Germanic language.
Grammatically you're right but due to the Baltic trade, the Swedish occupation and various other historical reasons there is a lot of Germanic vocabulary in Finnish etymology, though many words of Germanic origin are no longer recognizable. Estonian, a very closely related language, has kept some of those in an earlier form where they are more recognizably Germanic.
