I can confidently say that I speak Portuguese, Spanish, and English to varying degrees. However, at a beginner level, I know Norwegian, Italian, and Polish. I also am probably at a very beginner level in Russian and French, both of which I’m learning and getting better at. I’m conversing with French people.
My fiancé says I’m a polyglot, but I don’t know if I’m just trilingual or not.
I was moreso referring to their alphabet and pronounciations but a lot of them such as German have a hefty amount of Latin terms which got incorporated. I doubt many Germans these days would understand original Germanic.
They do have their own roots but you get a head start in Europe by pronouncing Latin words in whatever regional accent is availble. Polish and Norwegian likely less but OP is still at a beginner level for those.
But for example adding Japanese, Chinese or Arabic adds a whole new alphabet and experience where there is virtually no Latin base to start from
