Wow, if you say 'Mannen ater brod' again and again, it sounds like what it is trans. to: 'The man eats the bread'. Well, kind of. My question is, do some words sound like English because, Sweden and Germany were close at one time, and English gets part of German words? Or is there another reason?
No, but it sounds correct here. I think you may be expecting the wrong sound - Swedish vowels can be long or short, and the e is short in both of those cases. These videos on Swedish vowels are really helpful: https://www.youtube.com/channel/UCUb87YTKOTgnGcAM4toC-6A
