Just a remark. "Brat" and "Grill" is not the same.
"Ewas braten" would be "to fry something [in a pan]"
But there is a little more to it. You can make a "Braten"[<-Noun] (Here an example of a Braten made from Pork [=Schwein]:
Pork-"Braten")
A "Braten" can be made in a pot (=braising) or in an oven. An oven (=Ofen) is often called a "Brat-Ofen" (Fry-Oven) Sometimes also called "Röhre" (=tube) [Just Röhre (Tube) or Bratröhre (Fry-Tube)]. In former times an oven would be more like a tube and there was fire in it. So, compare it to a barbeque. It this you also can fry something.
A "Braten" would be a good example because it is often made in an oven.
But yes, Bratwurst is often grilled, because "braten" means, to coock something without or with an extreme low amount of liquids or extra fat. So, while "braten" (frying) mostly refers to cook something in an oven or in a pan, it also can refere to "frying on an grill". Meaning, grilling is a smaller, specific part of frying, at least in German.
By the way, the inside of a "Brat"wurst is called "das
Brät"
