Yes, hallo is the German word for hello.
These German Pennsylvania immigrants are called the Pennsylvania Dutch, a misnomer- the German word for German is "Deutsch," but these people were mistakenly called Dutch.
The German word is "Hallo" or "guten Tag"
esse
hinkel
"Goudentag" is not a Danish or German word. It does not have a known meaning in either language. It might be misspelled or a made-up word.
The expression "Pennsylvania Dutch" referring to this group of people is an alteration of the word "Deutsch" meaning "German." The Pennsylvania Dutch are actually as much of Swiss origin as German.
pretty = hibsch
Hallo Guten Tag
, it is the same word, though in German it is hallo
to bake (verb) = backe
Apple = AppelApples = Eppel
