Wie bitte?!
Regards,
Sehr gute — my German is barely passable - I could speak it well enough at a b1 level until I moved to Poland and started learning polski. Then zero. Now my son has German at beginner level, so I’m at A1 level.
the term is “Urheimat” - not the uhrmheit I wrote, sorry
But basically I thought it was now an English linguistics term in common usage.
it means homeland
