obwohl is the translation in German. It is translated from English to German. German is mostly spoken in the European countries.
English: bra = brassiere = German: BH or Büstenhalter. OR the improved version is: keypsumfromfloppin'. You have to say it fast though.
English: "we" is German: "wir". It is pronounced "Vir" though; "W" in German make "V" sounds.
Though I'm not German, I just learned it in school, I believe the translation would be: Strenges Geheimnis ..
The literal translation would be "all das Beste", though a German would rather say "alles Gute".
Großvater. We don't use it though. It's "Opa" what we say.
goofy = albern Walt Disneys Goofy is also "Goofy", though :-)
With learning, like every language. Some say German seems to be more guttral a language than others though
OK, is OK in German too. They tend to write it out as "okay", though.
There is no Halloween in Germany, though because of movies it is becoming more popular. So if you mean october 31 then it is "Halloween" in German as well
It would be : "entschuldigung"(short form: schuldigung) or "tut mir leid" (litterally: I'm sorry) though German youth does say "sorry" now with a German accent that swallows the "rr"s
Er ist junger als ich. I'm pretty sure that's how you say it, though I'm not 100%. It's definitely something along those lines though!
Kopenhagen Kopenhaven, like Bremerhaven
