It's "ja", not "jah". The German language also uses the aitch for many purposes, but not to modify vowels...

...as you must in English, or otherwise you'd read every "a" as "ay", so you need to write "ah" to pronounce it as it was before that vowel shift.

Well, I'm not interested in that if the lender is charging too much interest.

"stb" is for Hungaian "és a többi" - and the more(s). The és is often abbreviated in speech to just s (pronounced sh).

"itd" is Serbian (and the Russian is almost identical) for "i tako dalje" - and so further - to differ from the German "and so wider".
