Thanks a lot!!
so. (someone), sth. (something) are common abbreviations in German-English dictionaries.

Sorry, I thought it is international.
It's difficult for me to explain. All those expressions above-mentioned have the same meaning in German. There is one German expression for all these English ones.

Obviously, some don't exist at all??!
Let me give you an example to show you what I mean (sorry, I have to cite a dictionary, it's easier for me

)
