Dear Civfanatics, I am about to translate a book from eng>german, it's about autoimmune diseases, but the topic is clear to me. On the other hand, I sometimes bump into typical expressions that I do not fully understand, and where dictionaries cannot help me. I suppose there are lots of native speakers around, and would love to get some short help. No need to speak german nor to understand medical topics, it's all about explaining me in short words, what expression XY could possibly mean. Thanks for your help, if you want to do this. The author is an American PhD but I would reckon he uses quite common language.
