Preventing English text in German book from adding to my known words
If on computer use X to ignore
After importing you can edit the lesson and delete those sectionas...I assume you're talking about the beginning of books that may have a lot of English from the publisher?
You can also leave all this in and just click ignore of all English words as you come across them.
Sadly I don't think this is possible as I noticed the same problem for Portguese with basic stuff like names of people or letters or organizations...very frustrating but it is what it is. If it would screw things up more then I'm fine with it as it is.
