I feel that this questions must have been asked before but couldn’t find it on the forums.
So what I want to know is how can I see the words that he systems sees them as know? And also, I’m interested if I can remove them from list so I could relearn them.
As far as I know there is no list of “known” words. I believe you can highlight any white word in your texts, ie the ones that the systems regards as known by you, and relearn them to your heart’s content. As the Canadians are having a long weekend you may have to wait a bit for a proper, technical explanation.
Sanne is correct. There is no such list. If you come across a white word and don’t feel you fully know it, you can save it again. I do this all the time. Our known word list should soon reach into the tens of thousands so review a list might be difficult.
