I'm not sure if this question is too broad, but I'll give it a try.
Noticing how "yet"/"still" is the same word as "again", that is, "encore", I get the feeling I will stumble with some ambiguities in the long run (right now I can't think of any, though).
Have you run into any ambiguities using this word? Is there a guideline of some sort to make the distinction?
