The last d in "død" should be pronounced (when "død" is a noun): http://forvo.com/word/d%C3%B8d/#no
Jeg sørger over Chester's død. :(
Jeg og sørger over Chesters død
Why not also "her teacher's death"?
The suggested translation 'she is sorrowing the teacher's death' doesn't make sense. It should be 'sorrowing about' and even that is very old fashioned.
