The duck got the duck's place = "Anden fik andens plads".
The duck got someone else's place = "Anden fik en andens plads".
The duck got second place = "Anden fik andenpladsen".
Someone else got the duck's place = "En anden fik andens plads".
Another duck got someone else's second place="En anden and fik en anden ands andenplads".
Best of luck to you if you ever have to report from a competition involving ducks in danish.
There's a slight difference in the pronunciation of "anden" (the duck) and "anden" (second), at least, so that's something. Doesn't help you one bit in writing, though.
You could also spice it up by saying "blev nummer to" (became number two) or "fik sølv" (got silver).
I wrote "First, the duck, Third" and it said incorrect???? did i do something wrong???????
this finally explains why in english one says "every other day" meaning "every second day" (english is not my first language)
