Översättning - Latin-Engelska - amo lucifer undo

However, there seems to be mistakes with the adjective lucifer and undo. Wave is unda (f) and it would seem that it should be in the accusative as undam.
In this case, the adjective should be luciferam.

There is a ralated verb undo which means "I surge, undulate" (as in waves) but this would not make sense here.
