You would also be more likely to use konung in some expressions, such as skogens konung (king of the forest), which usually refers to an elk, djurens konung (king of the animals), which is a lion, or konungarnas konung (the king of kings), which usually refers to Jesus. Both kung and konung originally stem from Proto-Germanic *kuningaz, which also meant king, but there appears to have been a distinction between the two words for much of Swedish history, as there are also two separate words for king in Old Norse: kongr and konunger.
