May I introduce you to the German language?
We have "gesundheitszeugnis" (health certificate) and "bärenstark" (strong as a bear), and of course "[der] Donaudampfschifffahrtsgesellschaftskapitän" ([the] Danube Steamship Navigation Company Captain) and "[Das] Rindfleischetikettierungsüberwachungsaufgabenübertragungsgesetz" ([the] cattle marking and beef labeling supervision duties delegation law).
And we don't expect dictionaries to contain every compound word you could come up with in German either.
Added a German/Norwegian section — but vidarh corrected me below: German doesn't 'remove the space,' the compound never had one. Adding a space changes the meaning or breaks the grammar. The article now reflects that.
