Ok, now I know what you mean.
Besides 4 other languages I speak fluent German. I believe this is the longest word in the German language.
Rindfleischetikettierungsüberwachungsaufgabenübertragungsgesetz 🙃

Was but has been dropped

The longest German word that is not created artificially as a longest-word record seems to be Rindfleischetikettierungsüberwachungsaufgabenübertragungsgesetz at 63 letters. The word means “law delegating beef label monitoring” but as of 2013, it was removed from the books because European Union regulations have changed and that particular law became obsolete, leading to news reports that Germany “had lost its longest word”.

I also speak German and this Grundstücksverkehrsgenehmigungszuständigkeitsübertragungsverordnung is the longest German word, see for example here https://www.buzer.de/gesetz/5188/index.htm

Do you agree that this превысокомногорассмотрительствующий is the longest Russian word?
