Can somebody explain this category? I'm confused. 2602:252:D2B:3AA0:545:6E7:D61E:FAB5 12:21, 12 July 2018 (UTC)
 * Given the sheer number of pages we have, messages on talk pages usually won't be seen. But, Danish transitioned from having multiple cases to having only a genitive marked by -s. Certain fixed phrases involving case forms of nouns remain, with those case forms only surviving in these phrases, having no meaning on their own anymore.__Gamren (talk) 13:06, 11 June 2020 (UTC)
