Adjectives and (some more) präpositions are needed in the Colognisn (ksh) GRAMMAR function. For an example of the need of präpositionis, see URL https://translatewiki.net/w/i.php?title=MediaWiki:Mobile-frontend-regular-site/ksh&action=edit&loadgroup=ext-0-wikimedia-main&loadtask=untranslated
Please provide a patch.
Can't do anything without patch. There is nothing in MW that prevents doing this.
As you write, nothing in MediaWiki prevents doing it. Thus this not an invalid, but an unsolved issue. Reopening Providing a patch is a matter of available time, priority, and most likely needs a redesign of parameter passing to GRAMMAR for the language.
I don't think any redesign is needed. Why must this bug be open if we cannot do anything to fix it?
