sl-predicative
Fragment of a discussion from User talk:Rua
It's more that I'm not familiar with this word, and most other users of Wiktionary won't either. If it's a commonly accepted form then we should probably keep it, but we should find some way to describe what it actually means, maybe in Appendix:Glossary or something.
I'll ask in the Information Desk to see if anyone can help with this. You can join too if you want to.
