Kebei /kʼɛpɛi/ is a speed-conlang built for a challenge over the course of under 14 hours. The entire creative process was livestreamed, and the VODs are available on youtube. The final PDF can be found here.
Vahn /væn/ is an oligomorphemic language built of around 37 morphemes. It has been heralded a number of times on the subreddit and it’s associated communities as “the good oligomorphemic language”. Ultimately however, it remains extremely poorly documented, with the best documentation coming in the form of a document I made in MS Paint when I was still actively working on the language. It was successfully taught to one other person to a high standard, and a few to a lesser standard, and thus I believe it to meet the minimum requirement for being successful when it comes to oligomorphemics.
