I was browsing the web, and I came across this language.
From a first glance, the language seems to emphasize regularity and expressiveness, being "underspecified by default [but] extremely precise on demand". The language's rich morphology reminds me a bit of Ithkuil. But I don't know much about either Ithkuil or Qþyn|gài, so I don't know how useful that comparison is.
I haven't really read that much about this language yet, but the introduction intrigues me so I'll look into it and see if there are any grammatical features that I really like!
