Constructed languages, such as Quenya or Klingon, are a fascinating topic and can be an amazing way to bring a culture to life. We already have a question on the topic:
On the other hand, there is also already a Linguistics.SE which might be better equipped to answer such questions. While clearly related to worldbuilding, it's a specialized-enough discipline that I'm not sure that worldbuilding experts are going to necessarily be experts on it – while linguistic experts seem pretty likely to be, or at least give legitimately educated conjecture.
But it's still pretty obviously related. Does Worldbuilding.SE think it can handle constructed languages? When do questions about constructing languages go beyond our purview, into the realm of Linguistics?
