I'm working on a conlang at the request of a script-writer who wants something very accurate. No problem for me since I spent a lot of time describing minority languages. The point is, the producers request a very realistic grammar so that future episodes can be consistent. Fun.
Long story short, this conlang has several dialects. While the dialects are distinguished mainly by morphology and lexical differences, there are some minor phonological differences, too.
For example, there is a kind of uvular harmony in dialect 1 but not dialect 2
Dialect 1. xeqepo
Dialect 2. heqepo (x-initial words are disallowed)
Simple, right? Sure.
The question is, were this a natural, human language, which would more likely be the more conservative dialect (based on this particular property alone). i.e.: Is it more likely that there's a rule
or like this?
