In English, the same set of coordinating conjunctions can be used to join elements of nearly any syntactic type. E.g., you can have <verb> "and" <verb>, <noun> "and" <noun>, <clause> "and" <clause>, etc., and the form "and" never changes. Same with "or", "nor", "not...but", etc. Armenian, in contrast, has distinct sets of conjunctions for clauses vs. everything else. This is useful in resolving ambiguity in sentences like "I dance and go on walks with Erin", which can resolve as "I (dance and-VP go on walks) with Erin" or "I dance and-CP [I] go on walks with Erin." I borrowed that distinction to use in WSL, but I don't think I have ever seen it elsewhere. Do anybody else's conlangs have these kinds of heterogenous conjunctions? If so, do you make more levels of distinctions in what sets of conjunctions can be used with what categories of syntactic nodes? And does anyone know of other natlangs that makes this kind of distinction?
