E.g. transformational grammars or probabilistic grammars deal with language structures, branching, semantic ranging, etc. They are dealing with more or less 'rational', or logical cocepts.
But what if there are grammar which cover such aspects, as ethics (like any language with honorifics, or with status sociolects, like Tamil), or grammars of emotions (from Tamil concepts of agams to emotions coded in grammars of Australian and Amazonian languages)?
What are the exact domains of language grammars? Are they ontological, and if they are, is that explicitly or implicitly determined?
