title_body: Grammar concepts required for every conlang Is there a method to make sure that a constructed language contains all the necessary grammar concepts, e.g. to make sure that a concept like genitive case or a construct state is present?
  
  For example, is there a list of such concepts available?

  The primary issue here is trying to find out what is necessary for a language to function; not even 'Chomskyan tenets' like recursion (or broader concepts like classifiers and numbers) seem to be obligatory, and language in essence seems to boil down to a glorified predicate machine with parts tacked on by Broca's area — and so, the answer is, for now, no: we'd very much like to see a way of doing this, and it would be truly groundbreaking in linguistics, seeing as it's a major focus point for many researchers in many fields of philosophy, linguistics, psychology and neurology.
