Yes, ongoing discussions about phonology can still invalidate whatever we discuss here, but in phonology discussions I feel like a fish out of water.
So... To start the discussion: I have been thinking about tenses and that they are not in all languages, especially creoles often lack them and compensate by a rich aspect system. These languages are supposed to be easy, our language is also supposed to be easy or at least not too weird, so I suggest that we also have something similar. I propose a perfective, progressive, inceptive, terminative, habitual, and maybe also pausative and resumptive aspects. Anyone with me?
