It's like a schoolhouse mentality.
Oh get off it. First of all, native speakers of English aren't going to know the terminology you're using (terminology you are using without understanding, by the way) and they're going to be providing answers based on their idiolect. In fact, you don't even know that your respondents are native speakers.
You're asking directed questions from an academic context, but you didn't provide the context. My query was a query -- I didn't make an accusation, I merely said "Please tell me we're not doing your homework for you?" It's a reasonable question, particularly given the inadequate context you've provided.
Secondly, NNES or not, you are asking questions that suggest that not only are you not a native speaker of English -- which is fine; there's no reason you should be -- but
you don't know the basics of the field you're studying.
By basics, I mean the sort of thing covered in a introduction to linguistics for undergrads who are not themselves linguistics majors.
By basics, I mean you don't even seem to have enough of a clue to use a dictionary -- which would answer a fair number of your questions.
By basics, I mean you don't seem to even understand that language exists in context, both in a particular context (where the instances occur and the language surrounding them) and a social context (why you are asking the questions) indicates, well, the kindest thing I can say, is that it suggests a paucity of thought.
It's a little odd, possibly even disconcerting.
Graduate courses do involve homework, they do involve independent study, and the idea is that
you do the work, not ask someone else for the answers.
I suggest you get yourself a very basic introduction to linguistics text, and a history of the English language text and start perusing. You might then pick up one of the English grammar texts for specialists, since they tend to explain the various systems of grammar terminology and ways of looking at English grammar and syntax, most of which frequently seem to make very little sense when used in the aggregate. You might also watch for the grammar texts by Marianne Celce-Murcia, since she covers a lot of the usage and grammar of English specifically for NNES and ESL teachers. Her work is extremely well-regarded and astonishingly helpful in making sense of our beloved but bizarre language.
I wish you well in your course; the prognosis is less than positive, if this is your usual approach to learning.
