First of all, I am aware of the fact that there is a dedicated linguistics thread.
But at least to me, it seems that there still would be a reason for opening the one you are reading right now, because I am not really asking an in-depth linguistics question.
This is about something different. It is about how exactly reading more about linguistics could help learning languages in the way I do it, i.e. by immersion and exposure only. That also includes looking up unknown words and reading textbooks that contain grammar explanations. However, I entirely avoid intentional attempts of memorizing words, grammar or anything else. All of it is done on the base of "whatever sticks that sticks, and whatever doesn't, I don't worry about it because there also are other ways of expressing the same ideas using different words, even if they are more basic".
So how exactly can reading more about linguistics when someone is learning languages that way help? Also I should note that I personally, without wanting to offend anyone of course , am not interested in any theoretical linguistics questions that aren't connected to some Applied Languages Purposes.
