Personally I stopped studying English Grammar the traditional way years ago.
By now I’ve actually forgotten most of the grammar terms and rules I had hammered into my brain, and just as well – they only prevented me from speaking English fluently.
Simple enough – I used to spend way too much time analyzing my thoughts, applying Grammar rules and preparing my speech in my head.
It was killing my English fluency, and it took me quite a while to figure out the simple truth – English collocations (phrases, idiomatic expressions, most commonly used sentences) already contain all necessary grammar in them!
When I speak English now, I don’t think about grammar anywhere near as much as I used to. I just rely on my “gut feeling” and get fully involved in conversations. My intuition takes care of English Grammar!
