I never got taught any grammar until around GCSE time. Then I had a new English teacher who'd just started teaching and felt that we should know some English grammar at least. A lot of people I know would be hard pressed to say what a noun, verb, adverb etc... is and they've all got university degrees so it's not for lack of trying.

I've been told that if you learn Latin then you get a good feel for English grammar.
