One of the trickiest things about understanding grammar is that the people teaching it use all these crazy scientific words which make the whole thing sound like a terrifying gynecological procedure. Here you can find brief (well, as brief as I can manage) explanations of all the grammatical terminology and foundational grammatical knowledge you might need to make sense of our grammar lessons. These kinds of things will also be linked in every lesson for easy access. I hope this helps to make the experience less scary.
