Hey there. I need some help as I will be writing up law essays. My grammar is good, but I can't get my head around relative restrictive and non restrictive clauses; I really don't want this to effect my essay writing, as I was never taught this in school or college. I was just doing some research and recognised the existence of relative clauses, and that they can be restrictive and non restrictive. Before I used to use a comma before which in every instance, and now after what I have just read I feel uneasy and don't know whether to place a comma or not. However, I never use a comma before "that" in any instance.
Also, I never use a comma before "when" and "where", as to me these are subordinating conjunction and a comma should never be before it, if it follows an independent clause.
Is there any department in university where I could go that will help me?
Please help me with my question. Just need help. I need to know if I'm correct with the way I use commas before "which" in every instance, and not before "when" and "where".
I'm just getting anxious!!!
