Hi, I'm new .. I really should post some kind of introduction where it's proper, but this really is my biggest concern right now. I'm having a colossal problem with a certain aspect of editing - this silly comma before 'and.' I'm not talking about if it's in a list, like "I bought apples, juice, and eggs." That's fine. But in sentences like this: Kai spit a bit of tea out of her mouth and Noma almost choked on a piece of buttered bread. Someone who is helping edit a story of mine explained to me that a comma is needed before 'and' because this sentence is comprised of two independent clauses. Okay, fine. Live and learn, right? (this isn't the sentence her and I discussed - this is one she missed, but fits the point I'm making.) Then, she also insisted sentences like these need a comma before 'and' as well: The blonde took a few steps into the room silently, and placed the neckpiece down on the table. That's not two independent clauses. However, she explained that 'the blonde' is implied in the second part, as in "The blonde placed..." An easier equivalent would be, "She took a few steps into the room silently, and placed the neckpiece down." A 'she' is evidently implied before 'placed,' making it two independent clauses. (This might be a horrible way of explaining it, but it's how I understood it.) Okay, again. Live and learn. However, I had been waiting for her to e-mail me back some answers on some edits and I had figured I'd look over what has already been edited of the story - just to be thorough. I found a great deal of instances where there were two independent clauses connected by an 'and' where she didn't direct me to put a comma before it. And there were even more of that 'implied' stuff I just explained. So what's right and what isn't? I did a little research and it seems that if there are two independent clauses, you need the comma before the 'and.' (She tied her pink shoes, and he closed the tan door.) Although, it certainly makes the sentence look cumbersome, no? And it's certainly a rule I have never encountered before. However, that 'implied' thing. I found no examples of that anywhere. I finally did discuss it with her, the person helping me edit one of my stories, and it really didn't prove to help my understanding - especially with that 'implied' stuff. When should there be a comma before the 'and'? Two independent clauses? The 'implied' thing? What? You see, I'm doing extensive editing on a story of mine, if you didn't get that idea by now .., and there are a lot of sentences containing, or that might contain, this 'and' instance/problem. And I don't understand if a comma should be placed in them or not. If I posted a whole bunch of sentences on this thread, could you all help me fix them? Or is that no good here? Either way, I really need help with this comma before the 'and' rule. So confusing!
