<p>I’m 100% sure you don’t need one before because (because the subject before and after “because” is the same), but as far as the “rather” is concerned, it’s more of a gut feeling that you don’t need it.</p>
<p>I thought that if the subject of the clause after because was different than the subject of the clause before and is a full sentence, then you needed a comma.</p>
<p>ex.</p>
<p>John went to the store, because Martha wanted him to buy eggs.</p>
<p>I don’t know, I never use “because” in formal stuff so I never think about it…haha.</p>
<p>Must be a new rule then, because I remember it being drilled into my head SO many times…(^look, I did it up there). Maybe it depends on the conjunction.</p>
<p>Edit: This is totally driving me insane now, lol. Most reputable sources online seem to say you never need a coma before “because”, because (OMG, I can’t stop!) by definition it introduces a subordinate phrase, and you only need commas to separate two…I guess…nonsubordinate phrases. Or something. Like when using “and”. </p>
<p>OK, I’m so going to ask my English teacher.</p>
<p>yup, that’s exactly it. if the two parts can be completely seperate and still make the same sense then it’s the “, and” thing, but you never need a comma with “because” because the two have a relationship that is necessary for it to have the same meaning. That didn’t make a whole lot of sense, so here’s an example:</p>
<p>Mary went to the park, and John went skiing.
has the exact same meaning as:
Mary went to the park. John went skiing.</p>
<p>whereas</p>
<p>Mary went to the park because John went skiing.
has a different meaning than
Mary went to the park. John went skiing.</p>
<p>but you usually wouldn’t use a comma in the first sentance either.
Mary went to the park and John went skiing.
Is better than if there were a comma before and.
The difference between cooridnating and subordinating conjunctions doesn’t have to do with commas in that way.</p>
<p>A friend of mine (a teacher as well) tells me that in England a comma is used before the word ‘and’ and the word ‘or.’ That’s not the case in American English (you can do with or without it in some cases).</p>
<p>As for commas before the word ‘because’ here is an example of where the comma changes the meaning of the word and where it would be necessary.</p>
<p>No comma needed: John bought Chelsea new sunglasses because he wanted to get her a present for her birthday.</p>
<p>Comma needed: I knew John would buy Chelsea new sunglasses, because he left me a message on my cell phone asking which brand to get.</p>
<p>Without the comma in that last sentence, the sentence would sound like the message that John left me caused him to buy Chelsea new sunglasses.</p>
<p>To the OP: Your original sentence does not need commas. 13351 was right. Your sentence should look like this: “Jerry decides to hug Tom because his conscience views Tom as a friend rather than as an enemy.”</p>
