I'm all with rubah in the sense of lists. Which is what I thought they were for, besides the whole time thing, such as 1:32. I've mostly only ever used it to set off a list. Occasionally something like "Then he said it: Blah blah blah".
But let me pull some sentences from the book I referenced:
Quote:
"Stop — STOP!" Harry shouted, but as he looked back again two jets of green light flew past his left ear: Four Death Eaters were keeping up with the bike; more curses shot after them, and Harry had to sink low into the sidecar to avoid them.
Quote:
Harry saw the Death Eaters swerve out of sight to avoid the deadly trail of flame, and at the same time felt the sidecar sway ominously: Its metal connections to the bike had splintered with the force of acceleration.
Quote:
He did it instinctively, without any sort of plan, because he hated the sight of her walking alone into the dungeon: As the door began to swing closed, he slipped into the courtroom behind her.
Why the hell is she using colons everywhere? I'm reading this Stephen King book Cell and he used one like that somewhere as well. I tried to find that example but I couldn't >[
And on Wikipedia it says:
Quote:
As a rule, however, a colon informs the reader that what follows proves and explains, or simply enumerates elements of what is referred to before.
But then I was taught a semi-colon is to emphasize the connection, more so than a conjunction. Which does make sense here. If I had to guess on some essay that was important, I figure I would go with semi-colon in the end.
Edit: Oh wait, I just read Ouch!'s post. So, what, it's kind of up to me. Grammar pisses me off.
