Dumbledore: Dear Mr. Potter, you have been accepted to Hogwarts School of Witchcraft and Wizardry. Soon, you and your schoolmates will join us here, and your education in the magical arts will begin.

~

Hermione: Now, if you two don't mind, I'm going to bed before either of you comes up with another clever idea to get us killed. Or worse, expelled.
Ron: She needs to sort out her priorities.

~

Hagrid: I shouldn't have told you that

~

Dumbledore: Don't spend your life in dreams, Harry, and forget to live.

~

[In the Devil's Snare]
Hermione: I've read about these! They'll kill you faster if you don't relax!
Ron: Faster? Oh, now I can relax!
[After Hermione and Harry sink in the Devil's Snare, Ron is still panicking]
Harry: He's not relaxing!
Hermione: I remember reading about this in Herbology. 'Devil's Snare can be deadly fun, but will sulk in the sun' that's it! It hates sunlight!
[She exerts a type of sunlight from her wand, after muttering a charm. Ron falls to the ground below.]
Ron: (sigh) Lucky thing we didn't panic.

~

Hagrid: You're a wizard, Harry!
Harry: I'm a what?

~

Dumbledore: What happened between you and Professor Quirrell is a complete secret, so naturally, the whole school knows.

~

Dumbledore: Alas, earwax!

~

Ron: Wingardium leviosa!
Hermione: Stop, stop stop! You're going to take someone's eye out. Besides, you're saying it wrong. It's levi-O-sa, not levio-sa!

~

Ron: You're a little scary sometimes, you know that. Brilliant. But scary.

~

Hagrid: Dry up Dursley, you old prune!

~

Percy Weasley: And watch the staircases. They like to change.

~

Ron: It's scary! She knows more about you than you do!
Harry: Doesn't everybody?

~

George Weasly: He's not Fred, I am.
Fred Weasly: Honestly woman, you call yourself our mother.

~

Seamus Finnigan: I'm half and half. Dad's a muggle, mum's a witch; bit of a nasty shock when he found out.

~

Draco Malfoy: So it's true then, what they were saying on the train. Harry Potter has come to Hogwarts.

~

Caretaker Argus Filch: Detention would find you hanging by your thumbs in the dungeons...God, I miss the screamin'...

~

Oliver Wood: Scared, Potter?
Harry: A little.
Oliver Wood: I was, too, at my first match.
Harry: What happened?
Oliver Wood: I can't really remember. Took a bludger to the head two minutes
in. Ended up in the hospital a week later.

~

Dudley Dursley: Daddy's gone mad hasn't he?

~

Professor McGonagall: This boy will be famous. There won't be a child in our world who doesn't know his name.

~

Harry: I can't be a wizard. I'm just Harry, just Harry.

~

Mr. Ollivander: It's curious that you should be destined for this wand when it's brother gave you that scar.

~

Ron: Wicked

~

Snape: I can teach you how to bewitch the mind, and ensnare the senses. I can teach you how to bottle fame, brew glory, and even put a stopper on death.

~

Neville Longbottom: The only problem is I can't remember what I've forgotten.

~

Ron: I think we've had a bad influence on her.

~

Ron: It's you that has to go on. Not me. Not Hermione. You!

~

Dumbledore: It takes a great deal of bravery to stand up to your enemies but a great deal more to stand up to your friends.

~

Dumbledore: It was one of my more brilliant ideas. And between you and me, that is saying something.

~

Dumbledore: And finally, I must tell you that this year, the third-floor corridor on the right-hand side is out of bounds to everyone who does not wish to die a very painful death.

~

Ron: That was bloody brilliant!
Professor McGonagall: Well, thank you for that assessment, Mr.Weasley.

~

Ron: What do they think they're doing, keeping a thing like that locked up in a school?!
Hermione: You don't use your eyes, do you? Didn't you see what it was standing on?
Ron: I wasn't looking at its feet!! I was a bit preoccupied with its heads...or
maybe you didn't notice? There were three!!

~

[Looking at a recently hatched dragon]
Hagrid: Isn't he beautiful? Oh, bless him! Look! He knows his mummy! 'alo Norbert!
Harry: Norbert?
Hagrid: Yeah, well, he's gotta have a name, don't he?

~

Ron: Immortal?
Hermione: It means you'll never die.
Ron: (angry, loudly) I know what it means!

~

Ron: Mental that one, I'm telling you.

~

Harry: [On how Hagrid is refusing to say Voldemort's name] Perhaps if you wrote it down...
Hagrid: Nah. Can't spell it.

~

[About the Bludgers]
Oliver Wood: Nasty little buggers.

~

Hagrid: Not all wizards are good.
