Accio (AK-ee-oh or A-see-oh)
"Summoning Charm"
"accio" L. send for, summon
Causes an object to fly to the caster, even over quite some distance; the target object is said to have been Summoned. It will even break through barriers or break chains in order to obey the summons, although this may depend on the power of the spell caster. The spell word can be combined with a target word or can be used alone with intention filling in the required information. It would seem that the caster must know at least the general location of the object Summoned.
- Mrs. Weasley used a series of Summoning Charms to find the magical items Fred and George were trying to sneak out of the house at the time of the Quidditch World Cup (GF6 - note: Book/Chapter).
- Harry learned the Summoning Charm for the first task, when he Summoned his Firebolt to him so he could fly around and past the Hungarian Horntail (GF20).
- The fake Moody used a Summoning Charm to grab the Marauder's Map off the stairs on the night Harry solved the golden egg clue (GF25).
- Harry used this charm to call the Triwizard Cup to him while escaping Voldemort and the Death Eaters (GF34).
- Used several times during the Battle of the Department of Mysteries by both sides. The most notable instances were by Death Eaters attempting to pull the prophecy sphere from Harry's hands, by Hermione to pick up wands after a Disarming Spell hit, and most memorably by Ron in the Brain Room after he'd been knocked silly (OP35).
- Harry attempted to cast this nonverbally to Summon his wand into his hand after Draco Malfoy had hit him with a Full-Body Bind, but Harry couldn't make the spell work at the time (HBP8).
- Harry used this to Summon Rosmerta's brooms so that he and Dumbledore could return quickly to the castle on the night of the Battle of the Tower (HBP27).
NOTE: The pronunciation of this spell has been debated by fans. The "official" pronunciation from Scholastic is "A-see-oh." This is the pronunciation used in the audio version of the books. The word is Latin, however, and in Latin the letter C is always pronounced 'hard,' the same as the letter K. Some languages which are descended from Latin, such as Italian, pronounce 'cc' as 'ch,' but this is almost certainly not correct.
- Harry raised his wand. "Accio Firebolt!" ... And then he heard it, speeding through the air towards him, he turned and saw his Firebolt hurtling towards him around the edge of the woods..."
- Ron Weasley: "Accio Brain!"
- "George," said Fred, "I think we've outgrown a full-time education."
"Yeah, I've been feeling that way myself," said George lightly.
"Time to test our talents in the real world, d'you reckon?" asked Fred.
"Definitely," said George.
And before Umbridge could say a word, they raised their wands and said together, "Accio Brooms!"
Harry heard a loud crash somewhere in the distance. Looking to his left he ducked just in time -- Fred and George's broomsticks, one still trailing the heavy chain and iron peg with which Umbridge had fastened them to the wall, were hurtling along the corridor toward their owners. They turned left, streaked down the stairs, and stopped sharply in front of the twins, the chain clattering loudly on the flagged stone floor.
"We won't be seeing you," Fred told Professor Umbridge, swinging his leg over his broomstick.
"Yeah, don't bother to keep in touch," said George, mounting his own.
Fred looked around at the assembled students and at the silent, watchful crowd.
"If anybody fancies buying a Portable Swamp, as demonstrated upstairs, come to number ninety-three Diagon Alley -- Weasley's Wizard Wheezes," he said in a loud voice. "Our new premises!"
"Special discounts to Hogwarts students who swear they're going to use our products to get rid of this old bat," said George, pointing at Professor Umbridge.
"STOP THEM!" shrieked Umbridge, but it was too late. As the Inquisitorial Squad closed in, Fred and George kicked off from the floor, shooting fifteen feet into the air, the iron peg swinging dangerously below. Fred looked across the hall at the poltergeist bobbing on his level above the crowd.
"Give her hell from us, Peeves."
And Peeves, whom Harry had never seen take an order from a student before, swept his belled hat from his head and sprang to a salute as Fred and George wheeled about to tumultuous applause from the students below and sped out of the open front doors into the glorious sunset.
- "Hand over the prophecy and no one needs get hurt," said Malfoy coolly.
It was Harry's turn to laugh.
"Yeah, right!" he said. "I give you this prophecy, is it? And you'll just let us skip off home, will you?"
The words were hardly out of his mouth when the female Death Eater shrieked: "Accio proph-"
Harry was just ready for her: he shouted "Protego!" before she had finished her spell, and though the glass sphere slipped to the tips of is fingers he managed to cling on to it.
