Waddiwasi (wah-di-WAH-see)
"vadd" Sw. a soft mass +
"vas y" Fr. go there
It makes sense because Lupin
didn't just make a wad of gum leave that keyhole, but directed it
into Peeves' nose.
(contributed by Alina)
Shoots a wad of gum out of a keyhole.
Lupin considers this to be a useful little spell. He used it to remove a wad of gum from a keyhole that Peeves was putting there. The gum then shot up Peeves' nose (PA7).
The "useful spell" that Lupin was showing them was undoubtedly the "wasi" part, in this case with a target word attached, "wad." Again we see how important intention is to magic, since the wad was directed into Peeves' nose by intent with the "go there" part of the spell. In another situation, the spell might be "stolawasi" to send a robe into a student's trunk, but it would only work if the student focused his mind on where he wanted the robe to go.

Harry and Ron shot sparks to hold off an advancing skrewt (GF21).
For the third task, each champion was instructed beforehand to send up red sparks if he or she got into difficulty and wished to be rescued (GF31).
When Harry's temper was getting the better of him, his wand inadvertently gave off a few red and gold sparks (OP2).
The signal that it was clear for the Advance Guard to leave Privet Drive with Harry was a shower of red sparks, then green sparks, far off in the night sky (OP3).
Harry's wand spun around by itself and shot gold flames at Voldemort when the latter pursued him after his departure from Privet Drive. Albus Dumbledore later said that this was because during their duel three years before, Harry's wand had taken on some of the power and qualities of Voldemort's wand, recognized him as both kin and mortal enemy, and regurgitated some of his own power back at him (DH4, DH5, DH35).
Harry's wand emitted a bang and red sparks when he closed the curtains over Mrs. Black's portrait (DH9).
wand writing
no incantation given
Emits an animated ribbon from the tip of the wand that spells words or forms numbers
Dumbledore used ribbon from his wand to form letters in air (PS7).
Tom Marvolo Riddle wrote his name in the air, then rearranged the letters (CS17)
The judges of the Triwizard Tournament showed scores with ribbons coming from their wands (GF20)
Wingardium Leviosa (win-GAR-dee-um lev-ee-OH-sa)
"Levitation Charm" (OP31)
"wing" + "arduus" L. high, steep + "levo" L. to raise up, levitate
Causes an object to levitate.
Very simple spell taught to first year Charms students (PS10).
In an excellent example of how intention affects magic, Ron used this spell to make a mountain troll's club levitate, then crash back onto its own head, even though the "wing" portion of the spell seems specific to feathers (PS10).
Harry cast this on the sidecar after it broke off from the flying motorbike (DH4).
Ron cast this on a twig to move it into position to press the place at the roots of the Whomping Willow to make it hold still, clearing the way to the tunnel leading to the Shrieking Shack (DH32).
wizard space
Causes objects to hold more than their outer dimensions would seem to allow.
While not mentioned by name, this magical effect is seen in a number of places in the wizarding world. It would seem that "wizard space" is fairly common, since Molly Weasley didn't seem a bit surprised when their Ford Anglia could hold a lot more people and cargo than it should (CS5).
(On the other hand, Molly Weasley knew that the car "borrowed" by Mundungus for a Christmas Day visit to Arthur Weasley in hospital had been "enlarged with a spell", rather than having been built like that (OP23).)
Cauldrons apparently can hold a lot of stuff. Harry dumped an entire collection of Lockhart's books into Ginny's cauldron, for example. And apparently it didn't get too heavy for an eleven-year-old to carry as a result (CS4).
Harry's invisibility cloak also seems to have this quality, since it can expand to cover several children and a crated dragon, but still can be easily used by a single person (PS14, etc). However, it has limits. When the D.A. was first formed, Hermione pointed out that the invisibility cloak couldn't cover all the members at the same time (OP17).
The magical tents Mr. Weasley borrowed for use at the Quidditch World Cup were considerably more spacious inside than they looked from the outside (GF7). Perkins didn't want them back because his lumbago was too bad to let him camp comfortably, so Mr. Weasley kept them until he loaned one to Hermione, which proved to be very useful (DH14). That tent was later lost during a raid by Snatchers (DH26).
