1. Disarmus
   Expelliarmus
2. Finite Incantatem
   Manus Vacio

This one's used early and often in the Potter books. Harry seems to like it a lot -- he's a "defense is the best offense" kind of wizard.

1. Accio
   Engorgio
2. Expecto Patronum
   Wingardium Leviosa

This spell makes objects float in the air (note the similarity to "levitate"). Hermione masters it right away and officiously gives Ron and Harry unasked-for help with it.

1. Abracadabra!
   Whammo!
2. Presto!
   Ta da!

The name of the "killing" spell is "Avada Kedavra." In this way, J.K. Rowling took an innocent, well-known magic phrase and made it something very sinister.

1. A boggart
   A dragon
2. A hinkypunk
   A Cornish pixie

Remus Lupin teaches the third-years this trick in Defense Against the Dark Arts. It's a practice run for learning to fend off dementors.

1. Charm
   Hex
2. Incantation
   Imprecation

The negative effects need to be intended for a spell to be a hex. That is, if a spell misses its target and breaks something, it's not necessarily a hex.

1. Aqua Eructo
   Avada Kedavra
2. Cruciatus
   Imperius

Aqua Eructo makes water spout from the user's wand. This, presumably, is forgivable -- though it might take a while if the person in the way had spent a long time on their hair that morning.

1. Filius Flitwick
   Professor Binns
2. Minerva McGonagall
   Severus Snape

"Sectumsempra" is a harsh spell that causes slashes to appear on the victim's body, as though they were being cut by an invisible sword. It's appropriate, then, that it's associated with the moody, sometimes scary, Snape.

1. Alohomora
   Infidelius
2. Portis Portatis
   Finitus

"Alohomora" is put to good use by Ron, Harry and Hermione in the series. After all, they're always in places they're not supposed to be!

1. Accio
   Expecto
2. Gardo
   Voca

"Expecto" is Latin for "I await." The use of this verb suggests that the spellcaster is confident his or her patronus will appear -- and confidence seems to be important to this spell.

1. Happy
   Unhappy
2. Confused
   Excited

"Confundere" means "to confuse" in Latin, and this is the sense in which the Potter books use it. However, the English word "confound" has evolved to mean "frustrate expectations" or even "prevent."

1. Accio
   Rictumsempra
2. Renervate
   Stupefy

Naturally, it's "stupefy." In English, this means to make passive or nearly unconscious. In the Potter world, it's a useful, nonlethal defensive spell.

1. Accio
   Expecto Patronum
2. Finite Incantatem
   Reducio

Harry uses it to call his broom to him. After that, it's possible for him to outfly the fierce Hungarian Horntail dragon.

1. the Dark Mark
   the Dumbledore's Army logo
2. the Gryffindor Lion
   the Phoenix (from the Order of the Phoenix)

The "Morsmordre" spell is essentially a form of magical firework. It creates Voldemort's glowing-skull symbol in the sky. Death Eaters shoot it off when they're feeling rambunctious.

1. Cedric Diggory
   Luna Lovegood
2. Professor Quirrell
   Severus Snape

Cedric uses this spell in the Triwizard Tournament. It creates a kind of diver's helmet around his head when he is diving in the lake.

1. Blue
   Green
2. Red
   White

Harry remembers the blinding green light from his infancy. He saw it when Lord Voldemort tried to kill him and failed.

1. Accio
   Aqua Eructo
2. Oculus Reparo
   Sectumsempra

In the first film, overachiever Hermione uses this to fix Harry's glasses on the Hogwarts Express. Pretty impressive, given that she hasn't had an hour of formal instruction in magic yet!

1. Engorgio
   Imperio
2. Renervate
   Wingardium Leviosa

"Reducio" is used to come to the rescue when someone or something has been hit by the "Engorgio" spell. Although it could come in handy when packing for trips!

1. True
2. False

Though a wand is a witch or wizard's essential tool, it isn't always necessary. The students of Hogwarts learn wandless magic, and sometimes simply whisper a spell to make it happen.

1. A counter-spell
   A jinx
2. A minx
   A forgivable

Jinxes are unpleasant, but not as bad as hexes. And certainly not as bad as curses.

1. Diffindo
   Finite Incantatem
2. Reparo
   Sectumsempra

"Finite Incantatem" essentially means "Finish (the) incantation." It's useful for getting magical mayhem under control.

1. Out!
   Extingue!
2. Nox!
   Tenebrae!

"Nox" is Latin for "night." That's why it bookends "lumos," which creates a magical light for the spellcaster.

1. Squibbus
   Homunculus
2. Muggletum
   Mundanii

Of course, the answer is "muggletum," taken from J.K. Rowling's well-known word for non-witches and non-wizards. "Mundanii" would almost work -- "mundanes" is a sci-fi and fantasy lover's term for people who don't read or watch those genres.

1. Makes his or her hearing sharper
   Makes him or her taller
2. Makes him or her shorter
   Makes his or her voice louder

This one comes in handy at the Quidditch World Cup. Ludo Bagman uses it to project his voice out over the stadium, without use of a sound system. Nifty!

1. Makes the speaker more attractive
   Hoists a person into the air upside down
2. Makes bread rise
   Raises the dead

Remus Lupin remembers this one fondly in "Prisoner of Azkaban." He says that back in his Hogwarts days, there was a period where you could "hardly move for being hoisted into the air by your ankles."

1. Dance wildly
   Fall in love
2. Forget something
   Sneeze uncontrollably

This name is derived from the "tarantella," the wild, fatal dance people supposedly did after being bitten by a tarantula. (Really, people believed this!). The second half, "allegra," is a musical instruction means "quickly" in Italian.

1. Breaks or severs something
   Makes a noise louder
2. Makes a noise softer
   Makes up a bed

This word might (confusingly) remind you more of "diffident," the English word for shy, than the Latin "diffindere," for "to split." A little Latin goes a long way in the Potter world.

1. Auror
   Dementor
2. Horcrux
   Secret-Keeper

"FIdelius" is adapted from the Latin word for "faithful." This "faithful" person then protects the secrets of the spellcaster, as Peter Pettigrew did (and then didn't do) for James and Lily Potter.

1. the Dancing Curse
   the Slug-Vomiting Hex
2. the Leg-Locker Curse
   Walk of Shame

The Latin-derived name for this one makes it sound worse than it is. It sounds a bit like the victim is being forced to ambulate toward his or her death! But no, it just means the legs are stuck together. (Whew).

1. Draco Malfoy
   Severus Snape
2. Ginny Weasley
   Molly Weasley

This spell causes bats to come out of a person's nose and fly off. (Seriously!) Ginny once used it on Draco Malfoy, who probably deserved it.

1. Aire Libris
   Evanesco
2. Disapparatus
   Tenebris

You probably knew that this is closely related to the English word "evanescent," meaning "fleeting or disappearing." Ah, all becomes clear (maybe literally!)

1. Jubilo
   Felicitas
2. Esmilio
   it's just called the Cheering Charm.

While many charms, jinxes and hexes have Latin-derived names, this one is quite simple. It's said to wear off within a few hours.

1. Banshee
   Caterwauling
2. Howler
   Yowling

The correct name for this spell is the Caterwauling Charm. The adjective was probably chosen because it starts with C -- Rowling likes her alliteration.

1. Episkey
   Ferula
2. Oculus Reparo
   both #1 and #2

Oculus Reparo, if you'll remember, was the glasses-repair spell Hermione used early in the series. But "Episkey" is a catchall spell for minor injuries, while "Ferula" creates a splint for broken limbs.

1. Barty Crouch Jr.
   Severus Snape
2. Mad-Eye Moody
   Gilderoy Lockhart

Yes, this one is a bit of a trick question. It's Barty Crouch Jr, disguised as Mad-Eye, who gives the colorful lecture on the Unforgivable Curses.

1. Grindelwald
   Nicolas Flamel
2. Rowena Ravenclaw
   Wendelin the Weird

This witch only appears in a Hogwarts textbook. The book notes that true witches used the Flame-Freezing Charm to escape injury when being burnt at the stake. Wendelin is said to have enjoyed "the tickling sensation" of the flames.
