1. Something would levitate.
   Your friend would turn green.
2. It would start to rain.
   Your toenails would grow longer.

In the first "Harry Potter" book, Hermione lectures Ron on the correct pronunciation of this spell. Then she shows everyone in Charms class exactly how it's done, levitating a feather.

1. The Multiplying Spell
   The Invisibility Charm
2. The Killing Curse
   The Hiccups Hex

The Killing Curse is one of the three Unforgivable Curses because it causes instantaneous death for its target. Using this curse earns the witch or wizard a one-way ticket to Azkaban Prison!

1. A Boggart
   A dragon
2. A Pensieve
   A Patronus

The Patronus Charm protects witches and wizards from soul-sucking Dementors. A Patronus is a glowing guardian in the form of an animal. Harry's, for instance, is a stag, like his father's.

1. Kills
   Tortures
2. Puts to sleep
   Wipes the memory

The Cruciatus Curse causes its target severe pain, which is why it's forbidden by the Ministry of Magic. It's also one of the curses favored by Voldemort and his Death Eaters, the baddies.

1. Impervius
   Stupefy
2. Expelliarmus
   Locomotor

Shouting "Expelliarmus" will cause your opponent's wand to fly out of their hand. It's a popular spell in duels and can even disarm more than one person at once if they're standing close together.

1. Alohomora
   Confringo
2. Descendo
   Morsmordre

This simple Unlocking Spell is also called the Thief's Friend because it allows the user to discreetly open a locked door. However, a person can bewitch a door to keep "Alohomora" from working.

1. A magic wand
   A Philosopher's Stone
2. A flying broom
   A Portkey

By using the "Portus" spell, a witch or wizard can turn any ordinary object into a Portkey. Touching a Portkey transports a person to a specific location, but involves some discomfort.

1. Pain
   Tickling sensation
2. Sleepiness
   Confusion

The Tickling Charm sounds harmless, but if you've ever been tickled mercilessly, you know that it's no joke (even if you're laughing uncontrollably). Harry uses this spell on Draco in a duel.

1. Riddikulus
   Avenseguim
2. Protego Diabolica
   Revelio

A Boggart appears in the form of whatever you fear most, but disappears when you laugh. The "Riddikulus" spell turns the Boggart into something silly, which helps you defeat it with your chuckles.

1. Elongates it
   Repairs it
2. Turns out its light
   Reduces its power

Wands are like smartphones in the sense that they function as a handy-dandy flashlight. But if you want to extinguish the light at the end of the wand, all you have to say is "Nox."

1. Transforms them
   Frightens them
2. Transports them
   Stuns them

The Stunning Spell is a useful curse if you want to temporarily disable someone but not harm them. Harry himself refers to it as a "wizard's bread and butter" in the "Order of the Phoenix" film.

1. Liberacorpus
   Muffliato
2. Aberto
   Obliviate

Severus Snape created this charm as a student, and it's certainly a handy one for students who don't want to be overheard talking by the professor! All other people will hear is a strange buzzing sound.

1. Fix eyeglasses
   Produce money
2. Mend socks
   Remove fleas

In the first Harry Potter film, Hermione repairs Harry's glasses with this charm, showing herself to already be a skilled witch. "Reparo" is a general mending charm to fix anything.

1. Oscausi
   Tergeo
2. Engorgio
   Accio

We can think of so many situations where the Summoning Charm would be perfect. You'd never have to get up for snacks while watching TV again! Harry learns it in his fourth year at Hogwarts.

1. Dancing Feet Spell
   Spider Attack Spell
2. Teeth Cleaning Spell
   Earwax Removal Spell

The spell's name is inspired by the Tarantella, an Italian dance. The Dancing Feet Spell makes a person have uncontrollable leg spasms. The result is it looks like they're dancing!

1. Confetti
   Water
2. Fire
   Electricity

Anytime a witch or wizard needs clean drinking water, they can simply use the "Aguamenti" spell with their wand. This spell can also be used to fight fires — unless it's Fiendfyre, of course.

1. Ferula
   Tentaclifors
2. Episkey
   Defodio

"Episkey" is a healing charm that works on minor injuries. For instance, after Draco smashes Harry's nose on the Hogwarts Express in "The Half-Blood Prince," Tonks fixes it with "Episkey."

1. Teeth
   Ears
2. Nose
   Legs

Hermione gets hit with this hex accidentally, and her already prominent front teeth start growing down to her chin. Luckily Madam Pomfrey is able to fix them. Who needs orthodontia at Hogwarts?

1. Speak a different language
   Travel at light speed
2. Detect nearby people
   Jump 50 feet

Dumbledore can use a nonverbal version of this spell to tell when someone's hidden under an Invisibility Cloak (Hello, Harry). It works on people, but apparently not on elves or goblins.

1. Starts a fire
   Gathers wood
2. Lures fish
   Pitches a tent

"Incendio" is a Fire-Making Spell, akin to Muggles' lighters or matches. It's a basic spell taught to First Years at Hogwarts, and wizards and witches use it regularly, such as to light the fireplace.

1. Reducto
   Ventus
2. Petrificus Totalus
   Bombarda Maxima

To save the Philosopher's Stone, Hermione uses the Full Body-Bind Curse on her friend Neville. Poor Longbottom! At least Dumbledore acknowledges his courage at the House Cup ceremony.

1. Remove pixies
   Heal broken bones
2. Make a quill write on its own
   Defeat a Basilisk

Poor Harry needed Skele-Gro after incompetent Professor Lockhart made his arm bones disappear with a botched "Brackium Emendo" healing spell. Best to leave the spell to Madam Pomfrey, the school nurse!

1. Magnifies their voice
   Improves their memory
2. Gives them wings
   Quenches their thirst

Megaphones aren't necessary in the wizarding world! The Amplifying Charm works perfectly at raucous, celebratory events, like the Quidditch World Cup and the Triwizard Tournament.

1. A ferret
   A werewolf
2. A snake
   A mermaid

The Latin word for serpent is "serpens." Draco uses this spell while dueling Harry in "Chamber of Secrets," and Harry unwittingly reveals that he's a Parselmouth — someone who can speak to snakes!

1. They'd burp up slugs.
   You could read their mind.
2. They'd turn into a teacup.
   You'd erase their memories.

A witch or wizard can use the Memory Charm to remove specific memories in a target's mind. They frequently use "Obliviate" on Muggles to keep non-magical people in the dark about the magical world.

1. A person's greatest weakness
   A lost item
2. A person's last-used spell
   A secret

Using the Reverse Spell reveals what spell a wand last performed. For instance, in "Goblet of Fire," Voldemort's wand reveals ghostly images of the people he had recently killed. Poor Cedric!

1. Drop what they're holding
   Sing
2. Stop talking
   Stand on their head

"Relashio" is the Revulsion Jinx, which forces someone to let go of whatever they're holding. During the Triwizard Tournament, Harry uses this spell when a Grindylow has his ankle in its grasp.

1. Takes away a wizard's powers
   Makes a person unrecognizable
2. Removes a person's free will
   Transforms someone into a fish

As the Defense Against the Dark Arts teacher, Mad-Eye Moody demonstrates the Imperius Curse with a spider. Little did the students know that their teacher was a Death Eater in disguise!

1. Levicorpus
   Protego
2. Obscuro
   Vera Verto

The "Levicorpus" spell works as if some invisible force pulls a person up by their ankles and dangles them upside down. This is one of the creative jinxes that Snape invented as a student.

1. Vermiculus
   Mobiliarbus
2. Lumos
   Rennervate

"Lumos" lights up the tip of the user's wand. Harry makes good use of this spell when he has to follow the spiders into the Forbidden Forest, where he meets Hagrid's, erm, friend Aragog.

1. Drawing their wand
   Running away
2. Jinxing you
   Speaking coherently

Also known as the Tongue-Tying Curse, "Mimblewimble" is helpful when you need to prevent someone from speaking or, say, casting a spell. It literally causes the target's tongue to curl backward.

1. Scourgify
   Nebulus
2. Finite
   Mutatio Skullus

The Scouring Charm would undoubtedly come in handy when cleaning the litter box or tackling a tower of dirty dishes. Some people even use it to "clean out" a person's mouth when they curse.

1. Nightmares
   A headache
2. A runny nose
   Hiccups

Professor Quirrell mentions this curse to his students, although it's hard to imagine it having any practical educational purpose! The Curse of the Bogies gives the victim a bad cold.

1. By cushioning you
   By making you bounce
2. By slowing your fall
   By filling you with helium

Hermione uses this spell in "The Deathly Hallows" to save herself, Harry and Ron when they fall out of a cart within Gringotts Wizarding Bank. We'll take this spell over a bed sheet parachute!

1. Illegibilus
   Locomotor Wibbly
2. Glacius
   Entomorphis

This spell turns the target's legs to jelly (figuratively), making them flop to the floor. At Hogwarts, where there are a lot of student rivalries, it's easy to imagine this curse being popular!

1. Shrink it
   Make it explode
2. Duplicate it
   Magnify it

The Doubling Charm can make an exact copy of something, but the spell can be used for nefarious purposes too. In a Gringotts vault, the trio are almost killed by rapidly duplicating goblets.

1. Alarte Ascendare
   Waddiwasi
2. Calvorio
   Deletrius

In "The Prisoner of Azkaban," Professor Lupin uses this spell on Peeves, the obnoxious poltergeist who tragically didn't make it into the films. The jinx turns small, soft objects into missiles.

1. They'd have a sneezing fit.
   Their hair would fall out.
2. They'd giggle uncontrollably.
   Their shoes would stick to the floor.

If Hogwarts had physical education classes, the students might use the Stickfast Hex to cheat in foot races! It's too bad the school doesn't have a wizarding equivalent of gym class.

1. Confundo
   Surgito
2. Sectumsempra
   Revelio

In "Half-Blood Prince," Hermione uses this spell on Cormac to give Ron an edge in Quidditch tryouts. This is one of the few times we see her using magic unethically, showing her feelings for Ron.

1. Diminuendo
   Depulso
2. Dissendium
   Duro

The students practice this charm with cushions, but Neville, naturally, has a bit of trouble with the spell. He even banishes Professor Flitwick by accident! "Depulso" is the opposite of "Accio."
