Spells - I

Impedimenta (Impediment Jinx, Impediment Curse)

Pronunciation: im-ped-ih-MEN-tah (IPA: /ɪm.ˌpɛ.dɪ.'mɛn.ta/

Description: This hex is capable of tripping, freezing, binding, knocking back and generally impeding the target's progress towards the caster. The extent to which the spell's specific action can be controlled by the caster is not made clear. If this spell does bind it does eventually wear off as stated in Deathly Hallows.
Seen/Mentioned: Used in Goblet of Fire when Harry is practicing for the third task. Also used by Madam Hooch to shortly stop Harry from fighting with Draco. Also seen toward the end of Order of the Phoenix, when Harry is fighting the Death Eaters. Stronger uses of this spell seem capable of blowing targets away.
Suggested Etymology: Latin impedimentum (plural impedimenta) meaning "a hindrance" or "an impediment".

Imperio (Imperius Curse)

Pronunciation: im-PEER-ee-oh (IPA: [ɪm.'pi.ɹi.ˌəʊ]) (classical Latin: eem-PEHR-ee-oh (IPA: [im.ˈpɛɾ.i.ˌɔ])

Description: Causes the victim of the curse to obey the spoken/unspoken commands of the caster. The experience of being controlled by this curse is described as a complete, wonderful release from any sense of responsibility or worry over one's actions, at the price of one's free will. Resisting the effect of the curse is possible, however, and several individuals have been able to successfully overcome it, including Harry and both of the Crouchs, who learn to resist the curse after being subjected to its effects for an extended period. Harry describes the feeling of being the caster as controlling a marionette through a wand (although Harry's particular experience is suspect due to his lack of commitment to casting Unforgivable Curses). One of the three Unforgivable Curses.
Seen/Mentioned: first mentioned (not by name) in the first book when Ron told Harry that Lucius Malfoy claimed himself being jinxed during the first war, thus Lucius evaded capture. First seen in Goblet of Fire introduced by Barty Crouch Jr (acting as Moody) and used on a spider. Used by Harry in Deathly Hallows on a Gringotts goblin and a Death Eater.
Suggested Etymology: Imperare is Latin for "to order, command", and is the root of several modern English words. Imperium means "command" or "domain", and imperio means (among other things) "with authority". (Compare to impero, "I command", and to crucio above.) Imperius is not, however, a Latin word.

Impervius (Impervius Charm)

Pronunciation: im-PURR-vee-uss (IPA: [ɪm.'pɝ.vi.ˌɛs])

Description: This spell makes something repel (literally, become impervious to) substances and outside forces, including water.

Suggested Etymology: Latin incendo meaning "to set fire"

Description: Causes objects to swell in size.

Then seen in Goblet of Fire when Barty Crouch Jr, impersonating Moody, casts it on a spider to enhance a demonstration of the effects of the Cruciatus Curse, and Ron suggested it might be the cause of Hagrid's abnormal size before learning that he is half-giant. Harry in Deathly Hallows also cast it on a spider.
Suggested Etymology: English word engorge meaning "to fill to excess".

Description: Used to heal relatively minor injuries. When this spell is cast, the person feels their injured body part go very hot and then very cold.

Notes: Rowling writes in Half-Blood Prince that Harry's knowledge tells him this spell could belong to a family (or variety) of Healing Spells.

Evanesco (Vanishing Spell)

Pronunciation: ev-an-ES-koh (IPA: (IPA: /ɛ.vn̩.'ɛs.kəʊ/)
Description: Makes the target vanish.
Seen/Mentioned: Used in Order of the Phoenix by Snape to make Harry's potions disappear from his cauldron. In addition, when Fred and George were showing off their puking pastilles, Lee Jordan cleared the bucket of vomit with the Evanesco spell. During their stay at #12, Grimmauld Place, Bill uses this on a stack of documents. This suggests that Vanished objects can be recovered.
Suggested Etymology: Latin evanesco meaning "to vanish".[13]
Notes: According to Minerva McGonagall, in Deathly Hallows, Vanished objects and organisms go "into non-being, which is to say, everything." This was McGonagall's response to the question, "Where do Vanished objects go?" from the doorknocker at Ravenclaw Tower.

Expecto Patronum (Patronus Charm)

Pronunciation: ex-PEK-toh pa-TROH-num

Description: Conjures an incarnation of the caster's innermost positive feelings, such as joy, hope, or the desire to survive, known as a Patronus. A Patronus is conjured as a protector, and is a weapon rather than a predator of souls: Patronuses shield their conjurors from Dementors, and can even drive them away. A Patronus "cannot feel despair, as real humans can, so Dementors can't hurt it."[16] The conjured Patronus protects the witch or wizard that summoned it, obeys his or her commands, and fades away shortly after it is no longer required. When conjured, a Patronus appears silvery, ethereal, and semi-transparent. Improperly formed Patronuses range from momentary formless bursts of silvery mist, to poorly-defined forms which are easily defeated or quickly dissipate on their own. A full-fledged (or corporeal) Patronus takes on a fixed animal form that is often significant to the witch or wizard casting the charm. Patronuses summoned by a particular person have been known to change, such as Tonks' patronus. Rowling has said that Snape was the only Death Eater to be able to produce a Patronus. According to her this is 'because a Patronus is used against things that the Death Eaters generally generate, or fight alongside. They would not need Patronuses'.[17] According to Fantastic Beasts and Where to Find Them, the Charm is also the only known defensive spell against Lethifolds.
Seen/Mentioned: First seen in Prisoner of Azkaban when a Dementor appears in the Hogwarts Express, and Hermione says that Remus Lupin repelled the Dementor by casting a silvery object from his wand. Harry's corporeal Patronus first appears when Draco Malfoy & his friends dress up as Dementors in an attempt to sabotage Harry, he decides to ask Lupin to teach him how to defend himself against the dementors and takes classes where a boggart takes the form of a dementor. He then uses it again towards the end of the book while trying to repel hundreds of Dementors from Sirius and himself.
Notes: Dumbledore has devised a method of using Patronuses to deliver messages putting it into the exclusive use of the Order of the Phoenix. Members of the Order are the only wizards who know how to use their spirit guardians to send messages to one another. According to Rowling, the Patronus is "an immensely efficient messenger" as it is not hindered by physical obstructions or dark matters. Each Patronus has a special quality and appearance that is different and easy to recognise, which makes it clear which Order member has sent the message. In addition, since no one can conjure another person's Patronus, this method of communication does not carry the risk of passing fake messages.[18] It is noteworthy that in Deathly Hallows, McGonagall creates three Patronuses simultaneously to summon Professors Flitwick, Sprout, and Slughorn.
Suggested Etymology: Expecto Patronum is Latin for "I await a protector".[19] It is related to "pater" (father) and Harry's Patronus indeed takes the same form as that of his father's (a stag).

Expelliarmus (Disarming Charm, Disarming Spell)

Pronunciation: ex-pel-ee-AR-mus (IPA: /ɛks.ˌpɛ.li.'a˞.mɪs/)

Description: This spell is used to disarm another wizard, typically by causing the victim's wand to fly out of reach[20][21]. It can also throw the target backwards when enough power is put into it. As demonstrated in Prisoner of Azkaban, simultaneous use of this spell by multiple witches or wizards on a single person can throw the wizard back with much greater force.
Seen/Mentioned: First seen in Chamber of Secrets, when Snape disarms Gilderoy Lockhart in the Duelling Club; from then on it is commonly used throughout the rest of the series. Draco uses it to disarm Dumbledore and Harry uses the spell to not only disarm Gregory Goyle in the Room of Requirement, but also to reflect Voldemort's killing curse during the final battle. It is seen by the Death Eaters as Harry's signature spell, as he had used it to duel Voldemort in both Goblet of Fire and Deathly Hallows.
Suggested Etymology: Latin expello meaning "to expel, to thrust away" and Latin arma meaning "weapons of war".

Expulso

Pronunciation: ecks-PUL-soh (IPA: /ɛks.ˈpʊl.səʊ/)

Confringo (Blasting Curse)

Description: Causes anything that the spell meets to explode.
Seen/Mentioned: Seen only in Deathly Hallows. In the opening chapters, it is cast by Harry to destroy the sidecar of the flying motorbike.[DH Ch.4] Later, it is used by Hermione in an attempt to kill Nagini and facilitate an escape from Bathilda Bagshot's house in Godric's Hollow.[DH Ch.17]

Crucio (Cruciatus Curse)

Pronunciation: KROO-see-oh/KROO-shee-OH (IPA: /ˈkɹu.si.əʊ/)

Description: Inflicts unbearable pain on the recipient of the curse. The effects of the curse depend upon the desires and emotions of the character - to produce the "excruciating" pain implied by the name, one must (according to Bellatrix Lestrange) desire to cause pain purely for its own sake. The extreme pain inflicted by the curse when cast so - without any apparent evidence of physical harm - makes it uniquely suited as a form of torture. One of the three Unforgivable Curses.
Seen/Mentioned: first seen in Goblet of Fire introduced by Barty Crouch Jr (acting as Moody) and used on a spider. Used regularly by the Death Eaters as torture, and by Voldemort as punishment, even against his servants. Used twice by Harry on Death Eaters.
Suggested Etymology: Crucio (Latin) means "I torture" originating from crux (genitive crucis), which means "torture platform or stake" or, more specifically "cross". The word excruciating is descended from the same root - crucifixion was a form of torturous execution. In the novels, the verbal form of the word is 'cruciate', as when Amycus Carrow says in the final book "I’ll Cruciate the lot of ’em."

Spells - A

Accio (Summoning Charm)

Pronunciation: Various suggestions have been made, including:

Also seen in Half-Blood Prince and Deathly Hallows to try to summon Horcruxes, and Harry even tries to summon a falling Rubeus Hagrid.
Suggested Etymology: The Latin word accio means "I call" or "I summon".[3]In the Hungarian translation, the spell is called "Invito", possibly from the word "to invite".

Later unsuccessfully cast by Ron, on the door from the room with the winged keys in Hogwarts.[PS Ch.16] Loses use gradually in the series as the characters discover more and more doors, chests etc. with counter-charms on them (e.g. The doors into Professor Snape's and Professor Umbridge's offices are mentioned as being Alohomora-proof.)
Etymology: From the West African Sidiki dialect used in geomancy meaning: Friendly to thieves as stated by J.K. Rowling in testimony during the WB and JKR vs. RDR Books

Avada Kedavra (Killing Curse)

Pronunciation: ah-VAH-dah kuh-DAHV-rah (IPA: /ə.'væ.də kə.'dæv.ɹə/)

Description: causes a bright green flash and a rushing noise; the curse causes instant death to the victim. There is no known counter-curse or blocking spell (with the exception of the curse striking another spell midflight, negating both), although the caster can be interrupted, the victim can dodge the green jet, hide behind solid objects (which burst into flame when hit by it), or, if the casting wizard is not sufficiently competent, the curse may be completely ineffective as described by Barty Crouch Jr (acting as Alastor Moody) in Goblet of Fire. Harry twice countered this spell by casting Expelliarmus. It is one of the three Unforgivable Curses; the use of this spell on another human being renders a life sentence in Azkaban.
The magical conditions have also been documented to defeat the curse, even on a direct hit:

* Harry Potter was given magical protection against Lord Voldemort's use of the curse, when his mother sacrificed herself to save him.
* Harry is saved by the twin cores effect between his wand and Voldemort's during a duel, as well as during a battle. During this battle, Harry's phoenix feather wand snaps the wand Voldemort borrowed from one of his servants, Lucius Malfoy. The reason for this is unknown. Dumbledore believes this feat to be due to the unique connections and relationships between the two duellists, which are complex and are "realms of magic hitherto unknown".
* In Deathly Hallows, Harry is saved twice. The first time because when Voldemort tried to kill Harry as a baby, a piece of Voldemort's soul flaked off and was trapped within Harry himself (giving Harry a connection to, and many of the powers of, Voldemort). When the killing curse hit Harry in the Forbidden Forest, it killed the piece of Voldemort's soul trapped in Harry, and sent Harry to a nether region where Voldemort's use of Harry's blood gave Harry a lifeline back to the world of the living, should he choose to use it, and he decided to return to life. The second time, Harry was able to deflect the curse back at Voldemort (who died from it) because of a special condition involving the Elder Wand. This had been 'won' by Draco when he disarmed Dumbledore of his wand, but none understood this at the time, and Draco did not use the Elder Wand. Harry had won Draco's wand in a life-or-death duel, thereby proving to the Elder Wand that Harry should be the wand's true master. Therefore, when Harry used Draco's wand to cast Expelliarmus against Voldemort's killing curse, the killing curse rebounded on Voldemort leaving Harry unharmed.

Seen/Mentioned: First said (not by name) at the beginning of the first book when Harry arrives to the Dursley's home. First seen in Goblet of Fire against Muggle Frank Bryce, and in every book following.
Suggested Etymology: During an audience interview at the Edinburgh Book Festival (15 April 2004) Rowling said: "Does anyone know where avada kedavra came from? It is an ancient spell in Aramaic, and it is the original of abracadabra, which means 'let the thing be destroyed.' Originally, it was used to cure illness and the 'thing' was the illness, but I decided to make it the 'thing' as in the person standing in front of me. I take a lot of liberties with things like that. I twist them round and make them mine."

Avis

Pronunciation: AH-vis (IPA: /a'vɪs/)

Description: This charm creates a flock of birds that pour forth from the caster's wand. When coupled with Oppugno, it can be used offensively.
Seen/Mentioned: Shown in Goblet of Fire, cast by Mr Ollivander to test Viktor Krum's wand.[GF Ch.18] In Half-blood Prince, it is cast by Hermione, followed by Oppugno which causes the birds to attack Ron Weasley.[HBP Ch.14]
Suggested Etymology: The Latin word avis which means, "bird"
