Seen/Mentioned: Seen in 1994 when Barty Crouch Jr., impersonatingProfessor Moody, cast it on a spider to enhance a demonstration of the effects of the Cruciatus Curse. Rubeus Hagrid is also suspected of having performed the charm on his pumpkins once, and Ron Weasley suggested it might be the cause of Hagrid's abnormal size before learning that he is half-giant. Also used on a spider by Harry in 1998, partly to test his stolen wand, and partly to annoy Ron.
Etymology: The English word engorged means "distended" or "swollen". Almost certainly the same as the "Growth Charm" which was briefly mentioned in one of the books.
Notes: There is a difference between engorging something and enlarging it. Engorgement refers to swelling up, while simple enlargement refers to a scaled (proportionate) increase in size. However, take note that the pronunciation shares a root with engorgement.
Description:Engorgio Skullus is a Hex. This spell is used to swell the victim's skull. This may be a variation of the Engorgement Charm, as the first word of its incantation is the same.
Etymology: "Entomorphis" most possibly derives from the Greek word "έντομο" (entomo) which means "insect" and the Greek word "μορφή" (morphi) which means "form."
Notes: This may have been the spell that Harry Potter contemplating using on Dudley Dursley in 1995 "by striking him dumb, grow feelers, and have him scuttle home" when the latter was mocking Harry's nightmares about Cedric Diggory's death.
Etymology: The word comes from the Greek "episkeui" ("επισκευή"), which means "repair".
Notes: J. K. Rowling writes in Harry Potter and the Half-Blood Prince that Harry's knowledge tells him this spell could belong to a family (or variety) of Healing Spells, in the same way a species of plants belongs to a larger genus.
Seen/Mentioned: Used in 1995 by Severus 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.
Etymology: Comes from "evanescence", something that is fleeting or disappears, and the Latin evanesco, "disappear".
Notes: In 1998, when asked by the door knocker to Ravenclaw Tower "Where to vanished objects go?", Professor McGonagall replied "Into non-being, which is to say, everything." This is, so far, the best description available for what happens to Vanished objects.
Description: Has the same properties of the Hurling Hex. The use of the Latin word 'Everte' backs this up as it basically means 'to throw out'. Also, in its use by Draco Malfoy in the Duelling Club in 1992, the spell throws Harry backwards.
Description: The Patronus Charm is a defensive spell used to conjure an incarnation of the Witch's or Wizard's innermost positive emotions to act as a protector against dementors and lethifolds. It can also be used to send messages.
Etymology:Patronus means "protector" or "guardian" in Latin, reflecting the role the Patronus Charm plays. In archaic Latin, it meant "father", which is interesting, considering that Harry Potter's Patronus is the same as his father's Patronus and Animagus form. The Latin word exspecto orexpecto means "I watch for" or "I await", thus the charm's incantation roughly translates into "I await a protector".[5]
Notes: All Patronuses take the form something important to the caster, usually some animal special to them. For instance, Harry Potter's Patronus is a stag; Harry's father, James, was an Animagus whose animal form was a stag. The form of one's Patronus can change when the caster has undergone a period of heightened emotion, such as severe stress or love, such as when Nymphadora Tonks' Patronus changed to a werewolf.
Description: This spell is used to disarm another wizard, typically by causing the victim's wand to fly out of reach. It can also throw the target backwards when enough power is put into it. As demonstrated in 1994, 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 1992, when Severus Snape disarmedGilderoy Lockhart at the Duelling Club. The most notable uses of it are when Draco Malfoy used it to disarm Albus Dumbledore, and Harry used it in the final battle against Voldemort wielding the Elder Wand. It was seen by the Death Eaters as Harry's signature spell.
Etymology: Possibly a combined form of the Latin expello, "expel", and arma, "weapons" or "tools"; thus, "expel the weapon". Expellamus means "let us expel".
Note: Called Harry's "signature move" in 1997, and also used in a Doctor Who episode.
Description: This spell has only been cast once, and that was by Cho Chang in Harry Potter and the Order of the Phoenix, as an accidental curse used against her friend Marietta. It is possible that this curse can only be cast when the caster is distracted. It manifests as a jet of red light, and cause the targets clothing to spontaneously combust.
Description: A very powerful curse which causes a large explosion. Similar to the Blasting Curse, which also causes its target to explode, though the Blasting Curse seems to use heat (like a bomb) while Expulso seems to cause an explosion using pressure as opposed to heat.
Seen/Mentioned: Used by the Death EaterAntonin Dolohov in an attempt to capture Harry in 1997; this may have been the spell that caused a segment of wall to fall and kill Fred Weasley.
Etymology:Expulsum is past participle of Expellere, Latin for "to expel".
Etymomlogy: Latin "fiant", meaning "become" and "duri", nominative masculine plural of dūrus", meaning "hard" or "unyielding"; altogether the incantation reads "become hard".
Description: This complex charm enables secret information to be hidden within the soul of the recipient, known as a Secret-Keeper. The information is then irretrievable until and unless the Secret-Keeper chooses to reveal it; not even those who have the Secret revealed to them can reveal it to others. If a Secret-Keeper dies, each individual who knew of the secret in turn becomes Secret-Keeper.
Seen/Mentioned: In 1993, it was explained that when Harry was an infant, he and his parents, James and Lily Potter, were hidden from Lord Voldemort by this charm. Later, in 1995, the charm was used to hide the location of the headquarters for the Order of the Phoenix. It was also used in 1998, in which it was used to protect the location of Shell Cottage.
Etymology: Latin fidelis, which means "faithful" or "loyal".
Notes: J. K. Rowling previously stated that when a Secret-Keeper dies, the Secret they held can never be revealed to anyone else; the people who were told before the Secret-Keeper's death will still know the secret, but after the death of the Secret-Keeper no one new can be brought into the circle of knowledge (meaning that eventually all knowledge of the secret will be lost and it will become undiscoverable.[7] However, in 1997, it is clearly explained that upon the Keeper's death (specifically, Dumbledore as Keeper of 12 Grimmauld Place), all those who had been told the secret became Secret-Keepers in turn, and could pass the secret on to others. Hermione accidentally "revealed" Grimmauld Place to the Death Eater Yaxley by allowing him toApparate with her to its front doorstep. Although Yaxley would not be able to reveal the secret to other Death Eaters, he could have brought them inside by the same process. What those other Death Eaters would see and experience upon entering the house in this fashion is not fully explained. It is also not known what would happen if a secret was not passed on to anybody before the death of the Secret Keeper, although the secret information would remain as it was the moment of the Secret Keeper's death.
Notes (2): The Fidelius Charm seems to have no effect with regard to animals, as Hedwig found Ron andHermione in the headquarters of the Order of the Phoenix in 1995 (unless she was told by Dumbledore somehow). Another oddity is that the Potter's house in Godric's Hollow was apparently visible to all non-Muggles, even though the Secret should have only been known to James, Lily, Harry, Sirius, Peter, Bathilda Bagshot and Voldemort; it apparently ceased to operate upon the Potters' death.
Notes (3): In 1981 Hagrid managed to get Harry before all the Muggles could take a look at the scene. This would mean that after either killing the Potters or the destruction of their House by the Avada Kedavra curse, the spell ceased to function. Later, it would seem that the house was made to be anti-Muggle by wizards in order to pay tribute to the Potters.
Notes (4): In 1997, even though the name of Voldemort had been cursed so act as a sort of beacon as to who spoke the name and as a jinx to disarm all enchantments that it was unable to deactivate the Fidelius charms defences, however it still may have been a beacon as Death Eaters were staking out the location after Voldemort's name had been spoken within. However it seems as though the Death Eaters were there simply in case Harry showed up as they only stationed 2 Death Eaters in a rotation as though they were staking it out and did not know for sure that Harry, Hermione, and Ron were inside.
Notes (5): Those who have been informed of the secret by the Secret-Keeper are unable to tell the secret to those who are unaware of it. This is proven when Snape told Bellatrix that he couldn't speak the name of 12 Grimmauld Place. Those who do know the secret can apparently discuss it with impunity, though, as Harry and his friends spoke of Grimmauld Place in idle conversation.
Description: Fiendfyre is seemingly unstoppable cursed fire whose flames take the shape of fantastic creatures that appear to stalk those caught in its path. It can also destroy Horcruxes.
Seen/Mentioned: Possibly in the Half Blood Prince(film) when by Bellatrix and Fenirir Greyback when they attacked the Burrow at Christmas and in the order of the phoenix (film) when Albus and Voldemort duel in the ministry. Another usage was in the Deathly hallows in theBattle of Hogwarts when Crabbe, Goyle, and Draco Malfoy cornered Harry Potter in the Room of Requirement when he was searching for Rowena Ravenclaw's lost diadem. Crabbe cast Fiendfyre, which become flaming beasts that pursued Harry, Ron, and Hermione and gleefully devoured every object within the Room, including Crabbe and the Horcrux within the diadem.
Etymology: A "fiend" is a cruel or wicked person, or a demon; "fyre" is a reference to fire.
Notes: The caster must be able to control Fiendfyre, or it can spread indefinitely. The fire cannot be extinguished by water or fire-stopping charms, and the spell's flames may have some independent consciousness. Hermione Granger notes that she was aware that Fiendfyre was extremely destructive and that it can potentially destroy a Horcrux. However, she never considered using it because it was too dangerous. It is likely that Fiendfyre is too difficult or impossible for most to control.
Description: Negates spells or the effects of spells.
Seen/Mentioned:Severus Snape used it in 1992 to restore order in the Duelling Club when Harry and Draco were duelling.Remus Lupin used the short form "Finite" in 1995. In 1996, Luna used this spell to deactivate the Full body-bind curse on Harry. Harry used Finite to counter Crabbe's Descendo attack on Ron in 1998.
Etymology: Latin finire, "to finish": "finite" is the plural imperative form, so it translates to the command, "[all of you] end". Incantatem is apparently intended to recall "incantation"; the Latin verb form incantatum would mean "someone or something enspelled".
Description: A spell that conjures a ring of fire. The caster is able to control the movement and direction of the flames with enough precision to strike specific targets. The spellPartis Temporus can create a gap in the flames to allow safe passage through.
Description: With this spell, the caster's wand can leave fiery marks.
Seen/Mentioned: Two appearances, by Hermione. She used the spell to identify doors of the Department of Mysteries which members ofDumbledore's Army had already opened, by marking an "X" on them. Also used by Tom Riddle in the Chamber of Secrets to draw his name in the air with Harry's Wand.
Etymology: The incantation comes from the Latin noun flagrate, meaning "a burn".
Description: Causes fire to become harmless to those caught in it, creating only a gentle, tickling sensation instead of burns.
Seen/Mentioned: Mentioned in 1993 as used by witches and wizards during medieval burnings. Apparently, one witch (Wendelin the Weird) was so fond of the tickling sensation, she allowed herself to be caught and subsequently burned no fewer than 47 times.
Notes: This may have been the spell used by Albus Dumbledore in 1938 to seemingly set fire to Tom Riddle's old wardrobe whilst causing no physical damage. It may also be the protection in the Floo network, as well as how people communicate through fireplaces.
Description: Apparently the spell cast on broomsticks to make them fly.
Seen/Mentioned: Draco Malfoy mentioned this spell when tauntingly asking Ron Weasley why would anyone cast a Flying Charm on Ron's broomstick, which he deems a "mouldy old log", in 1995 during Ron's first Quidditch practice.
Description: This spell causes fur to grow on someone.
Seen/Mentioned:Fred and George Weasley used this spell on themselves to grow fur (along with boils), in an attempt to cheer up their sister, Ginny Weasley during the time when the Basilisk was petrifying people.
Description: Creates a duplicate of any object cast upon.
Seen/Mentioned: Used by Hermione in 1997 to copy Salazar Slytherin's locket in order to hide their tracks from Dolores Umbridge was also used on the locket when Sirius's brother Regulus Black stole the locket from Voldemort in the cave. Assumed that it was used on Gryffindor's sword by Snape.
Description: Causes the steps on a stairway to flatten and form a ramp, slide, or chute.
Seen/Mentioned: Used by Hermione to escape from pursuing Death Eaters in 1998. It is possible that the spell on the stairs to the girl's dormitories, which activates when boys try to climb the stairs, is the same .
Etymology: Possibly derived from the French verb glisser, meaning "to slide".
Description: Used to help someone grip something with more effectiveness. This charm is placed upon Quaffles to help Chasers carry the Quaffle whilst simultaneously holding their brooms.
Etymology: Harmonia Nectere Passus derives from the Latin word "harmonia", meaning "harmony", the Latin word "nectere" which means "to tie, bind", and the Latin term "passus" meaning "step, pace", which came from "pati" meaning "suffer, allow, undergo". Effectively, the entire phrase comes out to mean "Allow(ing) to bind the harmony." Basically, binding the rift between the sister Vanishing Cabinets.
Description: Reveals human presence in the vicinity of the caster.
Seen/Mentioned: Used multiple times by various people in 1997.
Etymology: Most likely from Latin homo, meaning human, and "reveal", though the classical Latin form would be hominem instead of homenum, which shows Portuguese influence ("man" is homem in Portuguese)—indeed, Rowling speaks the language.
Notes: It can be used non-verbally; Dumbledore does so to detect Harry underneath his Invisibility Cloak.[8]
Description: Causes an Animagus or transfigured object to assume its normal shape.
Seen/Mentioned: According to Lockhart, he used it to force the Wagga Wagga Werewolf to take its human form. It was, however, used by Lupin and Sirius on the rat named Scabbers to reveal that he was Peter Pettigrew in Prisoner of Azkaban.
Suggested Etymology: Latin homo meaning "person" and Greek morphosis meaning "shaping"
Seen/Mentioned: It was briefly mentioned in question 7 of the W.O.M.B.A.T. test on what should receive the lightest punishment by the Wizengamot "horns created on a culprits mother by a broken wand."
Description: This spell allows a part of a wizard's soul to pass into an object, thereby making the object a Horcrux. One has to commit murder and take advantage of the soul's "splitting apart" by this supreme act of evil in order to be able to perform this spell, and it is probably very complex. In 1943, Horace Slughorn described the spell to a young Tom Riddle as encasing a portion of the torn soul and placing it within an object. The spell itself is described in detail in a banned book known as "Secret of the Darkest Art", which Hermione Granger summoned from Albus Dumbledore's office near the end of their sixth year. According to the text, use of this spell to separate the soul will make the remaining portion of the soul very fragile, and can only be reversed by "remorse" of the wrongs the creator had made; however, the pain caused by attempting to reverse the creation of a Horcrux can destroy the individual.
Seen/Mentioned: Used by Lord Voldemort while creating his Horcruxes.
Notes: When J.K.Rowling was asked about what the steps are to create a Horcrux Rowling declined to answer, saying that "some things are better left unsaid". However, in the Harry Potter Encyclopedia, it is explained, and the editor is said to have felt like vomiting after reading it.
Seen/Mentioned: Used by Hermione Granger in 1995 to dry off her robes. Also used shortly after to melt snow. Also was used by Albus Dumbledore in 1997 to dry Harry's and his own robes. Quite possibly a form ofVentus.
Description: Causes brooms to vibrate violently in the air and try to buck their rider off.
Seen/Mentioned: In 1991, Professor Quirrell may have been casting a wordless and wandless version of this spell on Harry's broom during his Quidditch match. Professor Flitwick suggested that Harry's confiscatedFirebolt may be jinxed with this spell.
Description: This jinx 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 unclear.
Seen/Mentioned: Used in 1995 when Harry was practising for the Third Task of the Triwizard Tournament. In 1996, Harry saw in a memory that James Potter used it on Severus Snape. Also used in1997 by Harry against the Inferi and Snape. Stronger uses of this spell seem capable of blowing targets away.
Etymology: Latin impedimentum (plural impedimenta), "a hindrance" or "an impediment".
Description: One of the three "Unforgivable Curses". Places the subject in a dream-like state, in which he or she is utterly subject to the will of the caster. However, those who are strong willed may learn to resist it. The use of this curse on another human results in capital punishment or life sentence in Azkaban
Seen/Mentioned: Used on many occasions. First seen in 1994 whenBarty Crouch Jr, impersonating ex-AurorAlastor Moody, used it on a spider and later on students during a "class demonstration" in a Defence Against the Dark Arts class. While breaking into Gringotts in 1998, Harry used it on a goblin and a Death Eater when they became suspicious.
Etymology: Latin impero, I command, and English "imperious".
Description: Makes objects such as doors impenetrable (by everything, including sounds and objects).
Seen/Mentioned: The spell was used in 1995 by Hermione to trap Rita Skeeter within a bottle while she was in beetle form. It was also used by Molly Weasley in the same year on the door of the room in which an Order of the Phoenix meeting was being held, in order to prevent her sons, Fred and George, from eavesdropping.
Description: This spell makes something repel (literally, become impervious to) substances and outside forces including water.
Seen/Mentioned: Used by Hermione Granger in 1993 on Harry's glasses while in a Quidditch match and also by the Gryffindor Quidditch team. Also used in 1997, first by Ron to protect objects in Yaxley's office from rain, and then by Hermione to protect Harry, Ron and Griphook from the burning treasure in the Lestranges' vault.
Etymology: It is said that the Latin impervius means (and is the source of) "impervious"; although it is the source of the word, it is better translated as impassable, as in a mountain peak.
Etymology: Probably English incarcerate, "to imprison". Possibly linked to the Latin in carcerem, "in(to) prison".
Notes: A non-verbal version of this spell may have been used to tie upRemus Lupin by Severus Snape during the encounter in the Shrieking Shack, and then later Peter Pettigrew in 1994. It may also have been used by Quirrell in 1992, although he is said to have merely "snapped his fingers". Also, it may have been the spell Antonin Dolohov used non-verbally to bind Ron Weasley with "shinning black ropes" in a skirmish on Tottenham Court Road.
Seen/Mentioned: It was first seen in 1994 by Arthur Weasley to create a fire in the Dursleys' hearth so that he could use Floo powder there. In1997, this spell was used several times in battle, most noticeably when Hagrid's hut was set ablaze. It was also possibly used by Hagrid in 1991 to create a fire in the hearth before bringing Harry to London.
Etymology: Latin incendere, "to set fire (to)". Note that the first principal part of this verb (meaning "I set fire") is incendo, not incendio; Rowling's incantation does not match exactly any correct conjugation of the verb.Incêndio, in Portuguese (same pronunciation as in English) means 'huge fire'. "Encender" in Spanish means "to ignite" and "Incendie" in French means flame.
Notes: Probably the charm used frequently by Hermione, as it is noted that creating small portable fires is a speciality of hers. Although this fire is said to be portable and blue, which may be a different enchanted fire, possibly the bluebells flames incantation
Description: Informous is a spell that is used to complete one's Folio Bruti. A page with a brief description (including weaknesses and strengths) of the charmed creature is added to the caster's Folio Bruti.
