Engorgio (Engorgement Charm)-
Pronunciation: en-GOR-jee-oh
Description: Causes the target to swell in physical size.
Seen/Mentioned: Rubeus Hagrid used this spell on his pumpkins in 1992; two years later, Barty Crouch Jr. cast this spell on a spider to make it easier for students to see when he cast a curse on it. Used on another spider three years later to test a new wand.
Etymology: The English word engorge means "swell".
Notes: There is much speculation that this spell is the same as the Growth Charm, though this cannot be proven. Note that there is a difference between enlarging and engorging something, similar though they may seem.

Pronunciation: in-GORE-jee-oh SKUH-las
Description: This hex causes the victim's skull to swell disproportionately; this spell may be a variation of the Engorgement Charm, as they share the first word of the incantation. Its countercurse is Redactum Skullus.
Seen/Mentioned: This spell can be bought at Wiseacre's Wizarding Equipment in Diagon Alley.
Etymology: See etymology for above entry; "skullus" is Latin for "skull".
Entomorphis-
Pronunciation: en-TOE-morph-is
Description: This hex is used to transform the target into an insectoid for a short time; it can be bought at Wiseacre's Wizarding Equipment in Diagon Alley.
Seen/Mentioned: Harry Potter contemplated using this hex against Dudley Dursley in 1995, though he decided against it; it was later seen in the LEGO world.
Entrail-Expelling Curse:
Description: Presumably causes the victim's insides to be ejected from the body, though due to the fact that a portrait of its inventor was hung in a hospital, it is possible this spell's effect is entirely different.
Seen/Mentioned: It was only ever seen once, and that was when Harry Potter visited a hospital in 1996, and he saw the inventor's portrait.

Pronunciation: ee-PISS-key
Description: Used to heal relatively minor injuries, such as broken bones and cartilage.
Seen/Mentioned: In 1996, Nymphadora Tonks used this spell to fix Harry's broken nose after Draco Malfoy broke it on the Hogwarts Express (Luna Lovegood did so in the film); Harry, in turn, used it to heal Demelza Robins' swollen lip after Ron punched her during Quidditch practice.
Etymology: The word comes from Greek "episkeui" ("επισκευή"), which means "repair".
Notes: This is part of a family of healing spells.
Epoximise-
Pronunciation: ee-POX-i-mise
Description: Adheres one object to another, similarly to if they had been glued together.
Seen/Mentioned: As shown in the card game, this spell is often used by students to adhere each other's belongings to their desks (or, unfortunately, their hands).

Everte Statum-
Pronunciation: ee-VER-tay STAH-tum
Description: Throws the victim backward, similarly to if they'd been thrown.
Seen/Mentioned:Draco Malfoy used this spell on Harry Potter in 1992.
Etymology: The Latin words everte, which means "to throw out" and statua, from the same language, meaning "image".
Expecto Patronum (Patronus Charm)-
Pronunciation: ecks-PECK-toh pah-TROH-numb
Description: This charm is a defensive spell which will conjure a spirit-like incarnation of their positive emotions to defend against dark creatures; it can also send messages to other witches or wizards. It seems one's Patronus will take the form of something important to the caster, and can change when one has undergone a period of heightened emotion.
Seen/Mentioned: Taught to Harry by Professor Lupin; Harry later taught Dumbledore's Army this charm. This is the only spell effective against Lethifolds.
Etymology: Patronus means "protector" in Latin; in archaic Latin, it means "father"; considering the form Harry's takes, this is interesting. The Latin word expecto means "I await"

Pronunciation: ex-PELL-ee-ARE-muss
Description: Causes whatever the victim is holding to fly away, knocks out an opponent if used too forcefully. Harry Potter's special spell.
Seen/Mentioned: Used multiple times from the second book onwards.

Notes: Mentioned in Doctor Who starring David Tennant and Freema Agyeman, second episode of third series.

Extinguishing spell-
Description: Puts out fires.
Seen/Mentioned: Charlie Weasley and his friends would use this spell should something go wrong in the tournament.

Description: Makes something lightweight.
Seen/Mentioned: Harry Potter contemplated using this in 1993 to lighten his trunk so that he could carry it by broom to Gringotts, though he decided against it.
Notes: This charm may have been cast by Hermione Granger on her beaded bag to make it easier to carry, considering the heavy objects within.
Ferula-
Pronunciation: feh-ROO-lah
Description: Creates a bandage and a splint.
Seen/Mentioned: Used by Remus Lupin in 1994 to bind Ronald Weasley's broken leg.
Etymology: Latin ferula means "walking-stick" or "splint".
Fianto Duri-
Pronunciation: fee-AN-toh DOO-ree
Description: A defensive charm which, based on the etymology, strengthens shield spells, and perhaps objects in general, in a similar way to Duro.
Seen/Mentioned: Used to protect a school in 1998.
Etymology: Latin fiant means "become" and duri means "hard".

Description: A complex charm used to hide secret information within the soul of the charm's recipient, who is called a Secret-Keeper. The information is irretrievable unless the Secret-Keeper chooses to reveal it, and only the aforementioned person can do so.
Seen/Mentioned: In 1993, it was explained that when Harry was merely an infant, he and his parents were hidden from Voldemort with this charm; from 1995 onward it was used to protect Grimmauld Place, and in 1998 it was used to protect Shell Cottage.
Etymology: Latin fidelis, which means "faithful".
Notes: Although the author had previously explained that when a Secret-Keeper dies the secret they held can never be revealed to anyone else[6], in 1997 it is clearly explained that upon the Keeper's death all those who had been told the secret become keepers in turn.
Notes (2): This charm seems to have no effect with regard to animals, as Hedwig found Ron and Hermione in a location that was protected by this charm; however, it is possible that Dumbledore somehow told her, ludicrous though such may seem.
Notes (3): In 1981, Hagrid managed to get to Harry before all the Muggles could look at it; this makes it appear as though the Killing Curse will negate the effect of the Fidelius Charm.
Notes (4): Those who have been told of the secret by secret-keepers still cannot pass the secret on, as proven by Severus Snape and Bellatrix Lestrange.
Fiendfyre-
Description: Creates great spirits of fire which burn anything in its path, including nearly indistructable substances such as horcruxes. This fire is nearly impossible to control.
Seen/Mentioned: Though there are numerous instances when it may have been used, it was only proven to have been used in 1998 by Vincent Crabbe, who was killed by it.

Etymology: From the Latin flagrate, meaning "a burn".

Description: Causes fire to tickle those caught in it instead of burning them.
Seen/Mentioned: Third year students wrote an essay on the use of this charm in medieval witch-burnings; Wendelin the Weird was burned forty-seven times.

Seen/Mentioned: Hermione Granger designed and placed this jinx on the parchment signed by all members of Dumbledore's Army. When Marietta Edgecombe betrayed the D.A. to Dolores Umbridge, the jinx was triggered.
Notes: This jinx was invented by Hermione, and may have been inspired by Furnunculus.

Pronunciation: HOM-eh-num reh-VEH-lee-oh
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.

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.

(Horton-Keitch Braking Charm)-
Description: This spell was first used on the Comet 140 to prevent players from overshooting the goal posts and from flying off-sides.
Seen/Mentioned: Mentioned in Quidditch Through the Ages as the charm that gave the Comet 140 an advantage over the Cleansweep.
(Horcrux Curse)-
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.

Description: Causes wand to emit hot air.
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 of Ventus.

Description: Causes the target to float in mid-air for a brief period of time.
Seen/Mentioned: Used by Dobby to levitate a cake.

Pronunciation: i-lej-i-bill-us
Description: Illegibilus is a spell that is used to render a text illegible.


Pronunciation: eem-o-bue-les
Description: Renders living targets immobile.
Seen/Mentioned: Hermione used it 1992 to freeze 2 Cornish Pixies. According to Horace Slughorn, a Freezing Charm will disable a Muggle Burglar Alarm. It strikes resemblances to the Flame-Freezing Charm, which negates the effects of fire.
Etymology: From the Latin “immobilis”, meaning immovable.
Notes: The Incantation was mentioned in the film adaptations of Chamber of Secrets.
Remus Lupin also used it on the womping willow in the third movie when they use the time turner.

Pronunciation: im-ped-ih-MEN-tah

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 in 1997 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".

Pronunciation: im-PEER-ee-oh
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 when Barty Crouch Jr, impersonating ex-Auror Alastor 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.
Impervius (Impervius Charm)-
Pronunciation: im-PUR-vee-us
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.
Inanimatus Conjurus (Inanimatus Conjurus Spell)-
Pronunciation: in-an-ih-MAH-tus CON-jur-us
Description: It is a spell of unknown effect, most likely used to conjure an inanimate object.
Seen/Mentioned: Mentioned briefly in 1995.

Pronunciation: in-CAR-ser-us
Description: Ties someone or something up with ropes.
Seen/Mentioned: First heard in 1996, when Dolores Umbridge tries to hold off Centaurs. Also used by Harry on the Inferi in Voldemort's Horcrux cave in 1997.
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 up Remus 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 "shining black ropes" in a skirmish on Tottenham Court Road.
Notes (2): It can be bought at Wiseacre's Wizarding Equipment in Diagon Alley in LEGO Harry Potter: Years 1-4.

Pronunciation: in-SEN-dee-oh
Description: Produces fire.
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. In 1997, 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. (A plausible but less likely source might be that it is a back-formation from the English word "incendiary," i.e., "causing fire.")
Notes: Probably the charm used frequently by Hermione, as it is noted that creating small portable fires is a speciality of hers. This fire is said to be portable and blue, which may be a different enchanted fire, possibly the bluebells flames incantation.
Incendio Duo-
Pronunciation: in-SEN-dee-oh DOO-oh
Description: A stronger version of Incendio.
Seen/Mentioned: It was in Harry Potter and the Chamber of Secrets (GBC)

Pronunciation: in-FLAY-tus
Description: Inflates objects (living or dead).
Seen/Mentioned: One of the secondary spells in Harry Potter and the Goblet of Fire (video game) or possibly in "Harry Potter and the Prisoner of Azkaban (film).
Etymology: The prefix 'Inflate' derives from the English verb "to expand with oxygen".
Informous (Informous Spell)-
Pronunciation: in-FOR-m-es
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.
Seen/Mentioned: This was seen in the video game version of Harry Potter and the Chamber of Secrets (GBC version)
Etymology: The prefix Info derives from the English verb "to inform".
(Intruder Charm)-
Description: Detects intruders and sounds an alarm.
Seen/Mentioned: Horace Slughorn used it on a Muggle-owned house he stayed in temporarily in 1996, but did not hear it go off when Albus Dumbledore and Harry Potter arrived, as he was in the bath.

Description: Causes the victim's legs to collapse.
Seen/Mentioned: One of the spells mentioned in Curses and Counter-Curses by Vindictus Viridian, used on Harry, practising for the Third Task of the Triwizard Tournament, by Hermione. Also, Draco Malfoy was hit with this jinx (along with another one) at the end of the term.
(Jelly-Brain Jinx):
Description: Presumably affects the target's mental processes.
Seen/Mentioned: During the September 1999 riot that took place during the Puddlemere United/Holyhead Harpies Quidditch game, a lot of Harpy supporters were using this jinx.
Notes: This spell may have been the spell that the Death Eaters hit Ron with in Harry Potter and the Order of the Phoenix in the Battle of the Department of Mysteries.
(Jelly-Fingers Curse):
Description: Causes the target's fingers to become almost jelly-like to make it uneasy for the victim to grasp objects.

Description: It sends a ball of fire from the wand
Seen/Mentioned: Used by Hermione in 1991 to stop Snape from cursing Harry. The incantation is only used in the film adaptation of Harry Potter and the Philosopher's Stone.

Langlock-
Pronunciation: LANG-lock
Description: Glues the subject's tongue to the roof of their mouth. Created by Severus Snape.
Seen/Mentioned: Used by Harry on Peeves and twice on Argus Filch, to general applause.

Etymology: Latin legere ("to read") and mens ("mind").


Pronunciation: lev-ee-COR-pus
Description: The victim is dangled upside-down by their ankles, sometimes accompanied by a flash of light (this may be a variant of the spell).
Seen/Mentioned: Apparently invented by the Half-Blood Prince; it is a non-verbal-only spell (although it is whispered by Hermione in 1997). Harry Potter learnt it by reading the notes written by the Half-Blood Prince. He used it on Ron. The previous year, Harry had seen (through the Pensieve used by Severus Snape) his father, James Potter, use the spell against Professor Snape. In the Order of the Phoenix film, Luna Lovegood somehow uses this against a Death Eater, although she speaks it, and the spell's name is unknown to any students until Half-Blood Prince.
Etymology: Latin levare, "raise" and corpus, "body".
Liberacorpus-
Pronunciation: LIB-er-ah-cor-pus
Description: Counteracts Levicorpus.
Seen/Mentioned: Harry used the spell in 1996 to counteract Levicorpus he had inadvertently cast on Ron.
Etymology: Latin liberare, "to free", and corpus, "body".
Notes: It is not clear why Levicorpus has a specific counter-spell, and is not neutralized by simply using Finite Incantatem, although this could be due to the fact that Snape invented the spell and therefore made it irreversible except by its specific counter-curse.

Pronunciation: LOH-koh-moh-tor
Description: The spell is always used with the name of a target, at which the wand is pointed (e.g. "Locomotor Trunk!"). The spell causes the named object to rise in the air and move around at the will of the caster.
Seen/Mentioned: Used by Nymphadora Tonks in Harry Potter to move Harry's trunk from his room. Filius Flitwick similarly used it to move Sybill Trelawney's trunk after Dolores Umbridge sacked her. Parvati Patil and Lavender Brown used this spell to race their pencil cases around the edges of the table. A variation seen in 1998 is Piertotum Locomotor, which caused the statues of Hogwarts to be animated.
Etymology: Latin locus (place) and moto, "set in motion" (passive motor), or English locomotion.

Pronunciation: LOH-koh-moh-tor MOR-tis
Description: Locks the legs together, preventing the victim from moving the legs in any fashion.
Seen/Mentioned: Used by Draco Malfoy on Neville Longbottom in 1991. Used by Harry Potter on Draco Malfoy, who deflected it, in 1996. One of the spells on Pottermore.
Etymology: English locomotion, "movement" + Latin mortis, "of death".
Notes: It is unclear whether or how this spell is related to the Locomotor spell. It could, however, be that the curse "locks" any part of the body in accordance to where it is pointed, or moves the body into a position of the caster's choosing whilst placing them into an immobile state. It is possible that Draco had pointed his wand at Neville and the curse "locked" his legs together.
Notes (2): It can be bought at Wiseacre's Wizarding Equipment in Diagon Alley in LEGO Harry Potter: Years 1-4.
Lumos (Wand-Lighting Charm)-
Pronunciation: LOO-mos
Description: Creates a narrow beam of light that shines from the wand's tip, like a torch.
Seen/Mentioned: Constantly throughout the series. A stronger version of this spell, Lumos Maxima is performed by Harry Potter at the Dursleys' house in the film adaptation of Harry Potter and the Prisoner of Azkaban, and by both Harry and Dumbledore in the Horcrux cave in the film adaptation of Harry Potter and the Half-Blood Prince. Used in Pottermore.
Etymology: Latin lumen, "light".
Notes: opposite incantation, Nox, puts the light out.
Lumos Duo-
Pronunciation: LOO-mos DOO-oh
Description: Creates an intense beam of light that projects from the wand's tip and can lock-on to various targets, turn hinkypunks solid and cause ghouls to retreat.
Seen/Mentioned: Learned and used by Ron in the video game adaptation of Harry Potter and the Prisoner of Azkaban.
Etymology: Lumos plus Latin duo, "two".
Lumos Maxima-
Pronunciation: LOO-mos Ma-cks-ima
Description: Shoots a ball of light at the place pointed, if the Wand is swung.
Seen/Mentioned: First practiced by Harry in the home of the Dursleys, then used by Dumbledore to light up the cave of the Horcrux.
Etymology: Lumos + maxima, Latin "greatest."
Lumos Solem-
Pronunciation: LOO-mos SO-lem
Description: Creates a powerful ray of light as bright as the sun.
Seen/Mentioned: Used by Hermione to free Ron from the Devil's Snare. The incantation was only used in the film adaptation of Harry Potter and the Philosopher's Stone.
Etymology: Derived from two words; the Latin lumen, meaning "light", and the Latin word for "sun", which in its accusative case is "solem".
Notes: It is possible that the quality of the light is on the warmer solar end of the spectrum; Considering the known uses that the spell has been put to, it isn't that much of a stretch to presume that the spell is used to conjure Sunlight.
Magicus Extremos-
Description: Throw Spell with more Power.
Seen/Mentioned: Harry Potter and the Goblet of Fire (video game)
Melofors (Melofors Jinx)-
Description: Encases the target's head in a pumpkin.

Meteolojinx Recanto-
Pronunciation: mee-tee-OH-loh-jinks reh-CAN-toh.
Description: Presumably causes weather effects caused by jinxes to cease.
Seen/Mentioned: Suggested in 1997 by Arthur Weasley to Ron (disguised as Reginald Cattermole by use of Polyjuice Potion) as the best way to clear up the rain jinx on a Ministry office. Also used by Bartemius Crouch Jr. (Disguised as Alastor Moody) In 1994 to cease the weather effect of the Great Hall's Ceiling insisting it is broken as he told Dumbledore to "Fix his ceiling".
Etymology: Meteorology, the study of weather, the word jinx and recant, "to withdraw or retract". Interestingly in modern English recant means to say that you no longer hold a belief.
Mimblewimble (Tongue-Tying Curse)-
Pronunciation: MIM-bull-WIM-bull
Description: A curse which prevents certain information from being revealed by the individual upon whom the spell is placed. The curse manifests itself by causing the tongue to temporarily curl backwards upon itself.

Mobiliarbus-
Pronunciation: MO-bil-ee-AR-bus
Description: Levitates and moves an object.
Seen/Mentioned: In 1993, Hermione Granger used the spell to move a Christmas Tree in The Three Broomsticks beside her table to hide Harry Potter, who was in Hogsmeade illegally.
Etymology: Latin mobilis, "movable" or "flexible", and arbor (alternatively arbos), "tree".
Notes: It is possible that Mobilicorpus and Mobiliarbus are variations of the same basic spell, since they share the "Mobili-" stem.
Mobilicorpus-
Pronunciation: MO-bil-ee-COR-pus
Description: Levitates and moves bodies.
Seen/Mentioned: Sirius Black used it on Severus Snape in 1994. It was probably used on Peter Pettigrew by Lord Voldemort in the graveyard to make him come forward.
Etymology: Latin mobilis, "movable", and corpus, "body".
Notes: It is possible that Mobiliarbus and Mobilicorpus are variations of the same basic spell, since they share the "Mobili-" stem.
Molly Weasley's Curse-
Pronunciation: Unknown
Description: Like the Avada Kedavra curse, it kills (or freezes) the victim. It turns the body grey/blue (or paler) while it turns to stone and then another twin jinx can blast the body into pieces.
Seen/Mentioned: Molly Weasley used the curse after Bellatrix Lestrange attacked Ginny Weasley. Only used in the film version.
Notes: This may be Duro or a Freezing Charm, although the latter is shown to be blue in 1992.
Morsmordre (Dark Mark)-
Pronunciation: morz-MOR-duh, morz-MOHR-dah, morz-MOR-drah
Description: Conjures the Dark Mark.
Seen/Mentioned: Used by Barty Crouch Jr in 1994. Also seen in 1997 over the castle to lure Albus Dumbledore to his death. It was apparently invented by Lord Voldemort.
Etymology: Latin mors, "death", and mordere, meaning "to bite" (or its French derivative mordre); this would appear to be associated with the name of Lord Voldemort's followers, the Death Eaters. The English murder might also contribute.
Notes: A possible translation might be "take a bite out of death", a fitting phrase for Death Eaters.
Muffliato (Muffliato)-
Pronunciation: muf-lee-AH-to
Description: This spell fills peoples' ears with an unidentifiable buzzing to keep them from hearing nearby conversations.
Seen/Mentioned: It was used in 1996 by Harry Potter and Ron Weasley on various teachers and people such as Madam Pomfrey. It was created by Severus Snape. As pointed out by Hermione, it is probably not Ministry of Magic approved. It was also used in 1997 by Hermione Granger in protection of the camp-site where Harry and she stayed in hiding.
Etymology: English muffle, "to quiet", with a pseudo-Latin or pseudo-Italian ending.
Multicorfors-
Pronunciation: mull-tee-COR-fors
Description: Multicorfors is a charm used to change the colour of one's clothing.
Seen/Mentioned: It can be bought at Wiseacre's Wizarding Equipment in Diagon Alley in LEGO Harry Potter: Years 1-4. It may also be the same charm as when Harry accidentally changed the colour of his eyebrow, before he asked Luna to Slughorn's Christmas party. (Unlikely, as that was performed as a Transfiguration exercise, which is rather unrelated to Charms.) Could have possibly been used when Harry accidentally changed the colour of his teachers hair, in his Primary School.
Nox (Wand-Extinguishing Charm)-
Pronunciation: Nocks
Description: Turns off the light produced by Lumos.
Seen/Mentioned: In 1994, Harry Potter and Hermione Granger used this spell to turn off their wand-lights in the Shrieking Shack. Used in 1998 when Harry was in the passage beneath the Whomping Willow which leads to the Shrieking Shack. Lumos's power can be arranged so that a powerful wizard can make the charm illuminate intensely or to the wizards liking by loudness of incantation. For example "LUMOS!!!" would be powerful and "lumos" would be weaker. Also used by Harry Potter in 1998 to turn off the light so he could hide the Marauder's Map from Severus Snape.
Etymology: Latin nox, meaning "night".
Oculus Reparo-
Description: Mends eyeglasses.
Seen/Mentioned: Used by Hermione in 1991 and 1992 to fix Harry's glasses.
Notes: This spell is a variation of Reparo.
(Obliteration Charm)-
Description: Removes footprints.
Seen/Mentioned: Used by Hermione in 1995 to remove the footprints that she, Harry, and Ron left in the snow while walking to Hagrid's hut. Also used in 1997 by Hermione to remove the footprints she and Harry left behind them in the snow as they journeyed through Godric's Hollow.
Notes: The above instance in book five only reveals that the Obliteration Charm can remove footprints. There is no explanation as to what effect it can have on other things. It could possibly destroy things, according to its name.
Obliviate (Memory Charm)-
Pronunciation: oh-BLI-vee-ate
Description: Used to hide a memory of a particular event.
Seen/Mentioned: First seen in 1993 when used by Gilderoy Lockhart on Harry and Ron; the spell backfired due to a faulty wand, costing Lockhart most of his own memory. Also, Hermione Granger used this spell to wipe her parents memories in 1997. Again, it was used in 1997 when Hermione Granger used the spell on 2 Death Eaters who had followed Harry, Ron, and Hermione after their escape from Bill Weasley's and Fleur Delacour's wedding.
Etymology: Latin oblivisci, "forget". The spell is most often used against Muggles who have seen something of the Wizarding world.
Notes: Memory Charms are confirmed on J.K. Rowling's website to have been developed by a witch named Mnemone Radford, who became the Ministry's first Obliviator. The Ministry of Magic employees assigned to modifying the memories of Muggles are called Obliviators. The charm can be broken by powerful magic, or extreme duress, as Lord Voldemort was able to torture Bertha Jorkins into remembering details that Barty Crouch Sr had forced her to forget using the charm. In this case, it was also shown that if the charm is too powerful, it can cause the target to develop a bad memory. This spell differs from the False Memory Charm.
Obscuro-
Pronunciation: ob-SK(Y)OOR-oh
Description: Causes a blindfold to appear over the victim's eyes, obstructing their view of their surroundings.
Seen/Mentioned: Used by Hermione Granger in 1997 to obstruct the portrait of Phineas Nigellus's view of their location.

Etymology: English word obscure, meaning "unclear" or "unnoticeable".
Oppugno (Oppugno Jinx)-
Pronunciation: oh-PUG-noh
Description: Apparently causes animals or beings of lesser intelligence to attack.

Etymology: Latin oppugno, "

Pronunciation: OR-biss

Seen/Mentioned: Used multiple times in 1993.
Etymology: Orbis is Latin for 'circle', which reflects the spell's physical appearence.
Orchideous-
Pronunciation: or-KID-ee-us
Description: Makes a bouquet of flowers appear out of the caster's wand.
Seen/Mentioned: Used in 1994 by Mr. Ollivander to test Fleur Delacour's wand. Probably used non-verbally by Tom Riddle to present flowers to Mrs. Smith.
Etymology: English orchid and Latin suffix -eous, "of or bearing (the root word)".
Notes: A variation of this spell may have been used when Hermione Granger conjured a Christmas wreath to place on James and Lily Potter's graves in 1997.

Pronunciation: pak
Description: Packs a trunk, or perhaps any luggage.
Seen/Mentioned: Used in Harry Potter and the Prisoner of Azkaban by Remus Lupin in his office, and in Harry Potter and the Order of the Phoenix by Nymphadora Tonks, once verbally and again non-verbally.
(Patented Daydream Charm)-
Pronunciation: Unknown
Description: Gives the spell caster a highly-realistic 30-minute daydream. Side effects include mild drooling and a vacant expression.
Seen/Mentioned: These were invented by Fred and George Weasley and sold in 1996 at their joke shop, presumably in the form of some kind of physical object, similar to Skiving Snackboxes.

Pronunciation: par-tís temp-oar-us
Description: Creates a temporary gap through protective magical barriers.
Seen/Mentioned: Used by Albus Dumbledore in the Horcrux cave in the film version of Harry Potter and the Half-Blood Prince. He uses it so that he and Harry can pass through the ring of fire used to ward off the Inferi.
Etymology: Partis is a plural form of the French verb partir, which means "to separate," "to go away," "to leave," or "to depart." Temporis is Latin for "time."
Periculum-
Pronunciation: pur-ick-you-lum
Description: Creates red sparks/flares to shoot from the users wand
Seen/Mentioned: Used during the third task of the Tri-wizard Tournament by Harry. Also believed to have been used in Pottermore, but is called the "Red Sparks Spell".
Etymology: Periculum is Latin for "danger".

Pronunciation: PES-key PIX-ee PES-ter NO-mee
Description: The one time it was used, it had absolutely no effect.
Seen/Mentioned: Used by Lockhart to attempt to remove Cornish Pixies.
Suggested Etymology: English pesky meaning "annoying", English pixie meaning "a supernatural being", English pester meaning "to annoy", English no for negative and English me for the first person pronoun.
Notes: It is not known if the spell works or not. It also suspiciously sounds like "Pesky pixie pester no me."
Petrificus Totalus (Full Body-Bind Curse)-
Pronunciation: pe-TRI-fi-cus to-TAH-lus
Description: Used to temporarily bind the victim's body in a position much like that of a soldier at attention; the victim will usually fall to the ground.
Seen/Mentioned: First used in 1991 by Hermione, who was trying to prevent Neville from stopping her, Ron, and Harry from leaving the common room to hunt for the Philosopher's Stone. Also used in the Hall of Prophecy in the film adaptation of Harry Potter and the Order of the Phoenix to petrify one of the Death Eaters pursuing the group. Also used on Harry by Draco Malfoy in the train in Harry Potter and the Half-Blood Prince. Used also in Pottermore.
Etymology: Latin petra, meaning "stone", and fieri (past participle factus), meaning "to become"; totalus comes from Latin "totus", meaning "complete".
Note: Albus Dumbledore used Petrificus Totalus on Harry during the first Battle of Hogwarts while Draco Malfoy disarmed him.

Description: A charm which temporarily places an object upon a desired target.
Seen/Mentioned: Mentioned in Fantastic Beasts and Where to Find Them.
Point Me (Four-Point Spell)-
Pronunciation: English phrase
Description: Causes the caster's wand to act as a compass, and point North.
Seen/Mentioned: Hermione Granger taught it to Harry Potter, who used it during the Triwizard Tournament, particularly to navigate the hedge maze during the Third Task.
Note: This spell may be an invention of Hermione Granger; it is unclear in the Goblet of Fire text whether she invented it herself or found it through research. Given that the incantation is English (whereas almost all other mentioned spells have incantations based on Latin or other old languages) and that none of the other champions of the Tournament seem to use the spell, it seems likely that Hermione invented the spell.
Portus-
Pronunciation: POR-tus
Description: Turns an object into a port-key
Seen/Mentioned: Used by Albus Dumbledore in 1996.
Etymology: Latin porta, meaning "gate", or portare, meaning "to carry" (as in to carry the caster or target to another location). There is a Latin word portus, meaning "harbour", but it is inappropriate in this context.
Notes: Portkeys were first seen in 1994 as a means for Harry, Hermione, and the Weasleys to go to the Quidditch World Cup. However, the spell used in its creation was not seen until 1995.

Pronunciation: pri-OR in-can-TAH-toh
Description: Causes the echo (a shadow or image) of the last spell cast by a wand to emanate from it.
Seen/Mentioned: Used by Amos Diggory in 1994 to discover the last spell cast by Harry's wand after it was found in the hands of Winky, a house-elf.
Etymology: Latin prior, "previous", and incantare, "to speak a spell" (past participle incantatum).
Notes: The nature of the "echo" depends on the original spell. The echo of a conjuring spell, for example, is the object conjured; the echo of the Cruciatus Curse is the screaming of the victim; the echo of an Avada Kedavra curse is the image of its victim.
Notes(2): Amos Diggory used this spell to find out if Harry's wand (held by Winky, Bartemius Crouch's house elf) cast the Dark Mark.
Notes(3): Apparently the spell is cumulative, with the user able to go further back and see spells that the wand performed after the latest spell. Harry suggests this in 1997. Hermione does not contradict his claim, suggesting this is true.
(Protean Charm)-
Description: Causes copies of an object to be remotely affected by changes made to the original.
Seen/Mentioned: First used in 1995. Hermione Granger put the charm on a number of fake Galleons. Instead of the serial number around the edge of the coin, the time and date of the next meeting of Dumbledore's Army appeared. It is possible that this charm is used on the Death Eaters' Dark Marks.
Etymology: The English word Protean derives from Proteus, a god in Greek Mythology. Proteus was a shape-shifter, able to take many forms. As a result, the word Protean has come to refer to versatility, flexibility, or an ability to assume many forms. "Protean" is also similar to "protein", derived from the same root, meaning a variable, flexible substance which forms strong bonds between its constituent parts.
Notes: On Hermione's fake galleons, when the date changes, the coin becomes hot, alerting the owner to look at the coin. This may not be a feature of the original charm. It may be a Flagrante Curse, when the Protean Charm changes the coin the curse may activate. It would seem from this that you can decide what the effects on the charmed objects are. Possibly by saying something along the lines of "Protean flagrante." although this is just speculation
Notes (2): The Protean Charm is a N.E.W.T. standard charm, according to Terry Boot, who is incredulous that Hermione can perform the spell even though she is only in her fifth year (N.E.W.T.s are taken in the seventh year at Hogwarts).

Pronunciation: pro-TAY-goh
pro-te-goh
Description: The Shield Charm causes minor to moderate jinxes, curses, and hexes to rebound upon the attacker.
Seen/Mentioned: First seen in 1995, in which Harry is taught this spell by Hermione in preparation for the third task in the Triwizard Tournament. Albus Dumbledore uses a similar spell which reverses the construction of glass back into sand when Voldemort sent shards of glass to try to stab Dumbledore. Fred and George Weasley enchanted hats they dubbed "shield hats" with this spell in 1997.
Etymology: Latin protego, "I cover" or "I protect".
Notes: The original description of this spell states that it rebounds minor jinxes to the caster. However, it is shown in the books that it can also be used to reflect or lessen the effects of more powerful spells, depending on the skill of the caster. In 1998, it is also shown to be able to create a sort of force-field across an area, and is used frequently to prevent two participants in an argument from reaching each other.
Protego Horribilis-
Pronunciation: pro-TAY-goh horr-uh-BIHL-ihs
Description: A powerful shield charm against dark magic.
Seen/Mentioned: Cast by Professor Flitwick in an attempt to strengthen the castle's defences in the Battle of Hogwarts.
Etymology: Latin Protego, "I protect", and Horribilis, "horrible , frightful,

Pronunciation: pro-TAY-goh MAX-ee-Ma
Description: A powerful shield charm against dark magic. Was so powerful that it could also disintegrate people that came too close.
Seen/Mentioned: Cast by Professor Flitwick, Professor McGonagall, Professor Slughorn and Mrs. Weasley in an attempt to strengthen the castle's defences in the Battle of Hogwarts.
Etymology: Latin Protego, "I protect"
Protego Totalum-
Pronunciation: pro-TAY-goh prah-TEH-go toh-TAH-lum
Description: Casts a shield charm over a small area that will not let anything pass through. Except for the Unforgivable Curses: Avada Kedavra, Imperio and Crucio .
Seen/Mentioned: In 1997, this was one of the spells used by Hermione Granger and Harry Potter to protect their camp site from unwanted visitors.
Etymology: Latin protego meaning "to protect" and Latin totus meaning "as a whole".

Description: Causes purple firecrackers to shoot out from the tip of one's wand.
Seen/Mentioned: On 31 October 1991, Albus Dumbledore used this spell to get the attention of panicking diners in the Great Hall when a troll was loose in the castle.
(Pus-squirting hex):
Description: Causes yellowish goo to squirt from one's nose.
Seen/Mentioned: Morfin Gaunt used this hex on Bob Ogden.

Pronunciation: KWIY-uh-tus
Description: Makes a magically magnified voice return to normal. A counter to Sonorus.
Seen/Mentioned: Used in 1994 by Ludo Bagman.
Etymology: Latin quietus, "calm" or "quiet".
Notes: It is conjectural whether Quietus could be used alone to magically quiet a person's voice, or only counteracts Sonorus.

Pronunciation: red-AK-tum SKULL-us
Description: Redactum Skullus is a hex that shrinks the target's head. It is the counter-spell to Engorgio Skullus.

Reducio (Shrinking Charm):
Pronunciation: re-DOO-see-oh
Description: Makes an enlarged object smaller. Counter-charm to Engorgio.
Seen/Mentioned: In Harry Potter and the Deathly Hallows: Part 1, Harry Potter, after checking his Blackthorn wand on the Bluebell flames with Engorgio, casts this spell to shorten the formerly enlarged flames.
Etymology: English reduce, "to shrink". (Latin has a verb reducere, present tense reduco. This is the source of the English "reduce", but has a different meaning.) Also in Italian Riduco first person present tense of Ridurre, same root of Latin Reducere.
Notes: Whether Reducio could also be used by itself rather than countering Engorgio is unknown. If it could, it would shrink normal sized items into miniature versions of themselves. References in 1992 by Arthur Weasley to "shrinking door keys" make this seem likely.

Pronunciation: re-DUK-toh
Description: Breaks objects. In stronger usages, disintegrates them.
Seen/Mentioned: In 1995, Harry used it on one of the hedges of the Triwizard maze and ends up burning a small hole in it; in 1995, Gryffindors in Harry Potter's year referenced Parvati Patil as being able to reduce a table full of Dark Detectors to ashes, and Harry and his friends later used the spell in the Department of Mysteries against the Death Eaters, shattering many Prophecy Orbs in the process; in 1997, a member of the Order of the Phoenix attempted to use this spell to break down a door which Death Eaters had blocked when the Death Eaters had cornered Dumbledore in the Lightning Struck Tower.
Etymology: English reduce, "to bring down;destroy".
Notes: Reparo makes a good counter-curse.
(Refilling Charm):
Description: Refills whatever the caster points at with the drink originally in the container.
Seen/Mentioned: Used in Harry Potter and the Half-Blood Prince, when Harry notices that Hagrid and Slughorn are running out of wine. This may have also been in the Harry Potter and the Deathly Hallows: Part 1 film as the water in the cups are shown refilling themselves.
(Reparifors):
Description: Reverts minor magically-induced ailments, such as paralysis and poisoning.
Seen/Mentioned: Harry Potter and the Prisoner of Azkaban (video game)

Pronunciation: Re-LASH-ee-oh
Description: A spell used to make the subject release what ever it is holding or binding.
Seen/Mentioned: Used by Harry Potter against Grindylows in the second task of the Triwizard Tournament. Also used in 1997 and 1998, when Hermione used this spell to free Mrs. Cattermole from the chained chair and to free the Ukrainian Ironbelly on which they were to get out from Gringotts.]]
Etymology: Probably from the French verb relâcher ="to release, to set free", or Italian rilascio (pronounced the same way as the spell)= "I release".
Rennervate:
Pronunciation: ree-nur-VAH-tay, REN-ur-vayt
Description: revives a stunned person.
Seen/Mentioned: In 1994, Amos Diggory used it to wake up Winky and Albus Dumbledore used it to wake up Viktor Krum. Harry Potter later used it to try and reawaken a cursed Dumbledore in the seaside cave.
Etymology: Officially renamed from Ennervate by J.K. Rowling.Rennervate means "to energize", whilst the former Ennervate, meant "to weaken,".

Pronunciation: This information is currently unknown.
Description: Used to reverse unsuccessful transformations.
Seen/Mentioned: Seen only thus far in A Beginner's Guide to Transfiguration on Pottermore.
Etymology: This information is currently unknown.
Reparo (Mending Charm)-
Pronunciation: reh-PAH-roh
Description: Used to repair objects.
Seen/Mentioned: Countless times throughout the books. Shattered objects are often described as having "flown" back together. However, substances contained in the broken objects don't get back inside. In 1995 Harry smashed a bowl of murtlap essence. He could repair the bowl but the murtlap essence remained splashed to the floor.
Etymology: Latin reparo meaning "to renew" or "repair".
Notes: This is the final spell used in the Harry Potter series. Reparo has been seen to repair non-magical items, however it seems to have an inability at repairing magical items or items that have magic placed upon them. An example is Harry's Nimbus 2000 shown in 1993 which he is told is irreparable after it is destroyed by the Whomping Willow. Wands are also irreparable, as shown in 1992 when Ron's wand snapped after he and Harry crashed onto the Hogwarts grounds. Despite his use of Spellotape, Ron's wand malfunctioned throughout the entire novel. Another example is in 1997 when Hermione tried to fix Harry's broken wand, which was snapped by her errant Blasting Curse. However, Harry repaired his wand with the Elder Wand. Since the Elder Wand is the most powerful wand in the universe, it makes sense that it would produce the most powerful Repairing Charm.

Pronunciation: reh-PELL-loh MUG-ul-tum, MUGG-gleh-tum, mugg-GLEE-tum
Description: Keeps Muggles away from wizarding places by causing them to remember important meetings they missed and to cause the Muggles in question to forget what they were doing.
Seen/Mentioned: Mentioned in Quidditch Through the Ages as being used to keep Muggles away from the Quidditch World Cup. Hogwarts was also said to be guarded by the Muggle-Repelling Charm. It was also used by Harry and Hermione on numerous occasions, among many other spells, to protect and hide their camp site in 1997.
Repello Inimicum-
Pronunciation: re-PEH-lloh ee-nee-MEE-cum
Description: Disintegrates the persons entering this charm.
Seen/Mentioned: This spell was used by professors Filius Flitwick and Horace Slughorn along with Order of the Phoenix member Molly Weasley to protect Hogwarts Castle in 1998.
Etymology: Latin "Repello", meaning "Push Back" and "inimicum", the accusative singular form of "inimīcus" meaning "foe" or "enemy".

Pronunciation: rih-dih-KYU-lus
Description: A spell used when fighting a Boggart, "Riddikulus" forces the Boggart to take the appearance of an object the caster is focusing on. Best results can be achieved if the caster is focusing on something humorous, with the desire that laughter will weaken the Boggart.
Seen/Mentioned: First seen in 1993, when taught by Remus Lupin.
Etymology: Latin word ridiculus, "laughable" (but perhaps "absurd" or "silly" in this context).
Notes: The effect of the spell seems to rely primarily on the state of mind of the caster. It doesn't actually change the shape of a boggart into something humorous, but rather whatever the caster is concentrating on at the moment of the casting, as when Neville was thinking of his grandmother's dress. Presumably, Mrs. Weasley couldn't take her mind off of her fears for her family, so the Boggart was changed into other members of the family rather than something humorous.
(Rose Growth)-
Description: Causes rosebushes grow at an unusually fast pace.
Seen/Mentioned: Harry Potter Trading Card Game
Notes: This spell may be related to Herbivicus.
(Rowboat spell)-
Description: A spell invented by Hagrid which propels row boats to a pre-set destination.
Seen/mentioned: Hagrid used the spell on the row-boats at Hogwarts, to transport the First years from Hogsmeade Station to the Boathouse. It may also have been the spell that he used to propel the row-boat that he used to take Harry from the Hut-on-the-Rock back to the mainland in 1991.
Description: This spell transforms the victim's ears into kumquats.
Seen/Mentioned: In 1995, Luna Lovegood read The Quibbler upside down in order to reveal the secret charm, written in Ancient Runes.
