Accio
The Summoning Charm. It attracts an object to the caster. Knowing the object's general location is vital. The necessary incantation is "Accio", along with a firm mental picture of the object in question. When the object is out of sight, it is usually supplemented by the name of the requested object (e.g. "Accio Broomstick") for easier visualization. It is likely to have come frome the Latin "Accipere, to accept". The spell may also be used in conjunction with the name of the owner of the object, to clearly specify the object that the caster wishes to retrieve. (e.g. “Accio Rosmerta’s Brooms!)
Aguamenti
The charm sends a stream of water from the tip of the wand. The prefix is derived from the Latin word, aqua, meaning "water". The water may come out in various amounts. Once, Harry performed the spell to put out the fire on Hagrid's hut (must have been a huge jet of pounding water) and another time to fill a goblet (must have been a gentle stream of water). This shows that the volume of water conjured from Aguamenti can be controlled.
Alohomora
This spell is used to open a locked door or window. Pointing a wand at a door and saying "Alohomora" will unlock the door. Probably a compressed form of Latin "Alo hoc mora" = English "I raise this barrier." This spell can also open doors which have been magically sealed with the Colloportus spell. Doors can be magically sealed with sufficiently advanced spells so that Alohomora cannot open them.
Anapneo
This spell was used to dislodge a pheasant from Marcus Belby's throat in Harry Potter and the Half-Blood Prince. Appears to be an Anti-Choking spell of some sort. The word is Greek and means "I breathe" so this spell is seemingly used to make or help someone breathe. The word also shares its root with Apnea, a disorder in which one's breathing becomes irregular during sleep; the prefix an- is an analog to non- or dis-.
Aparecium
This spell makes invisible ink and perhaps invisible items in general appear. First used in CoS when Hermione Granger tried to make something appear in Tom Riddle's diary.
Avis
Makes birds fly out of the wand of the spellcaster. Used in GoF by Mr Ollivander to test Viktor Krum's wand.
The Banishing Charm*
The opposite of the Summoning Charm. It causes the targeted object to be thrown away from the caster, but it requires good aim. It is possible that this is a nonverbal spell, because it was used by students as they talked with each-other. First seen in a charms lesson in GoF. Possibly used by Severus Snape to banish Harry's wand in Harry Potter and the Half-Blood Prince.
Bubblehead Charm*
Puts a large bubble of air around the head of the user. Used as a magical equivalent of a breathing set. Cedric Diggory and Fleur Delacour used this underwater in the second task of the Triwizard Championship in GoF. It is also used by many Hogwarts students when walking through the hallways in Harry Potter and the Order of the Phoenix, because of the bad smells caused by the various pranks on Dolores Umbridge.
Chain Spell*
Creates a gold chain. Used nonverbally by Marvolo Gaunt in Harry Potter and the Half-Blood Prince to restrain Merope.
Cheering Charm*
Incantation unknown. Causes the person whom the spell was cast upon to become happy and contented, though heavy-handedness with the spell may cause the person to break into an uncontrollable laughing fit. Invented by Felix Summerbee (1447–1508). First seen in PoA.
Colloportus
This spell will magically lock a door, preventing it from being opened for a presumably limited amount of time. It is easily countered by Alohomora, however. The word is a combination of "colligare" (Latin for "bind together") and "porta" (Latin for "door").
Deletrius
Erases images. First seen in GoF when Amos Diggory gets rid of the echo of the Dark Mark from Harry's wand.
Disillusionment Charm*
Causes the target to become able to change color as camouflage, like chameleons, flatfish and octopuses can. Alastor Moody uses it on Harry Potter in Harry Potter and the Order of the Phoenix.
Diffindo
Severs the target. In GoF when Harry urgently wants to talk to Cedric Diggory he casts this spell to rip his bag, thus delaying him for class.
Engorgio
Makes something grow larger.
Ennervate
The counterspell to the Stunning Spell. May be more than a counterspell, there have been instances when it is used to help people regain consciousness who haven't been Stupefied. The etymological root of this spell is from Latin for "to add nerve"; hence the English word "ennervate". If spelled with one "n," however, it has the opposite meaning - to weaken, rather than invigorate (though a post hoc explanation could be fashioned to claim that it is the stunning spell that is weakened by this spell, in which case the etymology would fit).
Episkey
Used in GoF after the first task of the Triwizard Tournament. Nymphadora Tonks uses this spell in Harry Potter and the Half-Blood Prince to fix Harry's broken nose, later Harry uses it to heal a fat lip. This leads the reader to the conclusion that it is a spell to heal minor injuries (assuming you consider a broken nose a mild injury). The word comes from the Greek "episkevi" ("åðéóêåõÞ"), which means "repair". J. K. Rowling writes in Harry Potter and the Half-Blood Prince, Harry's knowledge tells him that 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.
Evanesco
Makes something vanish.
Expecto Patronum
This spell conjures a Patronus, a silvery phantom shape, usually that of an animal, which is the embodiment of the positive thoughts or character/personality/desire of the caster. A Patronus will drive away Dementors and Lethifolds. A patronus "is an anti-Dark device, which makes it highly resilient to Dark wizards; it is not hindered by physical barriers; each Patronus is unique and distinctive; nobody else can conjure another person's Patronus." In order for the spell to work, the person must concentrate on a happy memory, which is especially difficult in the presence of a Dementor. Latin "expecto patronum" means "I expect (welcome is the literal translation) a guardian," although the Latin phrase is deep in ambiguity: ex + pecto would mean from the chest (prehaps "from the heart", implying that the Patronus is the heart's guardian), and patronum is an archaic word for father, implying that another interpretation is "I expect my father.", which could be related to the fact that Harry's patronus takes his father's animagus form. If the thought is not focused on strongly enough, a silver glow or mist appears, which does little but slow down a Dementor for a moment. Members of the Order of the Phoenix are taught by Dumbledore how to send messages through their Patronuses, and they are the only ones in the world who know this special technique, as it is Dumbledore who came up with this ingenious idea.
Expelliarmus
The disarming spell. This spell is used to disarm another wizard, typically by causing the victim's wand to fly out of reach. It also throws the wizard backwards a few feet when enough power is placed behind it. As demonstrated in the novel PoA, simultaneous use of this spell by multiple people on a single wizard can throw the wizard back more powerfully.
Featherweight Charm*
Makes something lightweight. Harry contemplates using this in PoA to lighten his trunk so that he can carry it by broom to Hogwarts. Before he uses it, however, he accidentally summons the Knight Bus.
Ferula
Creates a splint. The name ferula comes from Latin, and means "carrier" or "vehicle".
Fidelius Charm*
This complex charm enables secret information to be hidden within a single living soul of someone 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. It originates from the Latin word "fidelis", which means "faithful" or "trusting".
So far, there have been only two uses of the Fidelius Charm in the Harry Potter series:
• In PoA, it is explained that when Harry was an infant, he and his parents, Lily and James, were hidden from Lord Voldemort by this charm. They initially selected Sirius Black to be their Secret-Keeper, but Black recommended that they choose Peter Pettigrew instead. When they did, Pettigrew betrayed them to Voldemort (and framed Sirius for doing so, as well as for Pettigrew's own murder).
• In Harry Potter and the Order of the Phoenix we are told the charm is also used to hide the headquarters for the Order of the Phoenix; Albus Dumbledore is the Secret-Keeper, and is apparently able to use a letter to reveal the information to Harry. This implies that a direct, personal act is not required to bring a new person into the secret. It's not confirmed, but now that Dumbledore is dead, perhaps the Incantation has vanished.
Finite Incantatem
Stops the effects of spells. Snape uses it in CoS to restore order in the Dueling Club. Lupin uses the short form "Finite" in OotP also.
Flagrate
With this spell, the caster's wand can leave fiery marks of the caster's choosing. From the Latin root flagrant or flagrare, meaning blazing.
Flame-Freezing Charm*
A charm mentioned in the first chapter of PoA as used by witches and wizards during medieval burnings. Flames are caused to be harmless, creating only a gentle, tickling sensation instead of burns. This spell was possibly used in Harry Potter and the Half-Blood Prince by Dumbledore to seemingly set fire to Tom Riddle's old wardrobe whilst causing no physical damage.
Homomorphus Charm*
Used by Gilderoy Lockhart, according to one of his books, to force a Werewolf to take its human form (CoS). Since the events in his books were actually the works of other wizards, it can be assumed that this is a real charm and is considered to be very complex. It may also have been used by Sirius Black and Remus Lupin in PoA, nonverbally, to force Peter Pettigrew to assume his human form.
Imperturbable Charm*
Makes objects such as doors impenetrable (by everything, including sounds and objects). Used by Mrs. Weasley in Harry Potter and the Order of the Phoenix, when she used the Imperturbable Charm on the door of the room where an Order of the Phoenix meeting was going on, to prevent her sons, Fred and George, from eavesdropping. This spell is also used in GoF by Hermione to trap Rita Skeeter in beetle form.
Impervius
Known as the Impervius Charm, this spell makes something repel water.
Incendio
Produces fire.
Liberacorpus
Non-verbal (keep in mind all spells may be non-verbal) counter-jinx for Levicorpus. Emits a flash of light and frees the target of being hoisted by their ankle. "Libera" from "Liberare" means "to set free" and "corpus" means "body", in Latin. Though this is the Half-Blood Prince's creation, it can be speculated that Tonks used this spell to free Harry from Petrificus Totalus inside the Hogwarts Express, as the spell she used also emitted a flash of light.
Locomotor
The target of the spell, which is said after "Locomotor", rises in the air and can be moved around by the wizard. (e.g. "Locomotor Trunk" ). "Locomotor" can be interpreted from "locus" (place) and "movere" (movi, motum: to move) "to move to another place".
Lumos
This spell creates a narrow beam of light that shines from the wand's tip, like a torch. It comes from the Latin term lumen, meaning a light. Despite it being rudimentary, the charm is used countless times throughout the series. Different versions of this spell used in the movie are Lumos Solem and Lumos Maxima, and the way the light is emitted is different too - in the books, it is described as 'a beam of light', but in the PoA movie, Snape's application of Lumos created a sphere of light. It may also cause the wand tip to burst into flames, as used in Harry Potter and the Order of the Phoenix to destroy a secret message from Albus Dumbledore.
Memory Charm
Wipes all or part of a person's memory. While always referred to as the "Memory Charm", the actual incantation for this spell is Obliviate or Oblivious.
Mobiliarbus
This spell was used by Hermione to move a tree. It is combined from the Latin words "mobilis", movable, and "arbus", tree.
Muffliato
This spell fills peoples' ears with an unidentifiable buzzing, to keep them from hearing nearby conversations. It was created by the Half-Blood Prince.
Nox
This spell turns off the light which is activated by the Lumos spell, and may be used to turn out other lights (like the Put-Outer). Nox is Latin and means "night".
Orchideous
Makes a bouquet of flowers appear out of the wand.
"Pack"*
This spell literally packs a person's trunk for them – the neatness of the "packing" seems to be dependent upon the caster's experience. Nymphadora Tonks performs the spell, once with the word "Pack" and again with just a flick of the wand but says her mother is far better at this sort of household spell. It may be that "pack" is not the actual incantation, and that Tonks was finishing her sentence while performing a non-verbal spell.
"Point Me"
The Four-Point Spell causes the caster's wand tip to point to the north cardinal point, acting like a compass. It only points north.
Portus
The spell which turns an object into a Portkey, a device which transports the toucher to a desired destination. Latin portus means doorway.
Priori Incantato
Latin for "previous incantation". Makes a shadowy image of the effect of the last spell cast by a wand emerge from its tip. This is called an echo of the spell. The nature of the echo depends on the original spell. The echo of a conjuring spell, for example, is the object conjured. However, the echo of the Cruciatus curse is the screaming of the victim, while the echo of an Avada Kedavra curse is the corpse of its victim. When two wands that share the same magical core are forced to engage in battle, a more powerful reverse spell effect called Priori Incantatem takes place – that is, the plural of Priori Incantato. One of the wands will be forced by the other to gradually regurgitate shadows of all the spells it has cast, in reverse chronological order. The echos themselves are stronger as well. For example, the echo of the Avada Kedavra curse is not just an image of a corpse, but a temporary ghost-like representation of the victim which is capable of at least limited communication with living beings present.
Protean Charm*
Causes copies of an object to be remotely affected by changes made to the original. First used in Harry Potter and the Order of the Phoenix when Hermione puts this 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 D.A. (Dumbledore's Army) meeting appears as it is subject to change. It is used to avoid drawing attention and to warn people without them having to meet and look suspicious, avoiding Professor Umbridge's suspicions. So that people know that the date has changed the coin becomes hot, alerting the owner to look at the Galleon. The Protean Charm is an NEWT standard charm according to Terry Boot, who is incredulous that Hermione can perform it already.
The charm's name comes from Proteus, a shape-shifting god in Greek mythology.
Hermione later tells Harry that she based the idea on Voldemort making the Dark Marks of his Death Eaters become warm, telling them that they must come to him. Hermione jokes that she thought it better to use coins rather than their members' skin.
Protego
The Shield Charm causes minor jinxes to rebound upon the attacker. Latin protego means "I cover".
Quietus
Makes a magically magnified voice return to normal.
Reducio
Makes something smaller. Mad-Eye Moody uses it in GoF. Countercharm to Engorgio. (Whether or not Reducio can also be used by itself, rather than countering Engorgio is unknown. If possible it would shrink normal sized items into minature versions of themselves. References in CoS by Arthur Weasley to "shrinking doorkeys" would make this seem likely.)
Rennervate
This spell appears to rouse an unconscious person.
Reparo
Used to repair objects. Used countless times throughout the books. First seen in the 1st book, used by Hermione Granger to fix Harry's glasses, as "oculus reparo".
Rictusempra
Tickling Charm. The incantation comes from the Latin words risus ("laughter" or "ridule") and semper ("always") - "laughter always".
Riddikulus
A spell used when fighting a Boggart, "Riddikulus" forces the Boggart to take the appearance of what the spellcaster is thinking as amusing so that the laughter will weaken it. First seen in PoA, the Latin word "riddiculus" means "exciting laughter" or simply "laughter". It is pronounced with a hard "c".
Scourgify
Used to clean something.
Silencio
The Silencing Charm. Makes something silent (a bullfrog and raven were used as examples in the book). Silencio means 'Quiet' in Spanish and Portuguese and has its origins in the Latin word "silentium".
Sonorus
Magnifies the spellcaster's voice.
Specialis Revelio
Causes something to show its hidden secrets.
Tergeo
A siphoning spell. Hermione Granger uses this spell in Harry Potter and the Half-Blood Prince to siphon blood from Harry's face, and it's later used to siphon ink, leading the reader to the conclusion it can siphon any liquid. In Latin, "tergere" means "to clean" or "to wipe off/wipe dry."
Waddiwasi
Used by Remus Lupin in PoA to expel a wad of chewing gum from the key hole Peeves put in and launch it up Peeves's nose. Latin "vadi vasi" roughly means rush (away) stuff. (The Latin letter V is pronounced like the English letter W.) Specific function not clear. Possibly launches a small "wad" of any sort in the direction desired by the caster.
Wingardium Leviosa
This spell levitates objects. First seen in Professor Flitwick's class, when the first years practice the spell with feathers. In the movie, it is used by saying "Wingardium Leviosa!" while making a "swish and flick" movement with the wand. "Wingardium" is a combination of the English word "wing" and the Latin word "arduus" (meaning "steep") and "leviosa", which contains the Latin word "levare" (meaning "ease, lift, pick up").
OTHER
Dissendium
Causes the statue of the humpbacked witch hiding the secret passage to Honeydukes to open up. First seen in PoA. This may not be a spell, but a magical password like "Mimbulus Mimbletonia" (once a password for the Fat Lady)
*Incantationless Spells and Spells With No Known Incantation
Incantationless Spells are spells cast by the caster in a nonverbal fashion. The benefit of this is to become faster in a duel and to catch an opponent off-guard. Such spells take a lot of concentration and a lot of practice of your mind. Note: Some of these spells may in fact have incantations, but no incantation is known to exist for these spells
The Summoning Charm. It attracts an object to the caster. Knowing the object's general location is vital. The necessary incantation is "Accio", along with a firm mental picture of the object in question. When the object is out of sight, it is usually supplemented by the name of the requested object (e.g. "Accio Broomstick") for easier visualization. It is likely to have come frome the Latin "Accipere, to accept". The spell may also be used in conjunction with the name of the owner of the object, to clearly specify the object that the caster wishes to retrieve. (e.g. “Accio Rosmerta’s Brooms!)
Aguamenti
The charm sends a stream of water from the tip of the wand. The prefix is derived from the Latin word, aqua, meaning "water". The water may come out in various amounts. Once, Harry performed the spell to put out the fire on Hagrid's hut (must have been a huge jet of pounding water) and another time to fill a goblet (must have been a gentle stream of water). This shows that the volume of water conjured from Aguamenti can be controlled.
Alohomora
This spell is used to open a locked door or window. Pointing a wand at a door and saying "Alohomora" will unlock the door. Probably a compressed form of Latin "Alo hoc mora" = English "I raise this barrier." This spell can also open doors which have been magically sealed with the Colloportus spell. Doors can be magically sealed with sufficiently advanced spells so that Alohomora cannot open them.
Anapneo
This spell was used to dislodge a pheasant from Marcus Belby's throat in Harry Potter and the Half-Blood Prince. Appears to be an Anti-Choking spell of some sort.

Causes copies of an object to be remotely affected by changes made to the original. First used in Harry Potter and the Order of the Phoenix when Hermione puts this 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 D.A. (Dumbledore's Army) meeting appears as it is subject to change. It is used to avoid drawing attention and to warn people without them having to meet and look suspicious, avoiding Professor Umbridge's suspicions. So that people know that the date has changed the coin becomes hot, alerting the owner to look at the Galleon. The Protean Charm is an NEWT standard charm according to Terry Boot, who is incredulous that Hermione can perform it already.
The charm's name comes from Proteus, a shape-shifting god in Greek mythology.
Hermione later tells Harry that she based the idea on Voldemort making the Dark Marks of his Death Eaters become warm, telling them that they must come to him. Hermione jokes that she thought it better to use coins rather than their members' skin.
Protego
The Shield Charm causes minor jinxes to rebound upon the attacker. Latin protego means "I cover".
Quietus
Makes a magically magnified voice return to normal.
Reducio
Makes something smaller. Mad-Eye Moody uses it in GoF. Countercharm to Engorgio. (Whether or not Reducio can also be used by itself, rather than countering Engorgio is unknown. If possible it would shrink normal sized items into minature versions of themselves. References in CoS by Arthur Weasley to "shrinking doorkeys" would make this seem likely.)
Rennervate
This spell appears to rouse an unconscious person.
Reparo
Used to repair objects. Used countless times throughout the books. First seen in the 1st book, used by Hermione Granger to fix Harry's glasses, as "oculus reparo".
Rictusempra
Tickling Charm. The incantation comes from the Latin words risus ("laughter" or "ridule") and semper ("always") - "laughter always".
Riddikulus
A spell used when fighting a Boggart, "Riddikulus" forces the Boggart to take the appearance of what the spellcaster is thinking as amusing so that the laughter will weaken it. First seen in PoA, the Latin word "riddiculus" means "exciting laughter" or simply "laughter". It is pronounced with a hard "c".
Scourgify
Used to clean something.
Silencio
The Silencing Charm. Makes something silent (a bullfrog and raven were used as examples in the book). Silencio means 'Quiet' in Spanish and Portuguese and has its origins in the Latin word "silentium".
Sonorus
Magnifies the spellcaster's voice.
Specialis Revelio
Causes something to show its hidden secrets.
Tergeo
A siphoning spell. Hermione Granger uses this spell in Harry Potter and the Half-Blood Prince to siphon blood from Harry's face, and it's later used to siphon ink, leading the reader to the conclusion it can siphon any liquid. In Latin, "tergere" means "to clean" or "to wipe off/wipe dry."
Waddiwasi
Used by Remus Lupin in PoA to expel a wad of chewing gum from the key hole Peeves put in and launch it up Peeves's nose. Latin "vadi vasi" roughly means rush (away) stuff. (The Latin letter V is pronounced like the English letter W.) Specific function not clear. Possibly launches a small "wad" of any sort in the direction desired by the caster.
Wingardium Leviosa
This spell levitates objects. First seen in Professor Flitwick's class, when the first years practice the spell with feathers. In the movie, it is used by saying "Wingardium Leviosa!" while making a "swish and flick" movement with the wand. "Wingardium" is a combination of the English word "wing" and the Latin word "arduus" (meaning "steep") and "leviosa", which contains the Latin word "levare" (meaning "ease, lift, pick up").
OTHER
Dissendium
Causes the statue of the humpbacked witch hiding the secret passage to Honeydukes to open up. First seen in PoA. This may not be a spell, but a magical password like "Mimbulus Mimbletonia" (once a password for the Fat Lady)
*Incantationless Spells and Spells With No Known Incantation
Incantationless Spells are spells cast by the caster in a nonverbal fashion. The benefit of this is to become faster in a duel and to catch an opponent off-guard. Such spells take a lot of concentration and a lot of practice of your mind. Note: Some of these spells may in fact have incantations, but no incantation is known to exist for these spells
