Etym: Several Web sites (including an earlier version of this one, mea culpa) have given this as the root of abracadabra, originating as a Kabalistic term. Instead, it appears that abracadabra comes from Abraxas via Gnostic occultism, and I haven't been able to find anything on the origins of avada kedavra.

Hebridean Black: A type of dragon native to the British Isles.
Hedwig: Harry's owl, named after someone he read about in A History of Magic.
Etym: Stated by Rowling to be a medieval saint, which would be St. Hedwig of Andechs. Another possibility is the devout but not canonized medieval woman who was crowned "king" of Poland at the age of 9, strongly supported religion and scholarship, and caused the restoration of the university of Kraków, which became the Jagiellonian University. (Here's the English root page.)
Helga Hufflepuff: Etym: From Norse, meaning "holy". Also an alternate name for St. Olga (890-969), the first recorded female ruler in Russa, the first Russian royal to adopt Christianity, and the first Russian Orthodox saint.
Hengist of Woodcroft (PS ch. 6): Was featured on a Famous Witches and Wizards trading card. Might be an actual historical person, but I haven't found any info on him.

Etym: From the medieval given name Hicke, a form of Richard, whose etymology is uncertain; may be riic "ruler" + heard "hard".
hinkypunk: A one-legged creature which lures travelers to their death in bogs.
Etym: Usually spelled Hinky-Punk, this is a local equivalent to the will-o'-the-wisp on the Somerset-Devon border.
hippogriff: A mythical creature with the head, wings, and legs of an eagle and the hindquarters of a horse. In these books, a proud and demanding creature that requires a person to show respect before they can approach it.

Etym: -meade in English placenames refers to a piece of grassland; thus, it's the meadow near Hogwarts. Interesting that the school appears to have preceded the village (unless both were named after some other local feature).
Hogwarts: The school for young wizards in the British Isles, housed in a massive castle with 142 shifting staircases, living paintings, numerous ghosts, and pretty much everything else that would have made your school the least bit interesting.

holly: Shrubs and trees of the genus Ilex, reputed to have protective powers. Harry's wand probably was made with English holly (I. aquifolium).
Etym: Rowling has given her reason for using it as its association with life and also with the word holy. Unfortunately, the second part is folk etymology; the word holly goes back to an Indo-European stem meaning "to prick". (Hollyhock, on the other hand, evolved from holy hock.)
Home Life and Social Habits of British Muggles: The textbook for the Muggle Studies class.
Homorphus Charm: The spell with which Lockhart claims to have cured the Wagga Wagga Werewolf. He probably made it up-- it appears the Wolfsbane Potion is the only effective countermeasure.

Etym: No info; also invented?

Horseback Head-Juggling: Another pastime of the Headless Hunt.
house-elf: A magical creature, bound to a specific wizard family or place, which does housekeeping tasks. If a house-elf's employer hands a piece of clothing to them, the elf is considered dismissed.
House-elves are based on brownies, mostly benevolent spirits said to inhabit particular houses or farmsteads and do chores when no one is looking. One can leave bread or a bowl of milk or cream out for the brownie to show thanks, but making any more extravagant gifts will offend it, which will turn to mischief. If a suit of clothes is made for a brownie, it will put them on and disappear.
House-Elf Liberation Front: Hermione's current effort to better the conditions of house-elves.
Hover Charm: A spell used to make something float in the air. Apparently detectable from a distance (unless someone from the Improper Use of Magic Office just happened to be nearby).

Hufflepuff, Helga: One of the four founders of Hogwarts.
Etym: See below.

Badge: Or, a brock rampant reguardant, at best guess, anyway. House colors are supposed to be black and gold. The house ghost is the Fat Friar, and the head of the house is Professor Sprout.
See "In Defense of Hufflepuff" for more on the house philosophy.
Etym: Invented; along the lines of "huff and puff".

Improper Use of Magic Office: The arm of the Ministry of Magic which, among other things, keeps tabs on any students who try to use magic outside of school.
incantations: The verbal components of spells. Incantations come in a variety of languages. Oddly, modern-language spells which contain verbs are in the imperative (the command form) but the Latin ones are in the indicative (that is, descriptive of action). There may be a deep reason for this, but it's probably just because Rowling was never forced to take Latin. I was, and by golly I'm going to get some use out of it. Imperative forms are provided for the curious.
Incendio: An incantation to start a fire.
Etym: Latin, "I set fire to". Imperative: incendere.

International Association of Quidditch: The organization which sanctions the Quidditch World Cup, akin to FIFA.
International Ban on Dueling: The exact nature of the ban has not been explained, but since Lockhart was allowed to have a go at starting a dueling club, it's either very recent, or not a total ban, or the UK is not a signatory to it. We know for certain that Transylvania is not.
International Confederation of Warlocks: Some sort of multinational professional association.
International Federation of Warlocks: Probably a typo for the International Confederation of Warlocks, or vice versa.

Etym: From the Middle English given name Jenkin, a diminutive of John.
Jigger, Arsenius (PS ch. 5): Author of Magical Drafts and Potions.
Etym: 1.5 fluid ounces; a measurement used for alcoholic drinks. So, a poisoned drink. Jeez, it's like everything associated with potions has to be evil and nasty.
Joey Jenkins [Joseph]:
Etym: Joseph is from the Hebrew for "may Jehovah add (children)". On the other hand, Joey is a semi-archaic slang term for a clown.
Johnson, Angelina (PS ch. 12): A Chaser on the Gryffindor Quidditch team, 2 years ahead of Harry.
Etym: Patronymic form of John, which is from the Hebrew name Johanan "Jehovah has favored".

Karkaroff, Igor: The headmaster of Durmstrang and a former Death Eater, now on the run from Voldemort.
Etym: Couldn't find anything on this name, but might be invented from the Russian stem karka- "to caw, to predict the worst". Another outside possibility is Finnish karkuri "deserter, runaway".
Katie Bell [Katherine]:
Etym: St. Katherine or Catherine of Alexandria was a scholarly woman who was imprisoned for converting the wife and soldiers of the emperor Maxentius. He is said to then have dispatched his philosophers to convince her by logical arguments to denounce her faith, only to find that she instead converted them. Later she was martyred, and a particular instrument of torture associated with this is known as "St. Katherine's Wheel". The etymology of this name is unknown.

Knut: 1/493 of a Galleon, 1/29 of a Sickle.
Etym: Not sure, maybe just a variation of nut, the coins being brownish and all.
Krum, Viktor: The Seeker on the Bulgarian national Quidditch team, and the Triwizard Champion for Durmstrang. Wand: 10.25", rigid, hornbeam and dragon heartstring.
Etym: This was the name of a Bulgarian khan who died in 814, who developed the first rudiments of state organization there and was able to threaten the Byzantine Empire toward the end of his reign. Krumm, German for "crooked, bent, winding, twisted" is mentioned on other HP Web sites, but this seems an unlikely source to me.
Kwikspell: A correspondence course in basic magic that Filch apparently tried.

Leaky Cauldron, The: A wizards' pub located somewhere in London, along Charing Cross Road; the primary entrance to Diagon Alley.

Licorice Wands: A wizard candy, undoubtedly very tasty if you happen to like licorice.
Lily Potter: Etym: As a personal name, probably derives from a pet form of Elizabeth. In the plant world, anything in the genus Lilium. Different types of lily have different meanings; if a specific one is intended, it's probably "purity and sweetness", the white lily. Outside possibilities are "majesty", for the imperial lily, or "return of happiness", the lily of the valley.
lionfish: Several species of fish of the family Scorpaenidae. The spines, which contain a mild venom, are a basic potion-making supply.
Lisa Turpin: Etym: Another nickname from Elizabeth, which is from Hebrew Elisheba, "my God (is) satisfaction".

Little Whinging: The town in Surrey in which the Dursleys live. Does not appear to be a real town.
Lockhart, Gilderoy: A best-selling author, honorary member of the Dark Force Defense League, five-time winner of the Witch Weekly Most Charming Smile Award, and the Defense Against the Dark Arts teacher in Harry's second year. Owing to a bungled Memory Charm, he is now confined to St. Mungo's Hospital, and unlikely to write anything more unless it's Psessions with Psychologists.

Lovegoods: Acquaintances of the Weasley family who arrived at the Quidditch World Cup site a week before them.
Etym: No etymology.
Lucius Malfoy: Etym: From Latin lux, light; possibly intended as a reference to Lucifer, "light-bearer". The name of three popes, including the patron saint of Copenhagen, who succeeded St. Cornelius and continued his policies... does this mean we'll be seeing a new Minister of Magic? EB also gives this as an obsolete form of luscious, but let's not go there.
Ludo (Ludovic) Bagman:
Etym: Ludo is a game similar to pachisi/parcheesi. The word is Latin for "I play".
Lumos: An incantation to make one's wand glow.

Lupin was also one of James Potter's close friends during their school days.
Etym: A variation on lupine.
Lynch, Aidan (GoF ch. 8): The Seeker on the Irish national Quidditch team.

Etym: HH has three possibilities, the most interesting being an anglicization of Mac an Mhaoir, "son of the steward, keeper". "The principal Irish family of this name held the hereditary post of Keeper of the Book of Armagh at Ballymoyer (Gaelic Baile an Mhaoir `town of the keeper')."
Madcap Magic for Wacky Warlocks: A book in the Hogwarts library.

Malfoy, Draco: A Slytherin, the same year as Harry, who generously offered to introduce Harry to the "in" crowd and has not yet gotten over being snubbed. In Harry's second year and later, the Seeker for the Slytherin Quidditch team.
Etym: Stated by Rowling to be an invented name, from the French mal + foy or foi. Could be taken to mean "bad faith" as in a lack of faith or a false promise, or "faith in evil". We've certainly seen both out of the Malfoys by now.
Malfoy, Lucius: A Death Eater of exalted lineage who has ascended the steps of societal power, taking hold of the scepter of leadership for the pure-blood faction, only to be smacked by the wet haddock of Voldemort's return and fall into the slimy canal of embarrassment at not being immediately thrilled at his former master's return.
Etym: See above.

Etym: See above.
Malkin, Madam (PS ch. 5): Proprietor of Robes for All Occasions in Diagon Alley.
Etym: As a surname, derived either from the medieval female given name Malle, or the Yiddish name Malke, from the Hebrew word malka "queen". OED also gives it as a name for a woman of the lower classes in various proverbial expressions; the name of a female spectre or demon; dialectual name for a cat; or an effeminate man. If I had to guess, I'd go with the female spectre.
mandrake: In these books, a plant which resembles a humanoid with a normal-looking plant growing out of its head. The scream of a mature mandrake can kill, while that of a young one will still stun a person. Mandrakes can be used to restore a person who has been paralyzed by a basilisk.

Etym: Probably invented as a cognate to "maximum".
McDonald, Natalie: A Gryffindor, 3 years behind Harry.

McGonagall, Minerva: Head of Gryffindor House, and the Transfiguration instructor.
Etym: Patronymic from the name Congal, composed of the Old Celtic words for "high" and "valor", appropriate for a Gryffindor. However, the professor is actually named for a Scottish poet reputed to be the worst ever to, er, grace the English language.
McGuffin, Jim (PS ch. 6): A TV weatherman.
Etym: Name etymology is probably not relevant. The name was used as a term by Alfred Hitchcock to mean an object that is significant to a plot. Okay, that's probably not relevant here either.
McKinnon (PS ch. 4): The last name of a wizard couple killed by Voldemort.
Etym: Anglicized form of Mac Fhionghuin, from the name meaning "fair born" or "beloved son".

Mimsy-Porpington, Sir Nicholas de: Aka Nearly Headless Nick, the house ghost of Gryffindor. He celebrated his 500th deathday on Halloween, 1992. If this count includes the shift to the Gregorian calendar, it means he died on October 20th or 21st, 1492.
Etym: Mimsy was a word invented by Lewis Carroll for his poem "Jabberwocky", and has been defined as "prim, prudish, contemptible". No idea about Porpington.
