Parseltongue is the language of serpents (as well as other magical serpent-based creatures, like the Runespoor and Basilisk) and those who can converse with them. An individual who can speak parseltongue is known as a Parselmouth. It is a very uncommon skill, and was known to be an almost exclusively hereditary trait. Not counting Herpo the Foul, who predated him by several ceturies, nearly all known parselmouths are descended from Salazar Slytherin, with Harry Potter and Herpo the Foul, being two notable exceptions (although Harry Potter gained his ability as a Parselmouth in an unorthodox manner).
Parseltongue is, when spoken, a hissing sound, similar to that of a snake; as such, normal people cannot understand it (one known exception being Dumbledore). Apart from merely communicating with serpentine lifeforms, Parselmouths also seem able to influence the will of serpents to a certain extent. Aside from serpent-based creatures, Parselmouths can communicate with each other with the language, as Harry understood Tom Riddle's commands to the Serpent of Slytherin, and the House of Gaunt communicate with each other almost exclusively in Parseltongue. While inherited, Parseltongue usually requires the speaker to face a snake-based creature or object shaped like a snake (e.g. a carving); more proficient speakers may be able to speak it at will, as the Gaunt family was very proficient in the language — enough so for Morfin to speak to Bob Ogden with it, while Voldemort could speak to the Statue of Slytherin to release the basilisk.
- "The boy can talk to snakes, Dumbledore, and you still think he's trustworthy?"
- —Cornelius Fudge's prejudice against Parselmouths[src]
An unknown member of the Dark Force Defence League once stated when asked regarding the matter by Rita Skeeter — "Personally, I would be highly suspicious of anybody who could converse with snakes, as serpents are often used in the worst kinds of Dark Magic, and are historically associated with evildoers."
Harry Potter as a Parselmouth
Harry was not consciously aware of his ability to speak Parseltongue until 1992; he was pitted against Draco Malfoy in the Duelling Club and was able to communicate with the snake Draco conjured to attack him, telling it not to attack Justin Finch-Fletchley. This caused hysteria among his fellow students because graffiti on the walls of Hogwarts Castle foretold that the Heir of Slytherin would open the Chamber of Secrets, unleashing a monster that would attack the school's Muggle-born students. The Heir of Slytherin was in fact Voldemort, but Harry was able to gain access to the Chamber by speaking the password in Parseltongue, and subsequently killed the basilisk within. It was shortly after this incident that Harry learned how he acquired the ability.
When the wizarding world discovered Harry's ability to speak Parseltongue, courtesy of Rita Skeeter, people began to doubt his words, as Cornelius Fudge refused to believe Harry's claim of Voldemort's rebirth partially due to being prejudiced to Harry's ability to speak the language.
Harry also used his skill in Parseltongue to open Salazar Slytherin's Locket. When Harry, Ron Weasley, and Hermione Granger returned to Hogwarts to search for Rowena Ravenclaw's Diadem, Ron managed a weak imitation of Parseltongue to re-open the Chamber of Secrets so that he and Hermione could fetch basilisk fangs, which Hermione used to destroy Helga Hufflepuff's Cup.
Harry Potter never tried to use again the ability during the next twenty-two years, but in 2020, despite his previous belief that the ability was lost forever to him, Harry had somehow regained the ability to speak and understand Parseltongue again if he truly ever lost it in the first place. While initially reluctant to do so and only after Hermione insisted that he had to try, Harry successfully spoke Parseltongue to open the enchanted room of Delphini while searching for his missing son, Albus Potter. Later, in order to impersonate the Dark Witch's father, Lord Voldemort, Harry again used his ability to speak Parseltongue.

Unconfirmed potential Parselmouths
The ability to speak Parseltongue being known to be hereditary, the blood relatives of known Parselmouths are potentially Parselmouths themselves.
Other instances of Parseltongue
People who were not Parselmouths but were able to speak or understand Parseltongue through various means.
- Ginny Weasley was able to speak Parseltongue while she was possessed by Tom Riddle's Diary, which enabled her to open the Chamber of Secrets.
- Ron Weasley was also able to open the Chamber of Secrets during the Battle of Hogwarts by repeating a fragment of Parseltongue he had heard Harry Potter use to open Salazar Slytherin's Locket, though it took him several tries to make it work.
- Albus Dumbledore could understand Parseltongue and repeat sentences in it verbatim; he may have been able to speak it in full, although this is unconfirmed.
- Bathilda Bagshot's carcass spoke in Parseltongue while it was occupied by Nagini.
- Isolt Sayre, a direct descendant of Salazar Slytherin, was able to understand a Horned Serpent which she regularly visited but as of known never spoke Parseltongue herself.
Behind the scenes
- J. K. Rowling has stated that she took the name Parselmouth from an "old word for someone who has a problem with the mouth, like a hare lip".
- When Harry Potter and Hermione Granger went to Godric's Hollow in 1997, Nagini (inside the corpse of Bathilda Bagshot) tells Harry to "Come!" from the next room in Parseltongue. In reaction, Hermione jumps and clutches Harry's arm, and the two of them obey the command. It is unknown how Hermione seemed to understand this command, though it could be that she did not hear it well, and merely followed Harry. She could also have been frightened by the hissing sound she heard and then followed Harry.
- In the Philosopher's Stone film, Harry converses with a Burmese python, rather than a Boa Constrictor.
- Whenever it was spoken in the films, Parseltongue went untranslated except for one scene in Harry Potter and the Deathly Hallows: Part 2 when Voldemort was speaking to Nagini, where it was given subtitles. It was also heard in English in the first film when Harry was talking in the Zoo.
- In the films, Parseltongue is depicted as sounding like a sibilant-filled language with readily discernible phonemes created by Dr Francis Nolan (as listed in the credits for Harry Potter and the Deathly Hallows). In the novels, it is only ever described as a low hissing noise, easily missed by non-Parselmouths — a far cry from the rather loud versions from the films.
- In the last two films, as Harry draws near a Horcrux he can hear, in addition to a whining noise, a faint voice which seems to speak in Parseltongue.
- It is possible that Parseltongue comes in variants for different languages, rather than being understood as the language spoken by the Parselmouth. The boa constrictor that Harry Potter converses with at the Zoo uses the Portuguese word amigo rather than the English friend.
- There are only two known remaining Parselmouth in the Wizarding world, Voldemort's daughter, Delphini and Harry Potter, though it is possible that there are more unknown speakers, and Harry's children may have inherited the ability from him (though this is an unlikely, as Harry's knowledge of Parseltongue was artificially-gained rather than inherited).
