Even though it is not a human language per se and that one had to be gifted to be able to speak to snakes, why didn't Parselmouths teach others Parseltongue, at least in Slytherin house at Hogwarts?

Ron spoke Parseltongue from watching Harry speaking it in Chamber of Secrets. Hence Parselmouths aren't the only ones who can speak Parseltongue and be understood.

  • Because all the people who know Parselmouth were evil, (Neglect Harry's temporary Parselmouth) . Do you like to point out that Voldemort may have applied for Parseltongue teacher when he returned to Hogwarts instead of DADA.

Parselmouths are rare

There are very few confirmed Parselmouths during the events of the Harry Potter books. Harry himself, Voldemort, the Gaunts (Voldemort's relatives) - I think Dumbledore was said to be able to speak Parseltongue as well, but I may be making that up. That's a very, very small number.

Dumbledore had enough problems finding Defense Against the Dark Arts teachers to fill the position, I imagine it would have been even worse trying to find a Parselmouth to fill a teaching position as well; there are considerably more witches and wizards who know about (fighting) the Dark Arts than are able to speak Parseltongue. Add to that the fact that it was seen as a talent only possessed by those who had an affinity for dark magic and people may not even be willing to publicly admit to it.

It's not a particularly valuable skill

Ignoring Harry's very unique situation as The Boy Who Lived and his relationship to Voldemort, there's really no need to be able to speak Parseltongue. Your average witch and wizard could go their entire lifetime without being held back by not being able to talk to snakes.

Hogwarts student timetables were full enough already

Between classes, homework and revising for exams (when applicable) students had more than enough to occupy their time at school. I'm not sure they'd have enough time to dedicate to an additional lesson to learn a language.

    it must be the timetables!

    Dumbledore could understand Parseltongue, but not speak it.

    re: The first point, Parselmouths are rare because nobody teaches Parseltongue! That's a problem that would almost immediately solve itself as soon as you actually began teaching.

    +1 for it being a pretty useless skill. Why don't they all learn to speak troll?

    What does useless skill has to do with not being taught? This is in a wizard school where Firenze teaches how imprecise divination is, Professor Lockhart teaches how to capture pixies, and Professor McGonagall teaches how to turn a teapot to a turtle. Anyway, let's link scifi.stackexchange.com/q/65224/4918 Is Parseltongue a useful skill?

I've always been under the impression that Parseltongue is an inborn ability, not a teachable language, and it appears that J.K. Rowling holds the same opinion. I was just reading a transcript of her pivotal Q&A at Carnegie Hall (the one where she revealed that Dumbledore was gay), and it turns out she addressed exactly this question:

Q: Since Ron is able to speak Parseltongue in the last book, does that mean that Parseltongue is a language that most witches and wizards can learn or must a person be born with some ability to speak Parseltongue?

JKR: I don't see it really as a language you can learn. So few people speak it that who would teach you? This is a weird ability passed down through the Slytherin blood line. However Ron was with Harry when he said one word in Parseltongue, which I do not know so I cannot duplicate for you, but he heard him say "Open," and he was able to reproduce the sound. So it was one word. Whether he could learn to speak to snakes properly is a separate issue. I don't think he could. But he knew enough, he was smart enough, to duplicate one necessary sound.

She phrased it as an opinion rather than definite fact, but it's still hard to argue with. Plus, there's the fact that non-Parseltongues can't hear snakes speak, which makes it physically impossible for them to hold conversations with a snake. That means that as a language, Parseltongue would be limited to novelty secret-language status — hardly a useful thing to spend your time on.

  • This is a really good answer and deserves more votes.

    Anthony’s answer is logical and well-thought-out, but this one ought really to be the accepted one, because it gives the precise two reasons that Parseltongue isn’t taught: 1) it cannot be learnt (thus, it cannot be taught), and 2) non-Parselmouths cannot hear snakes. Anything else may be additional reasons, but these two are why teaching Parseltongue is not only not done, but actually impossible. Sep 27, 2015 at 13:44
  • Agree with Janus. This should be the accepted answer. The other is certainly logical and analysed well, offering some interesting thoughts. But the real reason is the language cannot be learnt. And frankly even if she phrased it as an opinion (I don't see it that way but to humour your suggestion) it seems to me with something like this that that is as good as canon; it's how she sees it and it is her universe and therefore it's how it is.

I was under the impression that being able to speak Parseltongue was considered a sign of bad character; Voldemort was a Parseltongue for one, and as the Snake is both part of his motif and also his sidekick (In Nagini), snakes were considered bad news..

I think that during The Chamber of Secrets, certain Hogwarts students take this out of proportion (as Children are wont to do) and as such the stigmatism attached to Parseltongues is perhaps not as aggressively pursued in the rest of the Poterverse as it is in the highly charged microcosm of Hogwarts.

In short, I'm not sure it'd be encouraged because although perhaps useful, it could be frowned upon: similar in our universe to teaching children how to hypnotize other kids or picks locks... Alohomora, however!

    No. Dumbledore says: ""Yes, indeed; a rare ability, and one supposedly connected with the Dark Arts, although as we know, there are Parselmouths among the great and the good too. In fact, his ability to speak to serpents did not make me nearly as uneasy as his obvious instincts for cruelty, secrecy, and domination." Apr 25, 2014 at 14:08

    This doesn't in any way bring conflict to my answer, which is in regard to the perception of Parseltongues post Voldemort. The question (and my answer) is not oriented around 'are parseltongues evil?', but in adressing the perception of them.. Apr 25, 2014 at 14:31

The language of snakes is Parseltongue.

As to why it isn't taught, there may be some contradictions in descriptions of Parseltongue; the Harry Potter wikia describes it as

a very uncommon skill, and is typically hereditary

which suggests it might not be so much that it isn't taught as that it can't be taught; you're either born a Parselmouth or you're not. But the Wikipedia entry describes it as a skill

acquired through learning or via a method of xenoglossia

Being a Parselmouth is described as being an attribute of a Dark Wizard, which probably means prejudice in the normal wizarding community contributes to it not being taught as a matter of course at Hogwarts.

  • Parseltongue it is. Thanks :)

    @Martha - Ron was able to imitate it (probably by essentially babbling until he got the right sounds) to get the chamber to open. That implies that one could learn it like any other language.

    Oct 25, 2013 at 15:01
  • @Compro01: that was Ron imitating what he'd heard Harry say. The point is, if you're not born a parseltongue, you can't even hear what a snake says, nevermind understanding it.

    @Martha yes, but one could still speak it without being able to hear the snake's reply. limits the usefulness of such learning, but doesn't make it impossible.

It is possible that Parseltongue is not taught because it is associated with Salazar Slytherin and Voldemort. And in the minds of the wizarding community, it is associated with evil. Prejudice is probably the reason why Parseltongue is not taught.


There is the possibility that Parseltongue cannot be learned. It is not a language, and it is magical in nature. When Harry speaks it (or listens to a serpent speaking it) he doesn't even realize he's not speaking English. This strongly hints that Parseltongue is actually closer to glossolalia (which is by definition miraculous / supernatural) than to real language skills.

You are not born with knowing your mother language, you learn it. however, you are born with Parseltongue.

When Ron imitated Parseltongue it was just how parrots imitate human speech. Parrots cannot learn a human language, they just record and replay a few phrases as they would do it with any generic sound effect.

Another hint to it not being a real language is that WTF snakes are sentient????

This means Parseltongue is either completely impossible, or extremely difficult to learn.

  • Read my mind. is this possible? and if it is, is it probable?
