ok guys but do you realize how interesting is parseltongue from a linguistic point of view. like.

• it’s a language that’s somehow like human languages, because Harry’s mind is able to wrap around it. This means it has to have a lexicon, a morphology (more or less complex) and syntax. Also, humans are able to communicate with each other in parseltongue as well, which means that it necessarily has to be a human-like language.
  
• the most famous linguist of the Wizarding World is, obviously, Noam Chomsssssssssky (greatest student of Ancient Runes and Arithmancy Slytherin has ever had)
  
• it’s a spoken language. and I mean literally spoken, which means it uses the vocal auditory channel (it could’ve been based on movement, like dances of bees). This means it has a developed phonology and that snakes use the vocal tract to speak, like us. Magizoologist should be very interested in studying how snakes’ minds process parseltongue, too! 
  
• parseltongue is the language of snakes, but also of species that are somehow related to serpents, like the Basilisk or the Runespoor, which actually aren’t (fully) snakes. Does this mean that parseltongue could have different dialects and accents, like human languages do?
  
• In book 7, Ron manages to speak (actually, imitate, but it works) parseltongue in order to open the Chamber of Secrets. Parseltongue is supposed to be hereditary, but can it be taught and learned?
  
• By the way, the hereditary thing would be a great point in favor of the generative grammar (that states that language’s most basic elements are essentially biological), because it’s inherited.
  

TL;DR: parseltongue is super interesting. My headcanon is that there’s a Linguistics department in the Ministry of Magic where wizard linguists study, among other things, the morphology of spells, the sociolinguistics implied in censoring Voldemort’s name and, of course, parseltongue.
