Parseltongue

Almost exclusively hereditary, to speak Parseltongue is to magically comprehend and verbally communicate with all snakes and snake-like beasts, like the Runespoor and Basilisk. This oral language has been associated with Dark wizards, owing to Salazar Slytherin's status as a Parselmouth which was passed on to the Gaunt family and Tom Riddle. However, outside of Wizarding Britain, no such association exists.
