User blog comment:One True Slash/Voldemort's Snake/@comment-28293237-20160623103616

It is definitely a translation error. I just looked through my Harry Potter books and checked any mention of Nagini and her name is only ever spelt that way. Fun fact: Nagini isn't just a name invented by Jo. In some legends, a Nagini is a female entity/being/deity who can take the form of a large snake. I looked up the word Nagaine and the word doesn't seem to have any connection to the word Nagini. And Naginny is an even stranger translation - I don't know where the translator got that from! My first thought reading it was Ginny Weasley! Perhaps the translator was trying to give her a pet name to show some kind of affection between Voldemort and his pet ;)
